DeMar DeRozan knocked down a buzzer-beating three-pointer as Eastern Conference leaders the Chicago Bulls dramatically defeated the Indiana Pacers 108-106.

The Bulls ended 2021 on a high with a sixth straight victory that came about when DeRozan picked up the ball with around nine seconds remaining, looked around for options on the court before taking on the shot himself when he noticed the clock winding down.

It was the second time in DeRozan's career he had hit a buzzer-beater, while no Bulls player had achieved the feat since Jimmy Butler in 2016.

DeRozan drained 28 points in total to go with six assists and three rebounds, while Coby White had 24 points. DeRozan is the league leader for both total points and points per game in the fourth quarter.

Victory sees the Bulls head into the new year top of the East, with an identical record (23-10) to the Brooklyn Nets.

Celtics stop the skid to down Suns

The Phoenix Suns entered their showdown with the Boston Celtics with the best record in the NBA but lost for the third time in four games with a 123-108 defeat.

Jaylen Brown and Marcus Smart each scored 24 points with the former registering 11 rebounds and the latter eight assists as the Celtics stopped a three-game losing streak. Robin Williams had a triple-double of 10 points, 11 assists and 11 rebounds.

Deandre Ayton and Jae Crowder missed a third straight game for the Suns due to being placed on the health and safety protocols. Devin Booker put up 22 points, Cam Johnson had 20, Jalen Smith registered 19, and Chris Paul had 14 points and eight assists, but it was all in vain for the Suns.

LeBron James had a season-high 43 points and extended his streak of 30-point games to seven as the Los Angeles Lakers routed the Portland Trail Blazers 139-106 to improve to 18-19 on the season.

Bulls on a hot-streak

Chicago's six-game winning streak has propelled the Bulls to the top of the East and represents their best winning run since December 2017.

Moreso than any other team in the NBA, the Cleveland Cavaliers have lived at opposite ends of the league over the last two decades. 

Since 2002-03, Cleveland has finished with 25 or fewer wins in seven different seasons, tied with the Minnesota Timberwolves for the most in basketball.

But those seven dreadful seasons have also yielded some generational talents in the NBA Draft, most notably LeBron James and Kyrie Irving, leading to eight seasons with 50 or more wins over that span, the most in the Eastern Conference and the fourth most in the NBA. 

In the three full campaigns since James left Cleveland for the second time, the Cavs have gone an NBA-worst 60-159, but fans in Ohio are hopeful that this season's 20-15 start is evidence that those lean years have produced enough talent to fuel a franchise turnaround yet again.

Last season the Cavs accrued 34 losses before earning their 20th win, but their improvement runs even deeper. 

Cleveland has improved in almost every significant statistical category, but the growth on defense has been dramatic. Last year's squad had one of the league's five worst defenses, allowing 112.1 points per 100 possessions. This year, the Cavaliers are allowing 102.2 points per 100 possessions, the third-best mark in the league and the top in the East.

When combined with an offense that has shown incremental improvement, the Cavaliers have a net rating of +5.2 per 100 possessions, the fourth best in the NBA and ahead of fellow Eastern contenders like the Brooklyn Nets, Miami Heat and reigning champion Milwaukee Bucks.

All of this has come with Cleveland facing the NBA's third-toughest schedule so far, with an average opponents' win percentage of .526. 

While some predicted that the Cavs' hot start would fizzle out into another losing season, the team has maintained its wining ways through nearly half the season and looks to be in position to continue.

Despite playing in a division with the Bucks and surprisingly good Chicago Bulls, Cleveland's remaining schedule is the easiest in the NBA by opponents’ average win percentage, with a majority of the upcoming being played at home.

Rookie Evan Mobley, selected with the third overall pick in July's draft, has been the catalyst for Cleveland's transformation this season. The 20-year-old big man is fourth in rookie scoring at 14.3 points per game but has made an all-around impact more typical of a veteran than a player who was in high school two years ago.

The Cavs' selection of the seven-footer Mobley was criticized by some pundits as redundant after the franchise had just re-signed center Jarrett Allen to a contract worth $100million earlier last offseason. 

Mobley and Allen have answered critics by forging one of the most formidable frontcourt defenses in the NBA. When Mobley and Allen are on the court together, the Cavaliers have a preposterous 95.3 defensive rating and opponents are shooting just 40.7 percent from the floor.

In a league that continues to downsize, Mobley has started most of his games at power forward, but the Cavs have found they do not sacrifice much offensively because their young star is so skilled and versatile.

While Allen has thrived around the rim this season, Mobley has the skill and athleticism to play everywhere, spacing the floor and keeping the ball moving on offense while smothering all sizes of players on defense.

Credit is due to head coach J.B. Bickerstaff, who identified early on that his frontcourt players were talented enough that he could buck the league's small-ball trend by starting his twin towers lineup.

Bickerstaff also had the courage to tell Kevin Love, the team's highest-paid player, that he would be coming off the bench. Love, who has been openly disgruntled about Cleveland's losing records in previous years, has embraced his new role and has seen a resurgence in both enthusiasm and efficiency.

The Cavaliers have been so pleased with Bickerstaff's leadership, in fact, that the parties agreed to a multiyear extension last week that keeps him under contract through the 2026-27 season.

Bickerstaff, Mobley and Allen – who is still just 23 years old – form a foundation that Cleveland intends to build upon for the next several years.

The Cavs' other unquestioned franchise staple is point guard Darius Garland, who has continued to improve in his third year. Garland is on pace for career-highs with 19.5 points per game, 7.3 assists per game and 47.9-percent shooting from the field. 

Garland has been forced to shoulder a heavy offensive burden and will be an even more vital player as the Cavs entered the second half of the season.

Backcourt mate and last year's leading scorer Collin Sexton was lost for the season after tearing cartilage in his left knee on Nov. 7.

Sexton's injury forced veteran guard Ricky Rubio into a more prominent role, a combination that worked very well for several weeks until Rubio suffered a torn anterior cruciate ligament in his left knee on Tuesday, ending his season as well.

The thinning of their backcourt led to the Cavs trading for the 16th-year veteran as an experienced floor general just before the calendar flipped to 2022.

It looks as if the 2021-22 season will be one of attrition, and a lack of depth may ultimately prevent the Cavaliers from maintaining an elite point differential in the East. But with a team so young, the franchise would have to be pleased just to play in the postseason again.

Going forward, however, Cleveland faces a crossroads decision in the coming offseason with Sexton's contract. The fourth-year guard is in the final year of his rookie deal, and the front office must decide if the Garland-Sexton backcourt combination is the best long-term option.

Sexton averaged 24.3 points per game last season, making it seem like offering him an extension would be the obvious solution. But high-scoring numbers like that typically demand a maximum contract – in this case, $173million over five years.

Garland and Sexton both stand just 6ft1, creating some flexibility issues. Since the latter was drafted in 2018, the Cavaliers have been wiling to live with a defensive liability in the backcourt as they focused on collecting talent and developing young players.

But now that Cleveland appears ready to make a run at the playoffs, more serious questions must be answered.

During Sexton's four-season tenure, the Cavs have allowed a staggering 115.5 points per 100 possessions while he is on the court versus 107.2 when he sits.

And despite Sexton's impressive scoring numbers, Cleveland's offensive numbers while he his on and off the court are virtually identical – over a sample size of over 12,000 minutes.

Paying Sexton long-term could lock in a future where the Cavs have the league's smallest backcourt and largest frontcourt, making them vulnerable to perimeter shot creators with size, the kind that has proven to be invaluable in postseason play.

All of that said, any team would be foolish to surrender a talented scorer like Sexton for nothing. A small-market team like Cleveland would be outright negligent. He is likely to get his extension, especially with the entire core being so young.

Garland, Sexton, Mobley and Allen have played less than 120 minutes on the floor together, and Cleveland's brass is likely to want to see them grow a bit more together.

Plus, teams in markets that are not free agency destinations simply do not have the luxury of being so choosy about trying to construct the ideal roster.

Although this Cavs team has some quirks that might project into a playoff ceiling in the future, Cleveland's front office has organically built a fun team – and one that appears to be a winner.

That is something the Cavs haven't done without LeBron James since last century.

Dan Biggar fears a "huge step backwards" if there are no crowds allowed at matches moving into 2022.

While crowds at sporting events have yet to be capped in England, matches in Wales and Scotland are now limited when it comes to capacity, amid a sharp rise in coronavirus cases.

Wales' first minister Mark Drakeford has not put any timescale on when the restrictions will be lifted, with the Six Nations set to start on February 5.

Scotland will formally review their measures on January 11, while France – where over 18,000 people were in hospital with COVID-19 as of December 30 – has imposed restrictions on travellers from the United Kingdom, with their government insisting that all sportspeople must be fully vaccinated by mid-January in order to enter the country.

Italy, likewise, is experiencing unprecedented levels of new recorded cases of the virus as the Omicron variant spreads across Europe.

But Wales fly-half Biggar believes banning spectators would be a frustrating move that will only damage the game.

"It would be a huge, huge step backwards if there are no crowds moving forwards for clubs and the Six Nations which is obviously such a showpiece event," he told reporters.

"You saw it in the autumn, getting crowds back. Everyone coming to games now has to have a passport, they'll be double or triple-jabbed, and it's an outdoor event so I don't see why they wouldn't be allowed in.

"As long as it's safe, that's the most important thing.

"I hope for an event like the Six Nations and for the game up and down the UK moving forward we get some sort of sensible outcome.

"As long as everyone is safe and jabbed then I think it makes sense to keep crowds in. I think you would have seen a different [Northampton against Harlequins] game if the stadium had been completely empty.

"We played a lot of games with no crowds but if you look at the first handful of games they almost felt like training games.

"It felt like it did not really matter whether you won or lost because it felt like a training match and like the intensity was knocked out of it. You lose any advantage of playing at home and bits and pieces like that.

"I think it would be a huge step backwards if crowds were to go. I think the rest of the lads in Wales are pretty frustrated with it. That's normal frustration isn't it?

"We are probably getting into different things with politics now but I think everything should be aligned."

Wales, the defending Six Nations champions, start their campaign against Ireland on February 5, with their first home game scheduled for February 12, against Scotland.

Rajon Rondo has reportedly been traded to the Cleveland Cavaliers by the Los Angeles Lakers.

The Athletic's Shams Chanaria reported the two sides had agreed to a deal to give the Cavs crucial backcourt help following an injury to Ricky Rubio.

Rubio suffered a torn anterior cruciate ligament in Cleveland's game with the New Orleans Pelicans on Tuesday.

He had played a critical creative role for the Cavs, who are fifth in the Eastern Conference at 20-15. His 6.6 assists per game rank 15th in the NBA.

Rondo, 35, will look to help fill the void having received limited playing time for the Lakers this season.

His average of 16.1 minutes per game is the lowest of Rondo's career, which is in its 16th year.

Unsurprisingly given his minutes, Rondo is averaging career-lows in points per game (3.1) and assists (3.7) while he is shooting at a career-low 32.4 per cent from the field.

Simone Biles is prouder of the mental health lessons she gave the world with her Tokyo Olympics withdrawal than any of the medals she has won.

The United States star withdrew from four individual events for which she had qualified after pulling out of the women's team competition after just one rotation in Japan in late July.

Biles cited a need to focus on her mental health as she chose not to contest the individual all-round, vault, uneven bars and floor exercise finals.

But she returned to action emphatically as she won the bronze medal in the women's balance beam final at the Games in early August, an achievement that she stated felt far more significant than her exploits in Brazil, in which she collected four gold medals in 2016.

Asked by MARCA if she was prouder of her achievements or the message sent by her withdrawal, the seven-time Olympic medallist said: "Most definitely the lesson that I gave the world in Tokyo, because nobody would have ever thought that would happen but everything that happened because of that has brought real good attention to mental health and the awareness that it brings.

"It was kind of a whirlwind of emotions, like 'oh my God, what's happening because I've trained five years for this?' 

"So, I was really sad, but I had to do what was right for the team and I knew that was the correct decision, but also what was right for me and my mental wellbeing.

"I am really proud that people are taking it more seriously. But I wish I could have gone out there and done a little bit more. But, with the cards I was dealt I'm not mad at the results."

Biles continued to reflect on mental health in sport as she pinpointed more athletes standing up to talk about a potentially sensitive topic as a positive for the future.

"I think it cost so much because everybody thought of us as entertainment and they feel entitled to our work and [wanted us to] just go out there and put on a brave face and compete," she said.

"But now you have these sports figures and heroes standing up for themselves and saying 'I'm not doing this competition, I don't get why it has an effect on you guys when I'm really the one that's being affected'. 

"To have that topic come to the forefront is really great, but it's sad that it's been silenced and forgotten for so many years and not as cared about. But, luckily we're bringing more attention to that."

Though she is proud of the impact of her experience in Tokyo, Biles admitted there are still some aspects of gymnastics that she is scared to perform.

"Some of the skills which I twist a lot on and flip a lot on, I am really scared to do just because of everything that happened," Biles added. 

"But, [my coaches] are really great every time I come into the gym if I want to play around. They make sure I'm doing all the proper steps, so they definitely make me feel a lot better."

While citing her coaches' help as a driving factor for her recovery, Biles also believes she would not have made it through the troubles in Tokyo without the help of her USA team-mates.

Despite a turbulent 2021, Biles remains happy as she continues on her indefinite break to rest and recover from a difficult year.

"What's next in my career right now is I'm obviously on a break," she concluded. "So, we have to see. I'm not sure if I'll continue with the sport. Right now, I think it's just relaxing taking quality time with family and with friends and just being normal for once.

"I think I'm happy with the way my life has turned out, especially starting gymnastics at six years old. 

"All I wanted was a college scholarship and I've been to five World Championships and two Olympic Games. So, I think I've achieved more than my wildest dreams, so I can't complain."

Inter forward Edin Dzeko has again tested positive for coronavirus, the club announced on Friday.

Dzeko was reportedly sent home as a precaution from Inter's first training session back following the mid-season break after exhibiting cold symptoms on Thursday.

It was not known at that time whether it was COVID-19, but Inter confirmed the following day that three players, including Dzeko, had tested positive for the virus.

Martin Satriano and Alex Cordaz make up the trio of coronavirus absentees, with the Serie A leaders stating the three players are already in self-isolation at home and following the government's health guidelines.

This is the second time Dzeko has contracted the virus, having tested positive in November 2020 when at Roma.

Dzeko has led the line effectively with Lautaro Martinez this campaign, scoring eight times and assisting three goals in 18 Serie A outings.

Indeed, the Bosnia-Herzegovina international has comfortably exceeded his expected goals (xG) total of 5.89, while only strike partner Martinez has found the net more often for Inter this season (11).

Inter head into early January in control of Serie A, sitting four points clear at the summit, with their next game against Bologna scheduled for next Thursday.

The Golden State Warriors won a potential Western Conference Finals preview on Christmas Day and will look to mark the New Year by prevailing in another on the road at the Utah Jazz.

Golden State are tied for the best record in the NBA at 27-7 and the Warriors beat the team level with them, the Phoenix Suns, in Arizona on their previous away trip.

Since then, the Warriors have paid the price for a slow start in a narrow home defeat to the Denver Nuggets and seen a return clash in Colorado postponed due to a COVID-19 outbreak within their opponents' camp.

That at least gave the Warriors the chance for extra rest ahead of a meeting with the red-hot Jazz, who are third in the conference with a 25-9 record and riding a five-game winning streak.

They maintained their winning run without star point guard Donovan Mitchell, who has missed the previous two games with a strained back, Rudy Gobert leading Utah to a 120-105 victory over the Portland Trail Blazers last time out.

Utah will hope Mitchell returns to set up a compelling matchup with the NBA's three-point king Stephen Curry, who became the first man to reach 3,000 career three-pointers in that defeat to the Nuggets.

Curry will predictably shoulder the scoring burden for the Warriors as the long-awaited return of his 'Splash Brother' Klay Thompson from a two-season-long absence grows closer.

With Draymond Green and Jordan Poole both in the NBA's coronavirus protocol, it may have to be a one-man show in Salt Lake City if the Warriors are to prevail, Golden State having scored under 90 points for the first time this season in the loss to Denver.

PIVOTAL PERFORMERS

Golden State Warriors – Andrew Wiggins

Minus Curry's chief facilitator in Green and emerging young guard Poole, the primary support for the Warriors' main man must come from Wiggins.

The former number one overall pick has finally found a home with the Warriors and leads the team with an effective field goal percentage of 56.6.

Utah Jazz – Rudy Gobert

The man known as the Stifle Tower is enjoying a magnificent season.

France international Gobert leads the league in rebounds per game (14.9) and field goal percentage (71.6), while he is second for blocks per game (2.3). However, given Curry's tendency for feasting on centers, the Jazz will surely try to avoid getting him isolated on the Golden State star.

KEY BATTLE – Can Mitchell master Chef Curry?

Mitchell has been sensational when on the court this season. He is averaging 25.4 points per game while his plus-minus per game of 7.6 is the eighth-best in the NBA.

However, both those numbers are inferior to Curry, who is second in the league with 27.7 points and leads the NBA with an average plus-minus of 11.7.

Few players can claim to have come anywhere close to matching Curry's overall influence this campaign. Mitchell's ability to do so on New Year's Day could have a huge bearing on who eventually claims the one seed in the West.

HEAD-TO-HEAD

The Warriors have won their past two games against the Jazz, though both of those triumphs came at home. Golden State's most recent win in the Beehive state came back in October 2018. 

Fiorentina have agreed a deal to sign Jonathan Ikone from Lille for a reported €15 million fee.

Ikone played 150 games for Lille across all competitions, scoring 16 goals and assisting 26 times as he helped Les Dogues to the Ligue 1 title last term and top spot in their Champions League group this campaign.

The 23-year-old, known for his versatility across the frontline, had two years left to run on his current contract but has signed for Fiorentina on a reported five-year deal.

Lille allowed Ikone to train with the Serie A outfit in preparation for the move, which will officially go through on Monday when the transfer window opens.

The arrival of former Paris Saint-Germain man Ikone furthers speculation as to the future of Viola striker Dusan Vlahovic, who has been linked to numerous clubs among Europe's elite.

Reports suggest Manchester City are among the suitors for Vlahovic, who enjoyed a record-equalling 2021 as he netted 33 times to match Cristiano Ronaldo's Serie A haul in 2020.

Gunnar Nordahl's 36-goal year for Milan in 1950 marks the last time any player scored more than 33 in the Italian top flight across a calendar year.

Whether Ikone slots in behind Vlahovic or has been signed as a replacement remains to be seen, however, Fiorentina's acquisition will offer Vincenzo Italiano an alternate attacking option in his forward line.

Ikone ranks far above any of his Lille team-mates for dribbles attempted this Ligue 1 campaign (61), with Jonathan Bamba in second with 44, while only Jonathan David (17) has created more chances than the France international (16).

James Harden felt "carelessness" on rebounds proved costly for the Brooklyn Nets as they were beaten by the Philadelphia 76ers on Thursday.

Despite the return from COVID-19 protocols of Kevin Durant, who put up 33 points, the Eastern Conference Leaders lost 110-102 at Barclays Center.

The Nets responded to falling behind in a high-scoring first quarter to lead by seven points in the third, Harden assisting Durant for two three-point jumpers in the space of 23 seconds.

However, Philadelphia mounted a late comeback before easing to a win that saw them improve to 19-16 for the season.

Harden tied Durant as top scorer for the Nets as he recorded a triple-double of 33 points, 14 rebounds and 10 assists. It was his sixth of the season, a tally surpassed only by the Los Angeles Lakers' Russell Westbrook (eight).

Still, he was frustrated that they let their third-quarter lead slip by giving up too many opportunities.

"They've got more than enough talent to have a really good game after a really good first quarter," he said.

"We climbed back into the game, did a really good job locking down defensively and just doing what we were supposed to do. Obviously, 16 points in that second quarter, we got a chance in that third quarter, went up by eight or something, but we allowed them to get offensive rebounds and more shots in general.

"The rebounds were] a little bit of carelessness, a little bit of decision-making. I had a couple I wish I could have got back. That's the game right there. You talk about it in training camp, not allowing the opposing team to get so many more shots than us. Tonight was a case of that."

Next up for the Nets is a home game with the Memphis Grizzlies on Monday before they head to the Indiana Pacers next Wednesday, when Kryie Irving could make his first appearance of the season.

Irving, who was back on the practice court this week, is unvaccinated against COVID-19 and so is only able to play in road games due to New York City regulations.

Harden said of his team-mate: "He looked like Kyrie: elite. The same Kyrie. We're happy to have him back and we've got to get him on the court."

Joel Embiid bossed the Eastern Conference-leading Brooklyn Nets despite the return of Kevin Durant as the Philadelphia 76ers center scored 34 points in a 110-102 win on Thursday.

Embiid finished with 34 points, including three triples, six rebounds, three steals and one block as tension boiled over between him and Durant who exchanged words late in the game and gestured demonstrably after the final buzzer based on their history.

Durant returned from protocols with 33 points, seven rebounds and four assists, while James Harden recorded a triple-double with 33 points, 14 rebounds and 10 assists.

The 76ers got home in a tight encounter with a 26-20 final quarter helping them to their third straight win and fourth in a row on the road.

Brooklyn's record moves to 23-10 while the 76ers improve to 19-16 as the east heats up.

Champions clinch fifth win in a row

Giannis Antetokounmpo and the Milwaukee Bucks were in the mood with a 136-118 victory over the Orlando Magic. The 2021 NBA Finals MVP scored 33 points with 12 rebounds, five assists, two steals and two blocks for the reigning champions.

Jrue Holiday (25 points, five rebounds, seven assists) and Khris Middleton (22 points, three triples, six assists) made valuable contributions as the Bucks claimed their fifth consecutive win to improve to 24-13.

Bradley Beal returned from protocols with 29 points, six rebounds and 10 assists while Kyle Kuzma had 25 points with 10 rebounds as the Washington Wizards won 110-93 over the Cleveland Cavaliers. Kevin Love top scored for the Cavs, who were without Darius Garland in protocols, with 24 points and 11 rebounds.

Mills errant from range

Australian guard Patty Mills had an unhappy time in the Nets' loss to the 76ers, shooting one of eight from beyond the arc and 20 percent from the field for five points.

Title-winning NBA head coach Doc Rivers is "feeling good" despite entering the league's health and safety protocols on Thursday.

Dan Burke, who will step in as the Philadelphia 76ers acting coach in Rivers' absence, said the 60-year-old was in good health and spirits while isolating.

Rivers is one of seven NBA head coaches who has entered protocols, amid the rising COVID-19 surge around the league.

"He says he feels good. He's not the least bit worried," Burke told reporters about Rivers.

"If there's anybody who just takes things in stride and keeps it real and keeps it relative, it's Doc. That's the lead we've got to follow."

On Thursday, the 76ers are due to play the Eastern Conference-leading Brooklyn Nets who will be bolstered by the return of Kevin Durant after clearing protocols.

Rivers, who guided the Boston Celtics to the 2008 NBA title, has helped the 76ers to an 18-16 record this season.

Draymond Green has questioned the NBA as he felt the Denver Nuggets will gain an advantage after the cancellation of their clash with the Golden State Warriors.

The Warriors were set to face Denver in the second of a two-game showdown on Friday, but a coronavirus outbreak within Michael Malone's camp has forced the game to be called off.

The Nuggets were left without the necessary eight players for the clash to go ahead, while coach Malone entered the league's health and safety protocols on Thursday along with other staff members, including two assistant coaches, according to reports.

On the same day, forwards Jeff Green and Zeke Nnaji and guard Bones Hyland had also entered protocols, with injuries to several Nuggets players leaving them short-handed.

But Warriors forward Green, who was absent due to protocols for Tuesday's 89-86 loss to the Nuggets, was left frustrated by the postponement as he thinks his side will be disadvantaged by the decision.

"How do you continue to cancel games when you've implemented rules to prevent this from happening?" Green posted to Twitter. "Is that not a competitive advantage for other teams?

"The guys we didn't have due to the protocol list played no role in Tuesday's loss? Pick a side but don't straddle the fence.

"So when the game is rescheduled (which will probably take a day away from our "break"), we will play them at full strength... But they got to sneak a win when we weren't at full strength, only two days ago??? Let's make it make some sense here."

It is the 11th game to be postponed this season for coronavirus-related issues, though Green is worried about the scheduling issues it may cause.

The Golden State star added: "Not to mention, this will more than likely add a back to back to our schedule, which is also advantage Denver."

In Malone's absence, assistant coach David Adelman will reportedly serve as acting head coach for the Nuggets.

Malone is the seventh NBA coach to enter the protocols, joining Doc Rivers (Philadelphia), Frank Vogel (Lakers), Monty Williams (Phoenix), Billy Donovan (Chicago), Chauncey Billups (Portland) and Mark Daigneault (Oklahoma City).

The Warriors are next due to be in action against the Utah Jazz on Sunday when Denver face the Houston Rockets.
