The New Orleans Pelicans will likely be without franchise player Zion Williamson for at least the next week after suffering a hamstring injury in Monday's 120-111 loss to the Philadelphia 76ers.

It was late in the third quarter when the injury occurred, with the Pelicans trailing 84-81, as Williamson pushed the ball in transition before sharply pulling up, holding his right hamstring.

He had 26 points on 10-of-12 shooting, adding seven assists and six rebounds in his 28 minutes before the incident, with the 76ers taking the fourth period 36-30 following his departure.

Speaking after the game, Pelicans head coach Willie Green confirmed the injury as a right hamstring strain.

"It was right at a pivotal moment in the game," he said. "We'll get some imaging and look at him and hopefully he's okay. It was a tough loss for us."

Williamson has played in 28 of the Pelicans' 37 games up to this point after missing the entire 2021-22 season, and had rediscovered his best form in December.

He averaged 29.8 points, 7.5 rebounds and 5.1 assists per game while shooting 61.3 per cent from the field during his 12 games in December, picking up the slack while team-mate Brandon Ingram has been sidelined.

Joel Embiid ended up as the star of the 76ers' win, scoring a game-high 42 points with 11 rebounds and five assists.

Monday's fixture between the Buffalo Bills and the Cincinnati Bengals has been officially suspended after Bills safety Damar Hamlin collapsed on the field and was taken away in an ambulance.

Hamlin, 24, had made a tackle on Bengals receiver Tee Higgins, and after briefly returning to his feet, he collapsed.

He remained down for over 10 minutes, and was seen receiving CPR before being loaded into an ambulance and taken to a local hospital.

All players and team personnel returned to the locker room and over an hour passed before the NFL decided to officially call off the rest of the night's proceedings.

A statement from the league confirmed Hamlin is in "critical condition".

It read: "Tonight’s Buffalo Bills-Cincinnati Bengals game has been postponed after Buffalo Bills' Damar Hamlin collapsed, NFL Commissioner Roger Goodell announced.

"Hamlin received immediate medical attention on the field by team and independent medical staff and local paramedics. He was then transported to a local hospital where he is in critical condition.

"Our thoughts are with Damar and the Buffalo Bills. We will provide more information as it becomes available.

"The NFL has been in constant communication with the NFL Players Association which is in agreement with postponing the game."

The game was called off halfway through the first quarter with the Bengals leading 7-3.

Monday's game between the Buffalo Bills and the Cincinnati Bengals has been temporarily suspended after a scary situation unfolded as safety Damar Hamlin collapsed and was taken off the field in an ambulance.

The incident occurred during the first quarter, after Hamlin made a tackle on Bengals receiver Tee Higgins. He briefly returned to his feet, before collapsing.

He remained down for over 10 minutes as ESPN's broadcast reported he was receiving emergency CPR before being loaded onto a stretcher and into a waiting ambulance.

The game was temporarily suspended with the Bengals leading 7-3, with both teams heading back to the locker room as they anxiously await an update on Hamlin's health.

New York Knicks All-Star Julius Randle believes his side are figuring things out defensively after smothering the Phoenix Suns 102-83 on Monday.

The Knicks began the season shaky on the defensive end, posting the seventh-worst defensive rating in the league during their 16 games in November, giving up 115.1 points per 100 possessions.

They were a different team in December, limiting teams to 108.2 points per 100 possessions for the third-best defense, and that included a five-game losing streak at the end of the month where they conceded at least 113 points in each defeat.

But after getting back on the right track with a 108-88 victory against the Houston Rockets on New Year's Eve, the Knicks held their second consecutive opponent under 90 points for the second time this season, illustrating how imposing they can be on that end of the floor when they are switched on.

Their back-to-back defensive masterclasses have boosted the Knicks to the eighth-ranked defense for the season, with every team ahead of them essentially already pencilled into the playoffs.

Against the Suns, Randle received MVP chants from the Madison Square Garden crowd as he led the way with a game-high 28 points (seven-of-18 shooting), a game-high 16 rebounds and an equal team-high six assists.

It was a great way to start January after he put up terrific figures of 28.3 points, 11.4 rebounds and 4.3 assists on 47.8 per cent shooting in December, rediscovering the form that made him an All-Star in the 2020-21 season.

Speaking to the media after the game, the man who has endured his fair share of criticism from Knicks fans said "it's good to be on the good side of The Garden", before breaking down what has been behind their strong form.

"Defensively, we had to get back to our ways," Randle said. "When we won eight in a row, the defensive end was big for us. We feel that rhythm and chemistry coming back on that end."

Randle also spoke about how the addition of point guard Jalen Brunson in the offseason has helped his game.

"Honestly, it’s a lot easier [to score this season]," he said. "I attributed a lot of that to Jalen [Brunson], obviously.

"Also [Immanuel Quickley], and our guards… I’m not having to work as hard to get buckets or score. So, the game is a lot easier on my body."

When asked if he has put any thought into a potential return to All-Star Weekend, Randle said he is hoping to get another chance to share that experience with his loved ones.

"Obviously, you work hard to put yourself in a position to do that," he said. "So it would be amazing [to play in the All-Star Game]. 

"I love it. Not necessarily for me, obviously it is great, but I love it to be able to experience it with my family because they’re the ones that really make the true sacrifice, and have led me to dedicate myself to the game the way I’ve been able to do in the summers, and night-in, night-out.

"So I love to be able to let them enjoy it and see the rewards of it and stuff like that, that’s why it’s important. But for me, whatever the team needs night-in and night-out – whatever it is – I just want to help the team."

Erik ten Hag insists Manchester United will not be "burning money" on bringing in the wrong striker in January.

After a tough start to life as Red Devils manager, Ten Hag's team have been much improved of late and currently sit fourth in the Premier League after three straight league victories, despite being short of options up front.

Cristiano Ronaldo was in and out of the team before his bombshell interview with Piers Morgan led to his contract being mutually terminated, while Anthony Martial has struggled with injuries.

But despite the need for a centre-forward to help United's Champions League qualification bid, Ten Hag feels United must avoid the mistakes of the past by wasting finances on the wrong striker.

"You need one who can have an impact otherwise you are just burning money," Ten Hag told reporters. "You don't strengthen the squad and it doesn't help you.

"We have a good team when all are available. We have [a striker], Anthony Martial, I'm really happy with his performances across many games.

"He has had a really good impact. If you see his minutes and the impact he has had it's been huge."

One suggestion for United to boost their attacking ranks has been to recall Amad Diallo, who has scored six goals in 19 matches on loan at Championship side Sunderland.

But Ten Hag is reluctant to bring Diallo back to Old Trafford early, believing it would be wrong to stunt the progress the Ivory Coast international is making with the Black Cats.

"We consider everything. I have a little reservation because I don't want to stop the process, he is making good progress there," Ten Hag added. "Young players need experiences.

"When we decide [he needs] to come back he has to be a player who can compete for the starting 11 or at a minimum of coming on for a lot of games to have an impact."

Mikel Arteta will not stop anyone at Arsenal from dreaming about Premier League glory, but the Spaniard wants the Gunners to remain realistic ahead of Tuesday's huge meeting with Newcastle United.

Arsenal will move 10 points clear of Manchester City at the Premier League summit if they beat the Magpies at the Emirates Stadium, after the champions were held to a 1-1 draw by Everton on Saturday.

With the Gunners unbeaten in their past 10 league games (W9 D1), belief is beginning to build among supporters that a first title triumph since the 2003-04 season could be on the horizon.

Asked whether he needed to play down talk of the title, Arteta said: "It's not about stopping anybody. It's about being realistic about where we are. 

"The way we are performing, obviously it's impressive and we are really happy with that.

"But we also have to set the bars and objectives in the short term for what we want to improve and see what is making us win so many football matches."

Saturday's thrilling 4-2 victory at Brighton and Hove Albion was celebrated in joyous fashion by the Gunners' players, and Arteta has no qualms about the team enjoying their fine run of form. 

"It's great," Arteta said. "When I see those interactions, I see the enjoyment and I see joy and happiness because they were really excited after a big win for us.

"But they are also moderate and understanding as well. We still have a lot of things that we have to improve as a team."

While Arsenal are the only Premier League team with a 100 per cent winning record at home this season (7/7), Newcastle begin 2023 in third place after losing just once all campaign, and Arteta expects a tough test.

"They're a very good team, really well coached," Arteta said. "I think what that Eddie [Howe] has done in that short period of time, when you look at the numbers, is incredible. 

"Big credit to him and the coaching staff. They have created, I believe, a momentum around the team that they play the same way against any opponent.

"It's going to be another big test but we play at home in front of our crowd and we are looking forward to it."

Arsenal have won their past 11 home games against Newcastle in all competitions – only against Stoke City (an ongoing run since 1983) have they ever won more consecutive home matches (16).

The Los Angeles Clippers must wait on the status of franchise player Kawhi Leonard after he was a late addition to the injury report for Monday's home game against the Miami Heat.

Leonard, who has only played in 16 of the Clippers' 38 games this season, has been listed as questionable due to a non-COVID illness after suiting up for each of his side's past three outings.

After missing the entire 2021-22 season following an ACL tear in the 2021 playoffs, Leonard has slowly been recapturing the form that has earned him five NBA All-Star selections and seven NBA All-Defensive honours.

He averaged 10 points per game across his five games played in October and November, but looked back to his old self in December, posting 20.6 points, 7.0 rebounds and 4.2 assists in his 11 games played in the month.

Leonard also has fond memories of his time competing against the Heat, announcing his arrival as a star when he won the NBA Finals MVP in 2014, as the San Antonio Spurs defeated the LeBron James led 'Heatles' in their quest for a three-peat.

It is one of two Finals MVP trophies in Leonard's possession after also carrying the Toronto Raptors to an improbable championship in 2019, joining James and Kareem Abdul-Jabbar as the only players to win the award with two teams.

The Heat may also be undermanned for Monday's fixture, with Jimmy Butler, Caleb Martin, Gabe Vincent and Duncan Robinson all questionable due to various injuries.

Alexis Mac Allister is in no rush to make an exit from Brighton and Hove Albion after his World Cup triumph, despite reported interest from multiple European heavyweights.

The Argentina midfielder earned a recall to the national team at the start of last year and proved instrumental in helping Lionel Messi and company reach the summit at Qatar 2022.

His form had already been impressive for the Seagulls this term, but his performances with La Albiceleste have seen links to several major suitors only multiply since.

But speaking after his return to the Premier League outfit following an extended post-tournament break, Mac Allister has insisted he is happy at Brighton.

"I try not to read too much [into speculation]," he told the club's Albion TV channel. "I always say I am happy here. I don't have any rush to leave.

"I feel really good. I'm really grateful [for] this club, my team-mates and all the people who work here. I'm just focused on the next game."

Mac Allister's words will come as a boost to coach Roberto De Zebri, who warned on Monday the 24-year-old could find a mid-season switch an impediment to his game.

Chelsea, Arsenal, Liverpool and Juventus are among those all linked with a move for him, though the Blues' pursuit of Enzo Fernandez suggests they may have cooled their interest.

Mac Allister was one of eight Brighton players who headed to the World Cup, and the first Seagulls player to reach the tournament final in history.

The playmaker feels that the experience for all of the team's international stars however will benefit them going forward into 2023, as they look to press on for a top-six finish.

"It was a good World Cup for this club and for the players who went to the World Cup," he added.

"We know we’ve got a good team with really good players. This is a tough league, it will be hard, but we will try to finish as high as we can."

Jake DeBrusk did not want to see the Winter Classic end as he enjoyed a dream outing at Fenway Park, guiding the Boston Bruins past the Pittsburgh Penguins.

The Bruins replicated their 2010 feat – when they beat the Philadelphia Flyers 2-1 in the previous Winter Classic to be held at Fenway – by downing the Penguins by the same score on Monday.

DeBrusk was the hero with two third-period goals after Kasperi Kapanen gave the Penguins the lead in front of 39,243 fans in the NHL's annual outdoors game.

Speaking to TNT after the game – which the NHL-best Bruins have now won a record three times in four appearances – DeBrusk expressed his gratitude for the chance to play at Fenway.

"I've been lucky enough to play in three of these now, and just look around. I mean, this is Fenway Park all pretty much in yellow," DeBrusk said.

"It's one of those things where you almost don't want it to end."

DeBrusk expected team-mate Taylor Hall to make the decisive contribution after he tied things up by beating replacement goaltender Casey DeSmith just six seconds after a Pittsburgh penalty expired.

While DeBrusk ultimately proved the game-winner by knocking in a rebound with two minutes and 24 seconds left, the goal owed much to Hall's fine work.

"I actually thought it was going to be him [who scored]," DeBrusk said. "I was talking to him on the bench, saying, 'Hey Hallsy, it wouldn't be bad to score your first one at Fenway'."

The defeat leaves the Penguins in fifth in the Metropolitan Division with a 19-12-6 record for the season.

Head coach Mike Sullivan lamented fine margins, including an early injury to goaltender Tristan Jarry.

"There's a fine line between winning and losing", Sullivan said. "It comes down to subtle details. There were momentum swings on both sides in all periods.

"I don't have any update on Tristan. Obviously he is being evaluated for a lower body injury. It's tough to lose a guy that early in the game."

Martina Navratilova said she is "not done yet" after it was confirmed she had been diagnosed with throat and breast cancer.

Navratilova is one of the most decorated tennis players of all time, having won 18 grand slam singles titles between 1978 and 1990.

She successfully underwent treatment for breast cancer in 2010, but it has been revealed she is once again battling the illness.

A representative described Navratilova's prognosis as "good", and the 66-year-old said the disease was "serious but still fixable".

Navratilova has pledged to fight, posting on Twitter: "Needless to say my phone and Twitter are both blowing up.

"I will say again – thank you all for your support and I am not done yet."

The Czech also received support from Billie Jean King, who tweeted: "Martina is as brave as she is strong. She has fought this battle before, and she is in our thoughts and prayers."

Liverpool are "not a Jurgen Klopp team" at the moment, according to Jamie Carragher, who was scathing of the Reds' lacklustre performance in Monday's defeat at Brentford.

A deserved 3-1 victory for Thomas Frank's Bees further compounded the woes of the Merseyside outfit, who have struggled to recapture the highs of last season this term.

Since restarting their campaign after the World Cup concluded last month, Liverpool have been knocked out of the EFL Cup and staggered to muted Premier League wins against Aston Villa and Leicester City.

Defeat to an energetic Brentford side leaves them four points adrift of the Premier League's top four, and Carragher feels they no longer possess the characteristics associated with their decorated manager.

"That has been a theme of Liverpool all season," the former Reds defender told Sky Sports. "As soon as the intensity of a game rises, they cannot cope.

"They need to play a slower type of game because as soon as it goes fast, they are not at the races, they cannot keep up with it.

"When I watch Liverpool now, and certainly in midfield, it feels like Jurgen Klopp's team is morphing into something else.

"For me, from minute one of Klopp's era, teams were sprinting all over the pitch. When I don't see Liverpool sprinting and closing down now, it is not a Jurgen Klopp team and I want to know why."

Liverpool have already sought to bolster their ranks with the signing of Cody Gakpo, but Carragher claims offensive power is not their foremost issue, calling for the arrival of a midfielder.

"I don't know what has happened to Liverpool in terms of midfield," he added. "[They] have bought one midfield player in four-and-a-half years in Thiago [Alcantara]. It is coming back to haunt them now.

"They have signed Cody Gakpo [but] if Liverpool think they can make the top four without signing a midfield player in this window, they have got no chance."

Virgil van Dijk's half-time withdrawal in Liverpool's 3-1 defeat to Brentford was a precautionary measure after the defender struggled with the intensity of the game, Jurgen Klopp explained.

With an Ibrahima Konate own goal and a Yoane Wissa header putting Liverpool 2-0 down before the break, Klopp rang the changes by removing Van Dijk, Konstantinos Tsimikas and Harvey Elliott from the action.

While replacements Joel Matip, Andrew Robertson and Naby Keita initially had a positive impact, they were unable to stop the Reds from sliding to their first defeat against the Bees since 1938.

Van Dijk began the game as captain with both Jordan Henderson and James Milner out, and his withdrawal led to suggestions he had sustained an injury.

However, Klopp outlined his belief that the Netherlands skipper had avoided any lasting damage in his post-match press conference, revealing: "Virgil felt a little bit the muscle but said he is fine, and he's a very good judge of these kinds of things. 

"But I didn't want to take any risk – the physios looked quite happy when I said we don't take risks. I think it is not an injury, he just felt the intensity.

"The other two were tactical. We obviously had the opportunities.

"We could bring in Naby, who I think played a really good game, and Robbo – and Robbo with the first action after half-time was exactly what we needed. 

"We needed that speed in behind and so that was the reason for these two changes."

Liverpool's loss at the Brentford Community Stadium dealt a huge blow to their hopes of Champions League qualification, leaving them four points adrift of fourth-placed Manchester United having played a game more.
