Boston Celtics head coach Joe Mazzulla says point guard Derrick White is OK after suffering a worrying neck injury early in Saturday's 122-106 win over the Charlotte Hornets.

White exited the game in the first quarter when he inadvertently collided with teammate Marcus Smart as he bent over to pick up the ball after P.J. Washington attempted a steal.

The collision led to White falling to the ground, clutching his head and neck, with the Celtics later ruling him out of the game with a "neck sprain".

"He's good," Mazzulla told reporters. "I haven't gotten a report back but he's OK, I spoke with him in the locker room."

In White's absence, Malcolm Brogdon played 31 minutes off the bench, contributing 30 points on 11-of-17 field-goal shooting with three rebounds and three assists.

The former Indiana Pacers point guard, who joined the Celtics in July, has added good scoring output lately, averaging 20 points over the last five games.

"It obviously changed our rotation as we were a man down, but I thought Malcolm was great tonight," Mazzulla said.

"He's a guy that is adjusting to playing on our team. He shows tremendous humility and patience. Tonight was big for him. He really helped our team and was really selfless. I'm happy for him."

MVP candidate Jayson Tatum led the way for the Celtics, who recorded their sixth straight win to improve their NBA-best record to 32-12, with 33 points.

Tatum scored 17 points in the third quarter as the Celtics responded to a 66-62 half-time deficit, to lead by 10 at the final change.

The Celtics small forward shot 12-of-27 from the field with four triples along with nine rebounds and six assists.

Mazzulla praised Tatum, who is learning how different teams are guarding him to develop his consistency.

"He's done a really good of developing an awareness, because it changes night to night and quarter to quarter," Mazzulla said. "He's done a nice job of building an awareness to what the coverage is and having a solution for that."

Everton manager Frank Lampard says the club's tense off-field situation had no impact on him and his players in Saturday's 2-1 home loss to Southampton where they let a first-half lead slip.

The defeat worsened the Toffees' relegation concerns, having won only once in their past eight games, leaving them 19th ahead of only Southampton on goal difference. Everton's last league victory was on October 22.

That situation has created a tense environment, with Everton's board of directors opting not to attend Saturday's fixture due to a "real and credible threat to their safety and security".

Disgruntled Everton fans staged a 'sit-in' protest after the game against how the club has been run.

"I'm completely focused on what we're doing on the pitch," Lampard told BBC. "The off-field noise is there but the things we can control as staff and players is on the pitch - and today we got beaten.

"It's a difficult period. There is so much passion at this club for the right reasons, everyone wants the best for the club.

"Of course, over the years we've come in a direction where we were in a relegation battle last year and again this year."

Everton had taken the lead in the 39th minute from Amadou Onana, but the Saints responded with James Ward-Prowse equalizing shortly after half-time, before netting a trademark free-kick for the winner in the 78th minute.

"It's obviously difficult and disappointing, especially when you go 1-0 up," Lampard said. "It's a tough game, there's a lot of tension for both teams I think.

"We deserved to be 1-0 in the first half with the passion in our game. It wasn't a tactical game, it was more of a fighting game.

"We showed spirit and then an early goal in the second half changes the tone of the game. We came back, created some things, we hit the bar but then, typically at the moment, we concede a free-kick and it goes in our net.

"Obviously, it's disappointing. It was a big game for us and we lost."

Hayden Buckley finished the third day at the Sony Open in Hawaii with an eagle to claim a two-stroke lead from David Lipsky, Ben Taylor and Chris Kirk on Saturday.

Buckley carded a six-under-par round of 64 to be 15-under overall, managing two eagles on the third day along with three birdies and a bogey at Waialae Country Club.

The American sunk a 28-foot birdie putt on the eighth hole, before he moved into the lead buoyed by an excellent back nine where he nailed a 133-yard hole-out eagle on the 10th hole along with another on the 18th aided by a pinpoint approach.

Halfway leader Kirk slipped after a third-day 68 which started with a double bogey on the first hole, although he expertly produced a hole-out birdie from the bunker on the 14th to stay in contention.

Lipsky had an up-and-down round that included seven birdies and three bogeys, while Englishman Taylor birdied four of his final six holes to be tied for second at 13 under.

Andrew Putnam shared the round of the day with Nick Taylor, both carding eight-under-par rounds of 62, with the former moving to 12-under overall.

Putnam, who managed a career-high 10 birdies, is tied with Si Woo Kim, who had a strong third round with seven birdies in his 64.

Will Gordon and Nate Lashley are a further shot back at 11 under, while J.J. Spaun's third-round 71 saw him drop to well off the pace and nine under.

Two-time major winner Hideki Matsuyama enjoyed his best round at the Sony Open with a 65, leaving him at eight-under overall.

The San Francisco 49ers advanced to the Divisional round of the NFL playoffs with an 11th straight victory on Saturday, recovering from a rocky first half against the Seattle Seahawks in some style.

The 49ers, led by rookie quarterback Brock Purdy and backed up by a league-leading defense, had twice beaten NFC West rivals the Seahawks this season and clearly had momentum on their side heading into their Wild Card matchup.

But a 41-23 win at Levi's Stadium was not initially as straightforward as many would have imagined – or as the final scoreline suggests, as Seattle scored 17 second-quarter points.

Purdy trailed at halftime for the first time despite San Francisco making the stronger start. Kenneth Walker ran in for the Seahawks after Christian McCaffrey had caught the opening touchdown pass, then Geno Smith – another playoff debutant but nine years older than Purdy – connected with D.K. Metcalf for a 50-yard score.

The 49ers got back on track with a TD drive to start the second half, though, and their defense belatedly came to the party when Charles Omenihu forced a fumble that was recovered by Nick Bosa.

After zero turnovers and zero penalties in the first half, the Seahawks soon unravelled, unable to respond either when Purdy superbly sought out Elijah Mitchell in the endzone or when a pass to Deebo Samuel gave him space to race away for a 74-yard TD.

Smith swiftly threw an interception as Seattle waited until after the two-minute warning for their first score of the second half, while Purdy showed no signs of slowing his remarkable rise as he finished with 332 yards and three TDs through the air in his sixth straight win to start his career.

The 2022 NFL Draft's 'Mr Irrelevant' has extended the 49ers' winning streak to 11 – tying their third-longest of all time – and continues to look capable of carrying one of the league's most talented rosters all the way in this postseason.

Inter midfielder Roberto Gagliardini looks set to leave San Siro at the end of the season after claiming he needs more regular football.

The 28-year-old former Atalanta player, who has been capped by Italy, has started only two Serie A games this season for the Nerazzurri.

One of those came on Sunday when he helped Simone Inzaghi's team to a 1-0 win against Hellas Verona, playing the full game.

Gagliardini has featured off the bench six times in the Italian top flight this term, but he wants greater and more consistent involvement, and that will probably mean his future lies elsewhere.

He was praised by coach Inzaghi on Saturday, commended for an "excellent" display, but Gagliardini's contract expires at the end of the campaign and all signs point to a parting of ways during the Italian summer.

Bergamo-born Gagliardini told Sky Sport: "I'm no longer willing to have this playing time. I'm 28 years old, and I want to prove a lot.

"I'm more ready than a few years ago, because these years have seen great growth for me, in my head and in the reaction to the difficult moments, so in June I will make my decisions."

Gagliardini was a Serie A winner with Inter two years ago, but he was only a bit-part player in that success, starting four times and coming off the bench on nine occasions.

Responding to his player's comments, Inzaghi said in a press conference: "The important thing is that he does well on the pitch.

"He's highly regarded by everyone, he's a serious professional who works very well. He's had a few minor problems in the last year, but he's always gritted his teeth, guaranteeing his contribution."

Lautaro Martinez believes Inter can still catch runaway leaders Napoli in the Scudetto race but recognises the Nerazzurri cannot afford mistakes during the second half of the season.

The Argentina forward was the match winner against Hellas Verona on Saturday, with a third-minute strike – his ninth goal of the campaign – enough to secure a narrow 1-0 victory at San Siro.

Simone Inzaghi's side subsequently moved level with third-placed Juventus, although they still trail Napoli by 10 points after 18 matches.

Nevertheless, Martinez is confident the Nerazzurri have plenty of time to chase down the Partenopei.

"We knew that this would be a game like this, tough, as Verona man-mark all over the pitch," Martinez told Sky Sport Italia. "We scored early and then did what we had prepared. It was important to get all three points today.

"It is possible [to catch Napoli] as there is a long way to go yet. But we have to make no more mistakes; we need to get every point going or they will be too far away."

The Verona match was Inter's fourth in the space of 11 days, a sequence that began with a victory over Napoli.

Most recently, on Tuesday, Inter had been taken to extra time by Parma in the Coppa Italia, and Inzaghi felt the quick turnaround took its toll.

"We were coming off 120 minutes played on Tuesday, but the team remained sharp," Inzaghi said. 

"We scored early and then, despite a little tension in the closing stages, we remained solid and focused without suffering much against a Verona side that could cause us problems.

"I was concerned by our fitness levels with [Hakan] Calhanoglu and [Nicolo] Barella, who pushed themselves so hard to be available today. 

"They were in doubt until yesterday, while [Henrikh] Mkhitaryan, [Roberto] Gagliardini and [Kristjan] Asllani really helped out in these games with their midfield performances."

Mikel Arteta is making memories at Arsenal he says he will never forget as he saluted the Gunners' "incredible dressing room" ahead of the North London derby against Tottenham.

Following a blistering start to the season, in which they have won 14 of their first 17 games, Arteta's side can move eight points clear at the Premier League summit with victory over their bitter rivals on Sunday.

Arteta endured a testing start to life at Emirates Stadium, but the pendulum has certainly swung in his favour this term, and he is enjoying himself now.

"It's just an incredible dressing room. It's just a joy to work with [the players] every single day," said Arteta, who won the Premier League's Manager of the Month award for December.

"Some of the things that we've done together, I'll probably never be able to do them with any other team or with any other group.

"Especially on match days and the things that we do together, that will stay in my brain for the rest of my life."

The maturity of this young Arsenal team has particularly impressed Arteta, who has noted the way his relationship with the players has changed this season.

"[The players] are certainly more mature," he said. "I think the demands have changed as well and my role and what they, in my opinion, need from me is different as well.

"And that's why we always have to be evolving and trying to be ahead of what is coming, to give to the players and the rest of the staff what is going to make everything click to be more efficient and to win more games."

On the pitch, that has translated not only to better results but also better performances.

Arteta said of the changes at Arsenal: "We win more games, which is the most important thing and the thing that changes everything, and I think we play better.

"We deserve to win in the games that we have won, and probably that's the most relevant thing."

Lautaro Martinez scored the only goal as Inter made hard work of a 1-0 win over struggling Hellas Verona at San Siro.

Though the team effort was far from convincing, the Nerazzurri's in-form Argentina forward struck early to secure the narrow victory that moves them level on points with third-placed Juventus in Serie A.

Martinez has now netted three times in four appearances since his national team's World Cup success, while he took his league tally for the campaign to nine goals.

Meanwhile, Inter maintained their record of having never lost a top-flight match against Verona on home soil, where they have won each of their last eight games.

Inter broke through after just three minutes when the ball fell kindly for Martinez following Henrikh Mkhitaryan's promising burst into the Verona penalty area, and the striker neatly guided it into the far corner.

No side have scored more first-half goals than Inter in Serie A this season, and they looked to build on their strong start, Martinez heading straight at Lorenzo Montipo from Roberto Gagliardini's cross.

Referee Michael Fabbri waved away a penalty appeal from the hosts just before the break, despite Fabio Depaoli appearing to deflect Mkhitaryan's shot behind with his arm.

Inter thought they had doubled their advantage in the 63rd minute when Martinez brilliantly dinked the ball over the advancing Montipo, only to be denied for an earlier foul on Pawel Dawidowicz.

Winless in their previous 22 clashes with Inter since a 1-0 victory in February 1992, Verona went close to an equaliser when Sulemana's low drive from a tight angle called Andre Onana into action with 20 minutes remaining.

Substitute Kristjan Asllani almost put a seal on victory with a spectacular long-range effort, but Martinez's early strike proved enough for the hosts.

Stefano Pioli ordered Milan to cut out "trivial mistakes" after a 2-2 draw at Lecce left the Rossoneri nine points behind runaway Serie A leaders Napoli.

Last season's champions trailed Lecce 2-0 after 23 minutes on Saturday, before Rafael Leao and Davide Calabria hauled them back to level terms.

An exciting final 20 minutes could have brought a winner for either team, yet there were to be no more goals, and while the point nudged Milan up to second place, that gap to Napoli will be difficult to overcome.

Head coach Pioli told DAZN: "In the first half, we missed everything we could possibly miss. We made unforced mistakes and the match became more difficult."

Theo Hernandez turned a cross from Federico Di Francesco into his own goal to give Lecce a third-minute lead, and Pioli said after the game: "We need to be more clear-headed."

Milan's haul of 38 points from 18 games points to a sturdy start to their title defence, with the caveat Napoli have made a roaring opening to the season and have won 15 of their opening 18 matches.

Pioli said: "We are in line with last season, but it is also true that in this phase we are getting much less than we would like. We can do better and avoid trivial mistakes.

"We have to recover our principles of play and do it continuously."

Leao has had a goal involvement in each of Milan's last four league games, the first time he has had such a run, and his season's total of 13 involvements (eight goals, five assists) in 17 appearances is five ahead of where he was after the same number of matches in 2021-22.

Pioli denied the approaching Supercoppa Italiana game against Inter was a distraction to Milan.

That trophy game is coming up on Wednesday, and Pioli said: "It's a straight match against a great opponent, so we'll do everything to be ready."

He hopes to have Ante Rebic available for that game in Riyadh after recent muscle injury trouble, and Zlatan Ibrahimovic could also be in line for a return before long, the Milan boss added.

Ibrahimovic has yet to play this season, having undergone knee surgery at the end of the Scudetto-winning campaign.

Marcus Rashford hit the winner and played a part – some might say – in Manchester United's first goal as the Red Devils beat City in Saturday's derby.

The in-form England international moved into early-career Cristiano Ronaldo territory by scoring in a seventh consecutive game for United, who have won nine in a row across all competitions.

Elsewhere in the Premier League, Liverpool's campaign continued to unravel as they were battered 3-0 at Brighton and Hove Albion, and their neighbours Everton remain in deep relegation trouble after a home loss to fellow strugglers Southampton.

Another derby saw Nottingham Forest get the better of Leicester City, with Steve Cooper's team beginning to get a foothold in mid-table.

With the help of Opta data, Stats Perform examines key statistics from the Saturday's standout Premier League games.

Manchester United 2-1 Manchester City: Making his Marc again

Rashford has been a shining light for United since returning from the World Cup, scoring in all seven games for Erik ten Hag's team.

He is the first United player since Ronaldo in March-April 2008 to put together such a streak, while his run of goals in nine consecutive games at Old Trafford makes him the club's first player since Teddy Sheringham in September-November 2000 to enjoy that level of home form.

Bruno Fernandes got the equaliser, after an opener from City's Jack Grealish, with Rashford not flagged offside in the build-up after chasing the ball but not getting a touch prior to his Portuguese team-mate lashing past Ederson.

Rashford's close-range winner soon after, in the 82nd minute, was set up by Alejandro Garnacho, who at 18 years and 197 days became the youngest player to provide an assist in a Premier League Manchester derby.

City had just one shot on target, their joint-fewest in a Premier League match under Pep Guardiola.

Kevin De Bruyne set up Grealish's headed opener, reaching double figures in Premier League assists for a fifth season, with only Cesc Fabregas (6) doing so in more campaigns, but that was of no consolation as City saw their title hopes dented.

Brighton and Hove Albion 3-0 Liverpool: Worth the wait for Seagulls

Jurgen Klopp's reaction summed it up, when he said: "I think everybody with a Brighton shirt on or a Brighton heart enjoyed the game a lot and I don't think anybody with a Liverpool heart enjoyed it for a second."

This was a horror show for the Reds, suffering their first league defeat at Brighton since January 1961 (3-1). Liverpool had gone 10 unbeaten away to the Seagulls in the league before Solly March's double and Danny Welbeck's sublime goal left them reeling.

Liverpool have suffered six defeats now in 18 games in the competition this term, three times as many losses as they incurred in the entire 2021-22 Premier League campaign. It was a fifth league loss away from Anfield, their worst season total since also losing five in 2017-18. This season is not yet at its halfway point for Liverpool, who sit ninth.

This game kicked off at 3pm locally. It was the first Saturday 3pm league game Liverpool have lost since going down 2-0 to Hull in February 2017, ending a 32-game undefeated streak in that slot.

March has four goals in his last four games, which is as many as he managed in his first 156 in the Premier League.

Everton 1-2 Southampton: Ward-Prowse piles on misery for Lampard

Sitting second-bottom now, Everton are having a dismal time of it under Frank Lampard's leadership, losing four league games in a row at home for the first time since a seven-game streak in 1958. They are winless in seven in the league, their worst run since an eight-game sequence under Rafael Benitez in October-December 2021.

Amadou Onana put the hosts ahead, becoming the fourth Belgian player to score for Everton in the Premier League, after Romelu Lukaku, Kevin Mirallas and Marouane Fellaini.

But Saints captain James Ward-Prowse then took over, netting twice including the 16th direct free-kick goal of his Premier League career, putting him just two behind David Beckham's competition record.

It was his 12th such goal in away games, more than any player has managed in the Premier League, and only Matt Le Tissier (44) has managed more away goals in the Premier League era for Southampton than Ward-Prowse's haul of 28.

Nottingham Forest 2-0 Leicester City: Johnson's derby delight

Brennan Johnson hit both goals in the East Midlands showdown, doubling his Premier League tally for the season and becoming the second-youngest Forest player to score twice in a Premier League game (21y 236d). Roy Keane, who struck a double against Leeds in December 1992 (21y 117d), remains the youngest.

Morgan Gibbs-White, at 22 years and 352 days, became the youngest to have two assists in a Premier League game for Forest.

Leicester are free-falling, with this a fourth consecutive league defeat. Remarkably, it is not yet their worst run of the campaign, having lost six in a row in August and September.

They have yet to win a point this season from a losing position, the only Premier League team to fail on that count.

Manchester City defender Manuel Akanji described the decision to not disallow Manchester United's first goal in Saturday's derby as a "joke".

Jack Grealish had seemingly set City en route to three points with his second-half opener, but Bruno Fernandes levelled in contentious fashion before Marcus Rashford clinched a 2-1 victory at Old Trafford.

City were furious with United's leveller because Rashford, who was offside, approached the ball but allowed Fernandes to take the shot.

The flag was initially raised to signal offside against Rashford, but referee Stuart Attwell overturned the decision having spoken to his assistant Darren Cann.

The fact Rashford opted against touching the ball and that he technically did not impede Akanji meant the England forward was not deemed to be interfering with play, therefore the goal counted.

Attwell's decision caused a stir on social media, with former professionals among those questioning the outcome, and Akanji is adamant it was the incorrect call.

"For me, the first goal is a joke that it's going to be allowed like this," he told the BBC.

"In that situation, I see Rashford is clearly offside, so I play him offside. He runs really to the last second and he stops when the ball is in front of him.

"He's right in front of Edi [Ederson] to score the goal and then he stops because Bruno is calling him from behind that he [Fernandes] is not in an offside position.

"I understand that he doesn't touch the ball, but he runs for like 30 metres, he's chasing the ball and then he stops. For me, it's clearly offside."

Defeat for City leaves them just a point above United and gives Arsenal the opportunity to extend their lead at the top of the Premier League to eight points if they beat Tottenham in Sunday's north London derby.

The Professional Tennis Players Association is committed to equal pay for men and women at grand slam level, according to the man who teamed up with Novak Djokovic to launch the organisation.

Vasek Pospisil, whose on-court doubles efforts helped Canada win the Davis Cup for the first time in November, said the PTPA would "fight for both sides" in its efforts to improve players' prospects throughout the sport.

The breakaway union has caused controversy, with the ATP and WTA, which run the men's and women's tours, adamant they already have significant player representation when it comes to making decisions in the best interests of tennis.

Djokovic quit as president of the ATP player council to become the figurehead of the PTPA, which was launched at the height of the pandemic during the 2020 US Open.

There was initial criticism of the PTPA when no women appeared to be involved.

However, Pospisil said at the time discussions were ongoing, and ahead of the upcoming Australian Open, its first executive committee was unveiled, consisting of four men and four women.

Joining Djokovic and Pospisil are Hubert Hurkacz and John Isner, plus WTA players Paula Badosa, Ons Jabeur, Bethanie Mattek-Sands and Zheng Saisai.

Pay has been equal at all the grand slams since 2007, when Wimbledon announced it would reward women the same amount it pays men.

Asked about equal pay at the four majors and the PTPA's position, Pospisil told Stats Perform: "From day one, we always knew that this would only be successful with the women, and that has always been our goal. And so we're really happy that we're gaining a lot of traction now on the women's side.

"Currently, there is equal pay at the grand slam level, I believe, so that's obviously amazing.

"It is a joint organisation, both men and women, and we'll do everything to fight for both sides.

"Obviously, they're separate tours. The WTA, ATP, and grand slams are joined, of course. So, the staff will have their hands full with trying to advocate for both sides.

"It's a unified player association for both men and women, and we're really proud of that and where we're going."

Those already involved, and those the PTPA will hope to attract, are being advised the union is aiming to bolster the rights – and at the bottom line, the earning potential – of all involved.

There is currently significantly more money on offer on the ATP tour than on the WTA circuit, which points to issues of inequality remaining in the sport.

It has been known in recent times for some high-profile tournaments, where tours converge, to pay its men's champion more than its title-winning woman. This is despite events on both tours being best-of-three-set matches, whereas in the slams women play best-of-three and men play best-of-five, a matter that has long been a trigger for equal-pay debate.

Pospisil believes the WTA has a "smart and passionate" group of eight on its ExCo and said the "energy was amazing" when the group met for dinner on Thursday in Melbourne.

"I just have such a good feeling after a few years of working on this," Pospisil said. "To finally be at the stage where we're ready to go, are launching, got everything we need, and we have amazing player board reps that honestly we couldn't be happier with."

Djokovic, a 21-time singles grand slam winner, is at the forefront, and Pospisil said the 35-year-old Serbian's role has been crucial.

"I feel like you need somebody that is at the top of the sport," Pospisil said. "So, I just think all the players and our organisation, we're very lucky that he's so supportive and that he's stuck his neck out and is fighting for what he believes in and what he believes is right."

Shakhtar Donetsk have confirmed an agreement with Chelsea for Mykhaylo Mudryk is "very close".

The Blues are widely reported to have seen an £88.5million (€100m) bid accepted by the Ukrainian side for the winger, seemingly leapfrogging London rivals Arsenal to the front of the queue.

Mikel Arteta's side were said to have made progress towards a deal of their own in recent days but have been left in the lurch following Chelsea's move.

In a statement, Shakhtar said: "Shakhtar president Rinat Akhmetov and Chelsea co-owner Behdad Eghbali discussed Mykhaylo Mudryk's transfer to Chelsea today.

"Parties are very close to agreeing on the player's transfer to the club."

Mudryk previously expressed a desire to move to Arsenal and has dropped several hints on social media this month, with the Premier League leaders thought to be his preferred destination.

However, that prospect may now be off the table unless the Gunners up their offer, with Chelsea firmly leading the chase.
