A stunning 49-point outburst from Memphis Grizzlies star Ja Morant carried his side back from a 16-point first-half deficit to defeat the Houston Rockets 129-122 on Friday.

Morant had 18 points and six assists in the first half, but the rest of the Grizzlies were struggling, falling into a 42-26 hole early in the second quarter before trimming the margin to 70-62 at halftime.

The second pick from the 2021 NBA Draft, Jalen Green, showed why Rockets fans are so excited as he piled up 33 points on 13-of-21 shooting while going four-of-five from long range, but Morant was matching him step-for-step before running away late.

Memphis won the fourth quarter 34-22 as the Rockets ran out of gas, with Morant finishing 17-of-26 from the field, and five-of-six from long range, while adding eight assists, four rebounds, two blocks and a steal. He had 31 in the second half, and only a missed free throw in the fourth quarter kept him from scoring 50.

In an eye-catching performance, second-year center Alperen Sengun tallied 23 points (nine-of-13 shooting) with 12 rebounds in 27 minutes off the Houston bench.

Beal wins it for the Wizards

The Washington Wizards are now 2-0 after a Bradley Beal game-winner with seven seconds remaining handed his side a 102-100 win over the Chicago Bulls.

Chicago trailed by nine points with less than five minutes to play, but from that point on DeMar DeRozan dropped 11 of his 32 points (11-of-23 shooting), tying things up at 98-98 with a minute remaining after a pair of free throws.

Beal answered back with a layup, and DeRozan leveled the score again with a dunk, before Beal sank the dagger to finish with 19 points (nine-of-14 shooting) and eight assists. DeRozan had a chance to win it with a three-pointer on the buzzer, but could not deliver.

Brown and Tatum carry the Celtics

The combination of Jaylen Brown and Jayson Tatum proved too much for the Miami Heat to overcome, with the duo combining for 57 points in the Boston Celtics' 111-104 triumph.

Tatum finished with 29 points on 10-of-22 shooting, getting to the line and hitting all seven of his free throws, while Brown was more efficient from the field, hitting 12-of-18 shots for 28 points after they scored 35 each in Boston's season opener.

The Heat could not survive in the minutes center Bam Adebayo had to sit down, as the big man posted 19 points (eight-of-11 shooting) with eight rebounds, five assists, two steals and a plus/minus of plus 20 in his 35 minutes. Unfortunately for Miami, they were minus 26 in the 12 minutes he was on the bench.

Simmons banks first win as a Net

The Brooklyn Nets won their first game with Ben Simmons as they defeated the Toronto Raptors 109-105 at home.

Simmons was solid without contributing much on the scoreboard, finishing with six points (three-of-five shooting), but he grabbed 10 rebounds, dished eight assists and blocked two shots.

Kyrie Irving and Kevin Durant carried the scoring load, as Irving top-scored, producing 30 points on 11-of-24 shooting while adding seven assists, while Durant hit eight-of-18 shots for 27 points and six assists.

Marcus Smart credited his own "maturity" for not escalating an altercation with Joel Embiid in which he claimed the Philadelphia 76ers center tried to break his arm.

Reigning Defensive Player of the Year Smart has had a long-standing rivalry with Embiid.

The Boston Celtics guard has been ejected eight times in his NBA career, with one of those coming against the 76ers in 2019 after he shoved Embiid to the ground when his back was turned.

Smart stayed on the court on Tuesday, although he was whistled for a technical foul – the third against the 76ers of his career – following another tussle with Embiid in a 126-117 Celtics win.

The players' arms became tangled as they battled for a rebound, before Smart angrily grabbed the ankle of Embiid, who dropped to the floor.

Embiid, who has only once been ejected from an NBA game and never against the Celtics, avoided punishment.

"I went for a rebound. Basketball play," Smart said. "I went for the steal. Basketball play. The referee blows his whistle, calls a foul.

"I stop playing, my arm's still stuck in there, and [Embiid] tries to break it. And then I'm the only one who gets a tech. Everybody saw it."

He added: "I don't have to keep talking about it. If I did that, I'm probably ejected, suspended three games, four games, fined.

"But the fact that I was the only one that got something out of that is beyond me. Especially as defending DPOY, and that's how he gets treated. It's tough.

"It's maturity. I could have cracked his head open, but I didn't. And that's the maturity we have.

"So, we move on from it. It is what it is, and we control what we can control."

The Boston Celtics left a tumultuous offseason behind them on opening night to deliver a first win for interim head coach Joe Mazzulla, as Jayson Tatum said: "We're all in this together."

Mazzulla was making his coaching bow against the Philadelphia 76ers on Tuesday having replaced Ime Udoka for this NBA season.

Udoka, who led the Celtics to the NBA Finals in his first year as coach in 2021-22, was suspended by the team for the entire campaign for "violations of team policies" following an "improper" consensual relationship with a female staff member.

Assistant Mazzulla has temporarily stepped up to the top job, but there was no sign of the saga impacting the Celtics' play in their 126-117 victory over the highly fancied 76ers.

Tatum had 35 points and 12 rebounds in 39 minutes, as team-mate Jaylen Brown – reportedly part of trade talks for Kevin Durant earlier this year – also scored 35 points in 39 minutes.

Tatum and Brown became the first pair of team-mates to each score at least 35 points in a season opener since Los Angeles Lakers duo Wilt Chamberlain (35) and Jerry West (39) in 1969-70 – likewise against the 76ers.

Keeping both performing at a high level will be key to Mazzulla's hopes this year.

"He wouldn't have took any of the credit for tonight," Tatum said of Mazzulla. "But the thing that I like about Joe and admire about him is that he's very honest that he doesn't know everything.

"He wants us to help him out as much as he's helping us out. It's like we're in a relationship, and we're all on the same page and trying to accomplish the same thing. We're all in this together."

Mazzulla added: "I'm grateful for the relationship we have. These guys have been through a lot together, and they're great players, so it's just a matter of working together.

"So, I appreciate their trust and buy-in, but they come up with a lot of good stuff as well, and we kind of just figure it out."

The Golden State Warriors have begun their title defense in fine fashion, defeating the Los Angeles Lakers 123-109 at home on the opening night of the NBA season.

With the Warriors receiving their championship rings in a ceremony before the game, they were determined to make it a night to remember, with reigning Finals MVP Stephen Curry leading the way.

Curry finished with 33 points on 10-of-22 shooting, hitting four-of-13 from long range and all nine of his free throws to lead both teams in scoring. He also chipped in seven assists, six rebounds and four steals.

Jordan Poole had 10 of his 12 points in the first half to lead the Warriors to a 59-52 halftime lead, before Klay Thompson took over to begin the third quarter, scoring his side's first seven points on three consecutive shots to ignite a 32-19 frame, blowing the game open in the process.

The Warriors' lead peaked at 91-64 late in the third quarter, before the visiting Lakers scored 38 in the fourth to trim the final score to a respectable figure.

In his 20th season, LeBron James looked as strong as ever, finishing with 31 points (12-of-25 shooting) with 14 rebounds and eight assists, while Anthony Davis had 27 points (10-of-22 shooting) with six rebounds, four steals and two blocks, although Davis posted the worst plus/minus of the game at minus 21.

Tatum, Brown combine for 70 in Celtics win

In what was officially the first game of the season, the Boston Celtics and interim head coach Joe Mazzulla collected an impressive 126-117 home win against the Philadelphia 76ers.

The Celtics had to compete with a spectacular James Harden performance, who led the 76ers with 35 points on nine-of-14 shooting, including five-of-nine from long range and 12-of-12 from the free throw line, while adding eight rebounds and seven assists.

Harden had a plus/minus of plus one in his 37 minutes, meaning the 76ers were outscored by 10 in the 11 minutes he was on the bench.

For Boston, Jayson Tatum and Jaylen Brown were almost unstoppable all night, scoring 35 points each at a combined 61 per cent from the field (27-of-44), while Tatum also grabbed 12 rebounds and Brown had two steals.

New signing Malcolm Brogdon showed no signs of needing an adjustment period, making an immediate impact off the Celtics' bench with 16 points (seven-of-11 shooting) and four assists in 24 minutes.

The NBA season is finally here, with the Golden State Warriors looking to defend their title after defeating the Boston Celtics in this year's NBA Finals.

Golden State will have plenty of serious opposition in their way if they are to go back-to-back, as some powerhouses – like the Los Angeles Clippers and the Milwaukee Bucks – return to full health.

The list of contenders this year may be as deep as it has ever been, with the Philadelphia 76ers, Denver Nuggets and Phoenix Suns all definitely believing they have what it takes, and young sides like the Memphis Grizzlies and the Minnesota Timberwolves going all-in with the cores they have assembled.

After one of the best rookie classes in recent memory last season, this year's draftees have plenty to live up to, so to preview the season, we will start at the top.

Who are the favourites?

Despite not making the NBA Finals this past season, any conversation about potential champions in 2022-23 begins with Giannis Antetokounmpo and the Bucks.

The Bucks took the Celtics to Game 7 in the Eastern Conference Finals, and that was while they were missing their second-best player as Khris Middleton was sidelined for the entire series after suffering a knee injury in the first round. 

There is a convincing case to be made that they would have gone back-to-back with a healthy Middleton, but instead, the Warriors were able to take care of business in the Finals and collect the fourth championship of the Stephen Curry, Klay Thompson and Draymond Green era.

Golden State return almost their full team, and with even marginal improvement from second-year lottery picks Moses Moody and Jonathan Kuminga, they will be one of the deepest rosters in the league, and will have the ammunition to put together one of the better trade packages if a disgruntled star appears around the deadline.

The Celtics will likely remain one of the best defensive units in the league, and will therefore always have a chance in the playoffs, and if the Warriors are not to come out of the Western Conference, the Nuggets or the Clippers are finally healthy and poised to make some noise.

Who are the dark horses?

Despite winning the title in 2019, the Toronto Raptors will come into this season extremely under the radar in what is now a loaded Eastern Conference.

One of the biggest and most athletic teams in the league, the thing working in the Raptors' favour may also be the point working against them – they brought back almost the exact same team.

Focal points Fred VanVleet and Pascal Siakam are still only 28 years old, while O.G. Anunoby profiles as a potentially elite wing at 25-years-old, and 21-year-old second-year point forward Scottie Barnes is the reigning Rookie of the Year.

They were the five seed last year despite all of their starters missing significant time, and with their championship experience and natural improvement, they will be in the mix by default.

Out West, it's hard to go past the New Orleans Pelicans, who will have one of the best starting fives in the NBA.

With C.J. McCollum, Brandon Ingram and surprise packet Herb Jones on the perimeter, along with Jonas Valanciunas and the returning Zion Williamson inside, that group will be a tough out if Williamson can remain healthy.

Who will win Rookie of the Year?

The clear favourite to take home the honour as the best first-year player is the Orlando Magic's Paolo Banchero, who was selected first overall in June's NBA Draft.

Banchero – who at six-foot-10 and 250lbs is the same size as prime DeMarcus Cousins despite playing on the perimeter – has essentially been tasked with being the saviour of the franchise, and will have significant playmaking and scoring responsibilities from day one.

He could realistically average somewhere in the range of 20 points, five rebounds and five assists per game if the franchise truly decides to put the ball in his hands and let him run the show, and he is the only player in the class that can be said about.

His biggest competition – literally – was the Oklahoma City Thunder seven-footer Chet Holmgren, who was taken second overall, but will miss the entire season after suffering a fracture in his foot in the preseason.

Third pick Jabari Smith Jr will likely be more of an off-ball player in year one, limiting his ability to rack up massive counting stats, and fifth pick Jaden Ivey will be sharing the floor with last year's top overall selection Cade Cunningham with the Detroit Pistons, where Cunningham is unquestionably the star.

Keegan Murray, the fourth overall pick by the Sacramento Kings, profiles as one of the better all-around scorers in the draft and will have the opportunity to make his mark, and Shaedon Sharpe showed some intriguing flashes in the preseason after not playing a single game of competitive basketball since graduating from high school, still earning the seventh overall pick by the Portland Trail Blazers.

Quick hitters:

– Pelicans wing Herb Jones was never going to receive the credit he deserved last year as a 23-year-old second-round draft pick, but the rookie was quietly one of the best defensive players in the league last season.

As a rookie, he was guarding the best opposing perimeter player every night for the Pelicans, suiting up for 78 of the 82 regular season games and finishing top-10 in the league in deflections per game (3.1).

He is one of the only wings in the NBA who is tasked with carrying his side defensively, and health permitting, he will be honoured on the NBA All-Defensive teams this season.

– For those who do not play fantasy basketball, it must be a shock to hear Indiana Pacers guard Tyrese Haliburton has emerged as a first-round pick, but the unbelievably efficient 22-year-old is in position to have an explosive breakout season.

After being traded to the Pacers last season, Haliburton averaged 17.5 points, 9.6 assists, 4.3 rebounds and 1.8 assists while shooting 50 per cent from the field, 41 per cent from three and 85 per cent from the free throw line, putting him in the top echelon of efficient guard scorers and playmakers.

With established veterans Buddy Hield and Myles Turner both reportedly on the trading block as the Pacers enter themselves into the Victor Wembanyama sweepstake, their departure would only amplify the massive season coming from the former Sacramento draft pick.

– The Cleveland Cavaliers will have their sights set on the playoffs this season after their aggressive trade for former Utah Jazz star Donovan Mitchell – but he may not even be the best guard on the Cavs roster.

Last season was a coming out party for point guard Darius Garland, who appears to be next up in the archetype of deep-shooting, slick-passing, small initiators. 

He shot a career-best 46 per cent from the field this past season while attempting a career-high 6.7 three-pointers per game, and he was also one of the best passers in the league, averaging 8.6 assists and forming spectacular chemistry with fellow All-Star and alley-oop partner Jarrett Allen.

Mitchell will bring a level of perimeter scoring and playoff pedigree to the Cavaliers that is desperately needed to lower the demands on Garland late in games, but it will be Garland running this team for the first 46 minutes.

The NBA is back, which means excitement for most fanbases – but anxiety for others.

The new season should ensure a clean slate for everyone, but some situations have been allowed to fester in recent months without the distraction of on-court action.

Now, even with basketball returning, developments around Kevin Durant's future might prove every bit as intriguing to the neutral as anything that happens in the regular season.

And Durant and the Brooklyn Nets are not the only player-team combo in a tricky spot heading into the year...

Everyone at the Lakers

Before considering the wide-ranging implications of Durant's trade request, let's check in on last year's team in crisis.

Plenty of outsiders could have forecast difficulties for the Los Angeles Lakers in 2021-22, with LeBron James and Anthony Davis joined in a 'big three' by Russell Westbrook – at this stage in his career, consistent only in using up a huge number of possessions.

Westbrook had averaged a usage rate above 30 per cent in every season between 2014-15 and 2020-21, with his average over the seven seasons (34.6 per cent) only narrowly trailing James Harden's league-leading 34.7 per cent (minimum 500 possessions). A ball-dominant player on often mediocre teams, Westbrook's winning percentage of 59.2 ranked 109th over this period among those to play 100 or more games. Harden (66.2) was a far more respectable 29th.

Although his usage dipped to 27.5 per cent around better players in LA, Westbrook remained every bit as erratic as expected and, unfortunately for the Lakers, played more than 500 more minutes than any team-mate – comfortably ahead of an ageing James and bulkier Davis.

The three superstars started just 21 games together and even then only scraped a winning record at 11-10.

Having missed the playoffs – and even the play-in – in 11th in the West, the Lakers fired coach Frank Vogel, perhaps optimistically hoping he alone was the problem, and brought back each of James, Davis and Westbrook.

Seemingly determined to further upset a team who won the title just two years ago, the Lakers were also linked with a move for Kyrie Irving before settling instead on Patrick Beverley, who might prove only marginally less disruptive.

Westbrook and Beverley have repeatedly clashed in the past, although the new Lakers signing has described his team-mate as "someone I always wanted to play with", praising his "competitive spirit, that fire, that will, that dog, that nastiness, that grit".

New coach Darvin Ham thinks the pair can work together, but the potential for fireworks is considerable even before taking into account James' own "competitive spirit".

Kevin Durant and Kyrie Irving at the Nets

The 2019 free agency moves for Durant and Irving certainly made the Nets relevant. But they haven't yet made them successful. And right now, Brooklyn might be the most explosive environment in the NBA.

Durant missed their first year together with an Achilles injury sustained playing for the Golden State Warriors, yet the Nets have still only won seven playoff games in the past three postseasons – all seven of those wins coming in a short-lived 2020-21 run.

Last season, as they had been in their first season with Durant and Irving, Brooklyn were swept in the first round. It concluded a miserable campaign that was not about to get better in the offseason.

With Irving unvaccinated and so unable to play in New York City until March, he and Durant started only 17 games together in the regular season. The Nets had started the season with their own 'big three', but Harden – much to his frustration – appeared just twice alongside the star pairing before he was traded to the Philadelphia 76ers. Ben Simmons came in the other direction and did not play once.

Far from a happy camp, when Irving then opted in to the final year of his contract in late June, the Nets were vulnerable to a trade request from Durant, which quickly followed.

However, with four years remaining on his own deal and Brooklyn asking for a huge price in trade talks, it was reported Durant had returned to the Nets and promised to stay if head coach Steve Nash and general manager Sean Marks were replaced.

Ultimately, Durant "agreed to move forward with our partnership" – as Marks phrased it – regardless, with Nash saying in September his relationship with the superstar was "good".

"I love the guy," added Nash, who understood Durant being "seething" at the end of the season. "Families have issues. We had a moment, and it's behind us. That's what happens."

In theory – especially if Simmons can return to his two-time All-Defensive First Team best – the Nets could have a great team in 2022-23.

Yet based on how this project has gone so far, it is not difficult to imagine a scenario in which Brooklyn endure another desperately disappointing season and are again left attempting to convince Durant to stay.

James Harden at the 76ers

The 76ers moved one miserable superstar in Simmons for another in Harden, which was only enough to take them as far as the Eastern Conference Semifinals last year.

And en route to that unsatisfactory conclusion, team-mate Joel Embiid was not shy in criticising Harden, repeatedly calling on him to be more aggressive while recognising he is no longer "the Houston James Harden".

It was an understandable complaint; Harden attempted only 13.6 field goals per game for the Sixers in the regular season – little more than half the number of shots he was taking in 2018-19 for the Houston Rockets (24.5), when he scored a career-high 36.1 points per game. He was also only making 40.2 per cent of his field goal attempts in Philly, down on every other season in his career.

So far, it is fair to say this has not worked. Doc Rivers, in a training camp clip published by the NBA, told Harden he and Embiid needed to "listen to each other" and acknowledged the partnership needed work as it was "unnatural".

Echoing some of Embiid's complaints, coach Rivers said: "You can't just say you're a facilitator. I need you to be a scorer and a facilitator."

Rivers for now believes it can still be fixed. "When it clicks, James, we're going to be unbeatable," he told a player who, for his part, agreed to a restructured contract that allowed Philly to bolster their roster in the offseason.

But this team – and certainly Embiid – might argue more help would not be required if Harden played in the manner he is capable.

"We've got to establish Joel and you – it's a pecking order," added Rivers. "This ain't a democracy."

Embiid may not believe this is "the Houston James Harden", but the team and Harden himself seemingly do, with the former Rocket announcing: "If my conditioning can be level with my skill set and my IQ and the work that I put in, it's MVP – and I feel like my conditioning is where it needs to be."

Harden needs to start showing that, or this time his team might tire of him, rather than the other way around.

Jaylen Brown at the Celtics

Little has gone to plan for the Boston Celtics since winning Game 3 of the 2022 NBA Finals, as they lost the next three to the Warriors and then saw preparations for a bounce-back season in 2022-23 rocked by a number of key absences.

Boston will begin the year without new signing Danilo Gallinari, who tore his ACL playing for Italy, Robert Williams, who has also undergone knee surgery, and, crucially, coach Ime Udoka.

Udoka had turned around his first season as a head coach spectacularly, with the Celtics tied for ninth in the East at the turn of the year after a 17-19 start before leading the conference the rest of the way (34-12) to take the second seed.

But a year-long suspension for Udoka "for violations of team policies" was announced by the team last month.

And even between the ultimately disappointing postseason and repeatedly disrupted preseason, not everything was rosy, with Boston also impacted by the Durant saga.

When Durant looked to be on the move, reports claimed the Celtics had offered the Nets a package that included Jaylen Brown. That trade did not materialise, of course, but it is difficult to imagine Brown was too impressed.

In recent seasons, Brown has been hugely valuable to the Celtics – not least because he is being paid below his value.

Brown is one of only 11 players who has scored at least 1,400 points at an average of at least 23.5 per game in each of the past two seasons. Of the other 10, four have current or future contracts with an average annual value of more than $50m, another four are being paid over $40m per year, and the final two are bringing in a salary in excess of $30m a season.

Brown's deal, which ranks outside the top 50 contracts in the NBA in both total value and average annual value, earns him $26.6m each year.

And the rules around NBA extensions will prevent Brown being paid on par with his contemporaries unless he makes All-NBA in one of the two seasons remaining on his contract.

In theory, that carrot should encourage Brown to enjoy another big season, but at a franchise as fractured as the Celtics have suddenly become, focus could understandably drift instead towards free agency in 2024.

Shai Gilgeous-Alexander at the Thunder

Unlike the other teams on this list, the Oklahoma City Thunder do not have the pressure of needing to win now – but that is part of the problem.

OKC moved on their ageing stars, loaded up on draft picks and put together a young core that includes Chet Holmgren, Josh Giddey and Shai Gilgeous-Alexander. That is all very exciting... or at least it will be.

Rookie Holmgren is down for the year, seemingly making this another season in which the Thunder will lose games and then see what they can do in the draft.

That is no great issue for 20-year-old Holmgren or 19-year-old Giddey, but it does not suit Gilgeous-Alexander, now 24 and entering his fifth year, quite so much – even if he also starts the year injured.

Among the 63 players to score 2,000 or more points across the past two seasons combined, Gilgeous-Alexander ranked 18th for points per game (24.2). He ranked 61st for wins (32).

This is not a case of an average player stat-padding on a bad team; he is simply too good to be in this situation.

And having agreed a five-year extension in August ahead of Holmgren's injury, it appeared Gilgeous-Alexander had unknowingly signed up for more of the same.

He disagrees, insisting: "I know what I signed up for when I signed a five-year extension. I don't think we're going to be losing for much longer. It's not like I signed up to lose."

But lose they will, if they have any sense – and past experience suggests they do.

Without Holmgren, the Thunder are not going to be in any position to seriously compete, which opens up the possibility to pick high in a draft that includes a potentially generational talent in Victor Wembanyama.

At some stage, OKC will be ready, but that is not now, and Gilgeous-Alexander could be forgiven for finding his patience waning.

The Boston Celtics and veteran forward Blake Griffin have agreed to a one-year contract, ESPN's Adrian Wojnarowski reported on Friday.

Griffin, 33, will add depth for a team that has endured a series of injuries in the frontcourt before the 2022-23 season has even begun.

Danilo Gallinari, Boston's top free agent acquisition of the offseason, suffered a torn ACL in August, while starting center Robert Williams III underwent knee surgery last week, keeping him away from basketball activities for at least two months.

A six-time All-Star selection, Griffin averaged 6.4 points and 4.1 rebounds in 56 games with the Brooklyn Nets last season.

Griffin's signing comes in the wake of coach Ime Udoka's year-long suspension for an inappropriate workplace relationship that is still clouded in mystery.

The Celtics tip off their season on October 18 against the Philadelphia 76ers.

Boston Celtics head coach Ime Udoka has officially been suspended by the franchise for the entire 2022-23 season for an "improper" consensual relationship with a female staff member.

Udoka, who in his first year as a head coach guided the Celtics to their first NBA Finals appearance since 2010, will be replaced by assistant Joe Mazzulla as interim head coach, according to ESPN's Adrian Wojnarowski.

Mazzulla was considered a finalist for the Utah Jazz head coaching role that ended up going to fellow Celtics assistant Will Hardy, after former Celtics general manager Danny Ainge took the top role in Utah.

In a 46-word statement on Thursday night, the Celtics confirmed reports from ESPN and The Athletic that they have opted to sideline Udoka for the full season for what they call "violations of team policies".

Udoka also released a brief apology, saying: "I want to apologise to our players, fans the entire Celtics organisation, and my family for letting them down. I am sorry for putting the team in this difficult situation, and I accept the team's decision. Out of respect for everyone involved, I will have no further comment."

Boston Celtics head coach Ime Udoka is reportedly facing "a significant suspension" for violating "organisational guidelines", according to ESPN's Adrian Wojnarowski.

The report is incredibly vague and lacking in any detail about what exactly Udoka did to warrant a significant internal response from his Celtics bosses, however it does say it is believed he is not in danger of getting fired.

Hours later, The Athletic's Shams Charania added that Udoka had "an improper intimate and consensual relationship with a female member of the team staff", which has been deemed a violation of the Celtics' code of conduct.

After Udoka's top assistant, Will Hardy, was hired as the new head coach of the Utah Jazz, Boston's Joe Mazzulla is the favourite to take over in the interim role.

Udoka, 45, became the fifth rookie head coach in the past 25 years to take his team to the NBA Finals this past season when his Celtics emerged as the best defensive team in the league. 

He is also the first rookie head coach to win multiple Game 7s in his first playoff run, taking out both the Miami Heat and the reigning champion Milwaukee Bucks.

Boston Celtics centre Robert Williams III reportedly will miss between 4-to-6 weeks after undergoing arthroscopic left knee surgery this week, according to ESPN's Adrian Wojnarowski.

It is the second surgery on the same knee in six months for Williams, who had a meniscus procedure performed March 30. That specific surgery enabled Williams to recover quicker and return to the court for Boston’s run to the NBA Finals.

The 24-year-old Williams injured the knee in a win over the Minnesota Timberwolves on March 27, forcing him to miss the final seven regular-season games and Boston's first two playoff contests.

He came off the bench in Games 3 and 4 of the Celtics' first-round sweep of the Brooklyn Nets, and started the first three games of the Eastern Conference semi-final series with the Milwaukee Bucks before suffering a bone bruise in the same knee in Game 3.

He missed the remainder of the seven-game series with the Bucks before returning to start Game 1 of the Eastern Conference finals against the Miami Heat.

Another knee injury sent him back to the bench for Game 3, but he then played the rest of Boston's seven-game series with the Heat and every game of Finals with the Golden State Warriors.

Williams has battled injuries throughout his four-year career and wasn't as effective in last season's playoffs compared to the regular season, averaging 7.7 points on 67.9% shooting, 6.2 rebounds and 2.2 blocks in 17 playoff games.

In 61 regular-season games last season, he averaged 10 points on 73.6% shooting, 9.6 boards and 2.2 blocks.

The Celtics went 40-21 in the regular season when he played and 11-10 when he didn't suit up.

Without one of the league's premier rim protectors, veteran Al Horford will be tasked with playing more minutes until Williams returns early in the regular season.

Boston tips off the 2022-23 season on October 18 against the rival Philadelphia 76ers.

Brooklyn Nets star Kyrie Irving thinks his team "needed" their 4-0 loss to the Boston Celtics in last season's NBA playoffs.

That chastening first-round exit to Irving's former team brought to an end a frustrating campaign for the much-fancied Nets.

With Irving being teamed with Kevin Durant and James Harden, many felt Brooklyn were the favourites to go all the way.

However, Irving only made 29 appearances in all for the Nets, mainly due to his unvaccinated status meaning he could not play any home games until late in the season when the ban in New York on unvaccinated players was lifted.

Durant also missed some games through injury, while Harden struggled for form before being traded to the Philadelphia 76ers in exchange for Ben Simmons, who is yet to make his Nets debut.

Speaking on Twitch for streamer KaiCenat, Irving said: "We got 4-0'd my G, we got 4-0'd. It was meant to happen like that. Motivation, bro.

"We needed that humbling experience, especially going against the Celtics. It was already built to be that match-up.

"We're going to see them again, we're going to have to. They're going to be where they're going to be. But those young'uns over there in Boston, bro, I got to see them grow up.

"So to see them do what they did last year on the Finals stage, making it that far, I'm glad they had to go through us."

Irving – who exercised his $37million player option with the Nets for next season in June – still managed to average 27.4 points per game last year, as well as 4.4 rebounds and 5.8 assists.

Boston Celtics forward Danilo Gallinari could miss most or all of the upcoming NBA season, according to reports, after tearing the anterior cruciate ligament in his left knee last week.

Gallinari was injured playing for Italy in a FIBA World Cup qualifying game against Georgia on Saturday. The Italian national team later announced the veteran sharpshooter sustained a torn meniscus, without providing further details.

ESPN reported on Friday that Gallinari was hopeful of returning late in the 2022-23 season. Typical recovery time for an ACL tear is anywhere from six to 12 months.

The Celtics confirmed on Twitter on Friday: "Danilo Gallinari has been diagnosed with a torn ACL in his left knee. Gallinari sustained the injury while playing for his home nation of Italy in a FIBA World Cup qualifier against Georgia on August 27. Further updates will be provided as appropriate."

Gallinari previously tore the ACL in the same knee while playing for the Denver Nuggets late in the 2012-13 season. That injury required an additional surgery that sidelined him for the entire 2013-14 campaign.

The 34-year-old signed a two-year, $13.3million contract with Boston in July, just days after being waived by San Antonio. Gallinari was acquired by the Spurs from Atlanta on June 30 as part of the trade that sent All-Star point guard Dejounte Murray to the Hawks.

Gallinari, who averaged 11.7 points and 4.7 rebounds in 66 games with the Hawks last season, was being counted on to provide bench scoring for a Celtics team coming off an appearance in the NBA Finals.

He also took to Twitter on Friday to post a statement, saying: "This has been a tough week for me as I have learned the extent of my injury. This game means everything to me and not being able to be on the court with my Celtics teammates hurts.

"I plan to give everything I can to the Celtics organisation and my teammates as we hunt for a title. I will work tirelessly with the Celtics staff to return to the court as soon as I can and I appreciate the unwavering support from the fans, my teammates, and the entire NBA family."

The 13-year veteran is one of only six players to average at least 15 points per game and shoot 40 per cent or better from three-point range over the last four seasons (min. 100 games), along with 2022 All-Stars Stephen Curry and Karl Anthony-Towns, Kyrie Irving, T.J. Warren and Bojan Bogdanovic.

The NBA has made the historic decision to retire the number six from all franchises' jerseys to honour the legacy of Boston Celtics icon Bill Russell, who passed away on July 31 at 88 years old.

It is the first time in history that a jersey number has been retired league-wide, and in addition, every jersey and every home court in the 2022-23 season will feature a clover-shaped logo bearing the number six.

Russell holds the record for winning the most NBA Championships, collecting 11 rings from 1957 to 1969 while winning five league MVP awards.

Across his career, Russell averaged 15.1 points and 22.5 rebounds per game, and at nearly seven-feet tall while being a world-class high-jumper and sprinter, is considered arguably the sport's greatest ever defensive player.

Since 2009, the NBA Finals MVP award has been named after Russell.

While his competitive achievements place him amongst the greatest to ever lace up a pair of basketball shoes, his off-court legacy is just as significant, as he became one of the faces of the American civil rights movement.

Russell was regularly pictured with Martin Luther King Jr, Muhammad Ali and Kareem Abdul-Jabbar as the public faces of the campaign for civil rights in the United States, and in 2011, then-president Barack Obama awarded Russell the Presidential Medal of Freedom for his accomplishments both on and off the court.

In a statement, NBA commissioner Adam Silver said: "Bill Russell's unparalleled success on the court and pioneering civil rights activism deserves to be honoured in a unique and historic way. 

"Permanently retiring his number six across every NBA team ensures that Bill's transcendent career will always be recognised."

Tom Brady remembered Bill Russell as a sporting figure with "a great presence" as he recalled striking up a rapport with the Boston Celtics great, who died on Sunday.

NFL superstar Brady told a news conference about his sorrow at hearing of Russell's death at the age of 88.

He had come to know the basketball hero when living in the Boston area, while spending 20 seasons as quarterback with the New England Patriots.

Russell was drafted by the Celtics in 1956 and went on to win 11 NBA titles. He was a five-time NBA MVP and is one of only four players to have been named to all four NBA anniversary teams (25th, 35th, 50th and 75th).

He became the first black head coach of any North American professional sports team, leading the Celtics to back-to-back NBA championships in 1968 and 1969 when he served as a player-coach.

Russell also made a significant impact away from the basketball court, championing the civil rights movement, and Barack Obama awarded him the Presidential Medal of Freedom in 2011.

Brady said: "I knew him pretty well. I had a lot of time up there in Boston and got to know him and he was a very impactful figure.

"Going back to my early days with the Patriots, in my second year at training camp he came and spoke to the team.

"A really imposing figure, he had a great presence around him and obviously what he overcame in his career was pretty unbelievable. It was a sad day."

Chicago Bulls hero Michael Jordan on Sunday described Russell as a "pioneer" and a "legend", while Obama also paid tribute to "a giant".

The Celtics said Russell's "DNA is woven through every element" of the organisation.

Michael Jordan has hailed Bill Russell as a "pioneer" and a "legend", while the Boston Celtics and Barack Obama also paid glowing tributes to the basketball legend after he died on Sunday.

Russell's family announced that he had passed away peacefully at the age of 88.

One of the all-time greats, Russell won 11 NBA titles, was a five-time NBA MVP and is one of only four players to have been named to all four NBA anniversary teams (25th, 35th, 50th and 75th).

He was the first black head coach of any North American professional sports team, leading the Boston Celtics to back-to-back NBA Championships in 1968 and 1969.

Russell also made a huge impact off the court, championing the civil rights movement and Obama awarded him the Presidential Medal of Freedom in 2011.

The legendary Jordan said: "Bill Russell was a pioneer – as a player, as a champion, as the NBA's first black head coach and as an activist.

"He paved the way and set an example for every black player who came into the league after him, including me. The world has lost a legend. My condolences to his family and may he rest in peace."

The Celtics said Russell's "DNA is woven through every element" of the organisation.

"To be the greatest champion in your sport, to revolutionise the way the game is played, and to be a societal leader all at once seems unthinkable, but that is who Bill Russell was," the NBA franchise stated.

"Bill was a champion unlike any other in the history of team sports – an 11-time NBA champion, including winning eight consecutive titles, a five-time MVP, an Olympic gold medalilst and the NBA’s first Black head coach.

"Bill Russell's DNA is woven through every element of the Celtics organisation, from the relentless pursuit of excellence, to the celebration of team rewards over individual glory, to a commitment to social justice and civil rights off the court. 

"Our thoughts are with his family as we mourn his passing and celebrate his enormous legacy in basketball, Boston, and beyond."

Former United States president Obama posted on Twitter: "Today, we lost a giant.

"As tall as Bill Russell stood, his legacy rises far higher – both as a player and as a person.

"Perhaps more than anyone else, Bill knew what it took to win and what it took to lead. On the court, he was the greatest champion in basketball history. Off of it, he was a civil rights trailblazer – marching with Dr. King and standing with Muhammad Ali.

"For decades, Bill endured insults and vandalism, but never let it stop him from speaking up for what's right. I learned so much from the way he played, the way he coached, and the way he lived his life."
