Sergio Ramos has sustained another calf injury that casts early doubt on the Paris Saint-Germain centre-back being fit to face his former side Real Madrid in the Champions League.

The 35-year-old has been hampered by a series of niggling issues since arriving at PSG from Madrid, where he had spent the previous 16 seasons.

He played a part in PSG's last two matches, but a low-grade muscle problem suffered in training on Thursday could see the defender facing another spell on the sidelines.

PSG confirmed the news on their website on Sunday, with further tests planned for the middle of next week, and Mauricio Pochettino is unsure how long Ramos will miss.

"You never know with an injury. You have to follow the evolution. We don't know the duration of his unavailability," Pochettino said at a news conference.

Ligue 1 leaders PSG are set to host Madrid in the first leg of their Champions League last-16 tie on February 15, before travelling to the Spanish capital three weeks later.

Ramos has played just five times for Pochettino's side in all competitions since arriving in July, totalling 284 minutes of action on the field.

The 15 LaLiga games Ramos started in 2020-21 was the fewest he managed in a campaign for Madrid and a big drop from the 35 games started the season before.

Indeed, he played just eight matches in all competitions at club level in 2021, while his last appearance for Spain was against Kosovo last March.

PSG will also be without forward Neymar and midfielder Georginio Wijnaldum for Monday's Coupe de France last-16 tie with Nice.

Wijnaldum is expected to return from an ankle sprain at the end of next week, while Neymar – who has not played since November – will be further assessed on Monday.

However, Pochettino can still call upon superstars Kylian Mbappe and Lionel Messi for the cup match.

Messi has had a chance to work on his fitness this week, having not been included in Argentina's latest squad after recently being struck down by coronavirus.

And ahead of the Nice match, Pochettino has been encouraged by what he has seen from compatriot Messi.

"We are very happy with what Leo has done in training this week," Pochettino said. "He has trained well. He is in good condition to start.

"For Kylian, it's a question of complicity. Their connection is starting to see each other. They are two very great footballers.

"It's been a good week of work. I'm happy because we were able to work on the tactics, not just the physical side. We hope that this work will be seen by the end of the season."

Rick Carlisle was moved to tears by a video tribute on his first return to the Dallas Mavericks, who he then backed for a big season under successor Jason Kidd.

Carlisle was Mavs coach for 13 years before resigning at the end of last season, with Kidd appointed in his place.

Kidd was a player under Carlisle when they won the only NBA title in franchise history back in 2011.

Carlisle is now coach of the Indiana Pacers and, after winning his first matchup with the Mavs in Indiana in December, he returned to Dallas on Saturday.

As his achievements with the Mavs were recognised, Carlisle said: "I was not expecting anything like that. It was a wonderful gesture, very much appreciated."

Mavs superstar Luka Doncic added: "I've been with him my first three years and learned a lot of things.

"He helped me in a way, too, so it was a special moment. The tribute was special to him. You could see it, and he deserves it."

Kidd said: "He helped all of us achieve that one goal that we play for, and that was to win a championship. He set the bar high for the next coach or coaches."

Kidd is now giving it his best shot, as his team were far less accommodating of Carlisle on the court, dominating in a 132-105 victory – led by Doncic's 30 points and 12 assists.

The Mavs are on a 13-3 run, coinciding with Doncic's return to form and fitness, and have the talent to trouble the leading teams in the Western Conference – although Kristaps Porzingis exited with knee soreness against Indiana.

Carlisle, who recommended Kidd for his role, said: "He's done a tremendous job.

"His history here, as a player who was drafted here, a Hall of Fame player on a championship team here, I know the kind of warrior he is when it comes to winning and how smart he is. They're a major threat in the West."

Manchester United are waiting to establish the facts before commenting further on allegations made against Mason Greenwood on social media.

The club said on Sunday they were "aware of images and allegations circulating" in relation to the England forward.

A statement released to Stats Perform read: "We are aware of images and allegations circulating on social media.

"We will not make any further comment until the facts have been established. Manchester United does not condone violence of any kind."

Julian Alvarez is poised to sign for Manchester City, River Plate have confirmed, but the forward will return to Argentina on a loan that could yet be extended into next season.

Forward Alvarez enjoyed an outstanding 2021, scoring 24 goals in 46 games in all competitions for River.

That form saw the 21-year-old break into the Argentina senior squad and has also now earned him a big move to Premier League champions City.

A deal reportedly worth £15.4million (€18.5m) is set to be completed before Monday's transfer deadline in England, but Alvarez will then head back to River at least until July.

And River president Jorge Brito hopes a run in the Copa Libertadores could see City agree for their newest recruit to continue his loan into the second half of 2022.

"Julian is almost an addition for us," Brito told ESPN. "He is almost irreplaceable for [coach Marcelo] Gallardo.

"The loan is until July 7 – although there is a clause that speaks of the 'greatest efforts' between the three parties: we, who are the sellers, Manchester City, which is the buying club, and the player.

"There are possibilities that he will continue with us if River continues in the Copa next season."

Golden State Warriors head coach Steve Kerr is not worried about Stephen Curry's recent shooting slump after another "tough night" in Saturday's 110-106 win over the Brooklyn Nets.

Curry made 14 of his 19 points in the final quarter, shooting five-of-18 for the game including three-of-10 from beyond the arc, as the Warriors edged past the Nets minus James Harden (hand) and Kevin Durant (knee).

The two-time MVP's struggles continued a below-par recent run, shooting at 35 percent from the field and 29 percent from beyond the arc in his past five games. Curry has shot at 42 percent from the field and 38 percent from three-point range across this season.

"It's a question I'll keep getting if he's not shooting the ball well, but I'm not worried about him," Kerr said at the post-game news conference.

"I'm not. He's Steph Curry, one of the great players of all time. He's had a tough night tonight but he helps us win routinely and does so much beyond just making shots. It'll come round for him."

Curry has previously been impacted by a hand injury and appeared to favour that at times on Saturday but Kerr insisted it was not currently an issue or reason for his slump.

"He's told me he feels great physically," Kerr said. "We've talked a lot about the schedule and the minutes.

"I'm really aware of what needs to happen in terms of monitoring his minute and when we can push him harder and when we can't. I think he's in a good place physically. He's going to be fine."

Curry became the Warriors' all-time career leader in games after surpassing Chris Mullin's mark of 808 appearances on Saturday.

The 33-year-old point guard broke the NBA's all-time record for most three-pointers made earlier this season while he also holds several single-season team milestones too, but Kerr praised Curry's loyalty, having been with the Warriors since being pick seven in the 2009 NBA Draft.

“I love that particular record just because it signifies his loyalty to the franchise and vice-versa,” Kerr said pre-game.

“The love affair that exists between Steph and The Bay is pretty unique.”

First-time All-Star Andrew Wiggins kept the Warriors going in the first half with 17 points, finishing with a team-high 24 points along with eight rebounds, three steals and two blocks.

"Andrew was phenomenal tonight. [Two] blocks and three steals," Kerr said. "[He was] All over the place defensively and on offense he was our most consistent player.

"He carried us in the first half. He’s playing with a lot of confidence and showing why he's an All-Star."

Meanwhile, Nets head coach Steve Nash offered an update on Harden who missed the game with a hand strain.

"We'll have to see how it settles but we're hopeful [for next game]," Nash said.

Stephen Curry and Klay Thompson came to life in the final quarter as the Golden State Warriors edged the short-handed Brooklyn Nets 110-106 on Saturday.

Curry struggled with his shooting throughout, going five-of-18 from the field, but found his range late, scoring 14 of his 19 points in the final quarter to lead Golden State to victory despite Kyrie Irving's game-high 32 points for the Nets, who were without James Harden with a hand strain.

Thompson also had his issues shooting five-of-14 for the game, but scored nine fourth-quarter points including a clutch three-pointer to make it 107-103 with 12.1 seconds left.

Five-time All Star Thompson finished with 16 points, while Curry had 19 points, with seven rebounds and eight assists. First-time All-Star Andrew Wiggins led the Warriors' scoring with 24 points, including 17 in the first half.

Irving had seven rebounds and seven assists to go with his 32 points which included three triples, while Patty Mills hit six three-pointers in his 24 points.

The Warriors, who are 24-4 at home this season, improve to 37-13, while the Nets move to 29-20.

Embiid and Morant continue hot streaks

Joel Embiid led the Philadelphia 76ers' rally from a 17-point deficit as they won 103-101 over the Sacramento Kings. Embiid scored 25 or more points for the 17th consecutive game, finishing with 33 points, 12 rebounds and six assists, while Tyrese Haliburton had 38 points for the Kings.

First-time All-Star Ja Morant scored 34 points including four three-pointers as the Memphis Grizzlies defeated the Washington Wizards 115-95, while Jayson Tatum starred with 38 points, eight rebounds and seven assists in the Boston Celtics' 107-97 victory over the New Orleans Pelicans.

Jimmy Butler had a triple-double with 37 points, 14 rebounds and 10 assists but the Miami Heat went down in triple overtime 124-120 to the Toronto Raptors. Gary Trent Jr had 33 points for Toronto who had blown a 10-point three-quarter time lead.

Pacers battle as Doncic stars for Mavs

The Indiana Pacers' road struggles continued with their 20th loss in 26 games away from home, with Luka Doncic dominant as the Dallas Mavericks blew them out 132-105 with 30 points, six rebounds and 12 assists. 

James Harden was absent from the Brooklyn Nets starting line-up on Saturday for the second straight game but this time it was due to a separate issue.

Harden missed Saturday's game against the Golden State Warriors with a right hand issue which required an MRI that showed a strain.

The 2018 MVP had missed Wednesday's 124-118 loss to the Denver Nuggets with left hamstring tightness.

"James' hand has been bothering him for a few days," Nets head coach Steve Nash told reporters before the Warriors game.

"He thought it was nothing and then it really flared up this morning when he woke up. Obviously he irritated what he was feeling [Friday] and then this morning he woke up with some irritation so we had a scan.

"I think what we're calling it is a hand strain from the doctor. Just unfortunate."

Harden had got through Friday practice with the Nets, already without Kevin Durant due to a left knee sprain, who had expected him to play on Saturday.

Nash did not provide a timeline on 32-year-old Harden's return to play but indicated it was minor.

"Clean of the bad stuff, but a strain for sure," Nash said of the MRI. "There's stuff on the MRI, so he's feeling something, feeling the strain.

"It's been bothering him, but he was like, 'Yeah, it's nothing'. Now it's a little more than nothing. He woke up with a marked difference in the hand."

Luke List has had a long wait for his first PGA Tour win and that was extended after a two-hour wait before triumphing in a playoff over Will Zalatoris at the Farmers Insurance Open on Saturday.

The 37-year-old American, enjoyed an excellent final round six-under-66, highlighted by four consecutive birdies from the third to the sixth holes, to storm up the leaderboard at Torrey Pines.

But List, in his 206th career start, waited almost two hours after entering the clubhouse as the overnight leaders completed their rounds before facing Zalatoris, who also finished 15-under overall, in an 18th hole playoff.

In fading light, the pair both landed their tee shots within inches of each other in a bunker, with List's third shot placed close to the hole, enabling him to tap in to card a birdie.

Zalatoris pushed his longer birdie putt, which was near-identical to his 18th hole putt for victory that he missed, wide left again to settle the playoff in List's favour.

California-born 25-year-old Zalatoris may have clinched victory on the 18th as List patiently waited and practiced elsewhere, but was agonizingly short and slightly wide after a late fade on his putt.

He carded a final round one-under-71, grouped alongside Jason Day and Aaron Rai, with world number one Jon Rahm also making a late charge.

Day shot into a share of the lead after landing an eagle on the 14th hole but had to settle for joint third alongside Rahm and Cameron Tringale at 14-under-par overall.

The Australian, who had not won a PGA Tour title in 1,364 days, finished with back-to-back bogeys to slip from contention.

Rahm rolled in a clutch 26-foot putt to birdie the 17th to be one shot off the pace but only managed par on the last hole.

Joaquin Niemann, Justin Rose, Pat Perez, Sungjae Im and Rai were next, finishing 13-under overall.

The Cincinnati Bengals will hope the NFL has no reason to fine Tyreek Hill for celebrating once Sunday's AFC Championship Game with the Kansas City Chiefs is in the books.

Hill was not flagged for flashing the peace sign at a collection of Buffalo Bills defenders as he left them for dead while scoring a 64-yard touchdown in the Chiefs' remarkable 42-36 victory in the Divisional Round last Sunday.

That score marked one of the five lead changes after the two-minute warning in a contest viewed as one of the greatest in the history of the NFL playoffs.

While the officials on the field at the time did not see fit to penalise Hill for taunting, it was revealed on Saturday he was fined over $10,000 by the league for his actions in the act of scoring.

Hill and the Chiefs are heavy favourites to see off the Bengals and progress to a third successive Super Bowl.

However, after holding the Tennessee Titans to 16 points in their Divisional Round triumph, Cincinnati will look to keep Hill in check.

The Bengals did just that in their Week 17 win over the Chiefs, holding him to six catches for 40 yards.

And Cincinnati safety Vonn Bell made it clear earlier this week that the Bengals are ready for the test posed by Kansas City's speed on offense.

"They've got speed. They've got [Mecole] Hardman and they've got [Byron] Pringle, they've got [Hill]," Bell said. "It brings a lot of problems because it stretches you vertically. [Because] you want to take away these vertical threats and everything underneath.

"You've got [Jerick] McKinnon, you got [Clyde Edwards-Helaire] back, you got Travis [Kelce] sitting underneath in the soft of the zone. It was just like, 'Man, everybody's back deep and he's just by himself.' You've got to respect the speed, because it's like a roadrunner, we call them, and they just keep on rolling.

"That's why this team is so dynamic. You got guys like Hardman and [Hill] that can line up anywhere, backfield, anywhere they could do punt returns and they can create explosives everywhere. It's a unique group that they have, and it's a challenge for sure. We rise up to it and we're ready to take it on for sure."

A Fulham supporter has died after suffering cardiac arrest in the stands at Craven Cottage during Saturday's Championship game against Blackpool. 

The fan, named by the club as Paul Parish, received treatment from the medical staff of both clubs, while supporters provided privacy with flags. 

The match was suspended, and the players returned to the dressing rooms, later resuming to play out a 1-1 draw.

A statement on Fulham's official Twitter account published later on Saturday read: "It is with immense sadness that we inform fans of the passing of supporter, Paul Parish.

"Paul suffered a cardiac arrest and received treatment in the stand at this afternoon's match before being transferred to hospital.

"Our condolences go out to Paul's loved ones."

Tom Brady is reportedly retiring from the NFL, and one of his favourite targets led the tributes on social media.

Reports of the end of Brady's 22-season career, one which delivered an unprecedented seven Super Bowl titles, emerged on Saturday.

Brady's agent, Don Yee, has since moved to clarify that a final decision has yet to be made on his client's future.

By that point, though, stars from around the sporting world had taken to Twitter to express their admiration for the man regarded as the NFL's greatest of all time.

Edelman, with whom Brady won three Super Bowls with the New England Patriots, was among the first to do so.

He was joined by Kansas City Chiefs quarterback Patrick Mahomes, whom Brady beat in the AFC Championship Game en route to winning his final Super Bowl with the Patriots in the 2018 season and again in last year's Super Bowl with the Tampa Bay Buccaneers.

Bucs team-mates Chris Godwin, Mike Evans and Richard Sherman spoke of their pride at having shared the field with Brady, while 2012 MVP Adrian Peterson also congratulated the quarterback on the most remarkable of careers.

James Harden, Donovan Mitchell, Kevin Love and Bradley Beal were among those from the NBA to pay tribute to the GOAT.

Tom Brady will soon clarify whether he plans to retire from the NFL or not, according to the Tampa Bay Buccaneers star's agent.

It was reported by ESPN on Saturday that the record seven-time Super Bowl champion would bow out of the game after 22 seasons.

Rumours emerged prior to the Bucs' Divisional Round playoff loss to the Los Angeles Rams that the 44-year-old was non-committal about playing beyond the 2021 season.

The New England Patriots great previously expressed a desire to play to age 45 and was open to the idea of continuing until he turned 50.

But speaking on the 'Let's Go' podcast this week, Brady said of his wife and family: "It pains her to see me get hit out there. And she deserves what she needs from me as a husband and my kids deserve what they need from me as a dad.

"Playing football, I get so much joy from [it]. I love it. But not playing football, there's a lot of joy in that for me also now, too, with my kids getting older and seeing them develop and grow. So, all these things need to be considered and they will be."

After news of his apparent decision to call time on his career as the greatest quarterback in history, Brady's agent, Don Yee, asked for patience.

In a statement carried by ESPN, he said: "I understand the advance speculation about Tom's future. Without getting into the accuracy or inaccuracy of what's being reported, Tom will be the only person to express his plans with complete accuracy.

"He knows the realities of the football business and planning calendar as well as anybody, so that should be soon."

Dango Ouattara scored and was later sent off as Burkina Faso advanced to the Africa Cup of Nations semi-finals with a 1-0 win over Tunisia. 

Ouattara's first international goal means Kamou Malo's men will now face Senegal or Equatorial Guinea, who meet on Sunday, in Wednesday's last-four tie, although the Lorient forward will be absent after receiving a red card for a heavy aerial challenge. 

Wahbi Khazri went close with a free-kick as Tunisia dominated much of the first half, yet it was Burkina Faso who went in at the interval ahead.

Ouattara latched onto Ibrahim Toure's pass, checked back inside two Tunisia defenders and fired a left-footed strike past Bechir Ben Said three minutes into stoppage time. 

Tunisia thought they would be given the chance to restore parity late on when referee Joshua Bondo was encouraged to check the pitchside monitor by VAR following Soumaila Ouattara's challenge on Khazri in the penalty area, but the official stuck with his initial decision. 

He agreed with VAR soon after, though, dishing out a red card to Ouattara after he had caught Ali Maaloul in the face with an elbow. Despite their numerical disadvantage in the closing eight minutes, a resolute Burkina Faso held on to book their spot in the last four.
