The San Francisco 49ers are looking to end the regular season in style as they welcome back All-Pro receiver Deebo Samuel and former starting running back Elijah Mitchell from injuries.

Arguably the hottest team in the NFL currently, the 49ers are currently riding a nine-game winning streak, and have done so in spite of some serious injuries.

Their past five wins have come with seventh-round rookie Brock Purdy playing quarterback after starter Jimmy Garoppolo suffered a season-ending injury, while Mitchell has also missed the past five games and Samuel was carted off in Week 14.

Sitting at 12-4 after beginning the campaign 3-4, the 49ers have already punched their ticket to the playoffs, but remain a chance to earn the NFC's top seed along with the Philadelphia Eagles (13-3), Minnesota Vikings (12-4) and the Dallas Cowboys (12-4).

They will enter their season finale against the visiting Arizona Cardinals as heavy favourites, with the road team on a six-game losing streak and without starting quarterback Kyler Murray since tearing his ACL.

The Los Angeles Clippers have opted to rest All-NBA duo Kawhi Leonard and Paul George on the second leg of their back-to-back against the Minnesota Timberwolves on Friday.

It is a curious decision after neither player eclipsed 18 minutes in Thursday's 122-91 blowout loss against the Denver Nuggets, where they both sat out the entire second half.

Leonard has officially been listed out due to "injury management", while George may have picked up a niggling injury as he is listed out due to his hamstring.

Their absence leaves the Clippers in a difficult situation as they head to Minnesota undermanned and on a four-game losing streak, although they remain in the thick of the playoff picture at 21-19 – currently sixth in the Western Conference.

Leonard has only played in 17 of the Clippers' 40 games so far, but after easing his way back into things in October and November, he began to look like himself in December.

In his 11 games this past month, Leonard averaged 20.6 points, 7.0 rebounds and 4.2 assists per contest while shooting 49.1 per cent from the field.

Meanwhile, George has made 30 appearances this campaign, averaging 23.7 points, 6.0 rebounds and 5.1 assists, and remains on track for what would be his eighth All-Star selection.

The Cleveland Browns' franchise player Myles Garrett declared his side is looking for "volunteers, not hostages" after fellow pass-rusher Jadeveon Clowney took to the media to complain about his role this week.

In an interview with Cleveland.com on Thursday, Clowney stated he felt the Browns are more concerned about getting Garrett "into the Hall of Fame instead of winning games".

He referenced the roles each of the two former number one overall draft picks were being asked to play, implying Garrett is being placed into the more favourable matchups in order to boost his statistics.

Since entering the league in 2017, Garrett has been one of the top talents at one of the sport's most valuable positions.

He finished with seven sacks as a rookie before rattling off season totals of 13.5, 10, 12, 16 and another 15 this year to bring his career tally to 73.5 – already surpassing the Browns' franchise record (62) at the age of 27.

He is fourth in the league in sacks this season, while Clowney, who has never reached double-digit sacks in any of his nine seasons, has just two in 12 games this campaign.

Speaking to reporters on Friday about Clowney's comments, Garrett said he was disappointed.

"I knew he was frustrated," he said. "We've all been frustrated – we're not winning.

"I wish we could've talked about this man-to-man... I wish he would have handled it a little bit differently."

He also broke down why he believes Clowney's narrative is false, pointing out he receives the most double-team blocks (31.3 per cent of the time) in the entire league.

"If I'm the most double-teamed guy, it's hard to say I'm getting the most favourable matchups," he said. "What I've done speaks for itself. 

"Of course they're going to put me in positions to make plays. But they're also going to be positions where I'm going to get double-teamed. 

"I move all over the line. [Clowney] has moved, as well. We're both moved to be put in favourable matchups. He's getting those same looks, at least that's what I see, and I wish we could have talked about it."

Garrett said the Browns are looking for "volunteers, not hostages" when asked if he would welcome Clowney back for a third consecutive season.

"If you feel like no one believes in you here, then go where you feel like you're wanted and loved and appreciated," he said.

Clowney, who turns 30 in February, will be a free agent this offseason.

The NFL's one-season rule change could have complicating factors for the Kansas City Chiefs further down the line, but their task for Week 18 is simple: beat the Las Vegas Raiders and earn a bye to the divisional round.

With the Buffalo Bills and the Cincinnati Bengals – both rivals for the first seed in the AFC – to finish the year having played only 16 games, neither will be able to catch the Chiefs should they defeat the Raiders.

That will not necessarily mean an AFC Championship Game at Arrowhead Stadium, with a neutral venue potentially coming into play, but it does assure them of a week off and a favourable route through the postseason.

Fans in Buffalo and Cincinnati could reasonably be frustrated, and their hopes of the Chiefs being halted rest with an unlikely Raiders victory.

The Chiefs are 9-1 in their past 10 games against the Raiders, and their most recent nine meetings – including a high-scoring defeat in 2020 – have seen Kansas City score at least 28 points.

Only the Los Angeles Rams against the Green Bay Packers, between 1949 and 1953, have ever scored 28 or more points in 10 straight encounters.

Even in Las Vegas, there is little reason to believe that sequence will end this week, given the Chiefs' dominant road form this year.

They have scored 264 points across eight games away from Arrowhead, meaning the Chiefs will have scored the third-most road points in a season in NFL history if they hit their average of 33.0 again.

MVP frontrunner Patrick Mahomes loves playing the Raiders, too, having thrown more touchdowns in this matchup (26) than in any other.

In 2022, he has passed 5,000 passing yards (5,048) and 250 rushing yards (329) in a season for the second time in his career; only two other quarterbacks in NFL history have ever enjoyed one such campaign (Jameis Winston in 2019 and Justin Herbert in 2021).

Yet the Raiders improbably have their own in-form QB, with former New England Patriots backup Jarrett Stidham last week impressing in his first career start.

Stidham threw for 365 yards and three TDs against the San Francisco 49ers, joining Mike White last season as the second QB in the Super Bowl era to mark his first start with 350 passing yards and three passing TDs.

Repeating that performance against the highly motivated Chiefs is a tough ask, though.

Paris Saint-Germain left out their biggest stars and survived a scare to progress in the Coupe de France, earning a 3-1 win at Chateauroux on Friday.

An early goal from Hugo Ekitike was cancelled out by Natanael Ntolla before half-time, and PSG had to wait until the 78th minute for Carlos Soler to bundle home for the Ligue 1 side before Juan Bernat added some gloss to the score late on.

Christophe Galtier included 16-year-old Warren Zaire Emery in his much-changed starting line-up, with no Lionel Messi, Neymar or Kylian Mbappe as Ekitike, Pablo Sarabia and Soler were selected in attack.

Chateauroux, who play in the third tier of French football, belied their lowly position of 14th in the Championnat National with a determined showing against their celebrated opponents, but PSG ultimately made it through to the last-32 stage.

The visitors took the lead in the 13th minute when Ismael Gharbi's first-time ball from the edge of the box into the path of Ekitike allowed the young striker to finish neatly in off the left post with the outside of his right foot.

Jonathan Mexique went close for the home side with a close-range shot in the 26th minute that was deflected over by a diving Vitinha, while Paul Delecroix made a good save down to his left from a Gharbi volley shortly after.

The scores were level eight minutes before the break though after neat work down the left ended with former Lille and Saint-Etienne striker Nolan Roux pulling the ball back for Ntolla, whose goal-bound shot was deflected past Keylor Navas by 17-year-old PSG defender El Chadaille Bitshiabu.

Galtier called for more experience in the second half as Sergio Ramos and Fabian Ruiz came on just after the hour, and the coach eventually saw his team re-take the lead as Vitinha stood up a cross to the far post that allowed Ekitike to head at goal, with Soler following up from Delecroix's initial save.

Bernat made it 3-1 in stoppage time after racing onto a ball from Ruiz and firing low and hard across Delecroix to seal the victory for PSG.

Marcus Rashford was involved in all three goals as Manchester United secured a place in the FA Cup fourth round with a 3-1 victory over Everton at Old Trafford on Friday.

Frank Lampard's side had experienced a run of five defeats in six in all competitions, and they were soon behind when Rashford excellently set up Antony to put United 1-0 up.

Although Everton levelled when Conor Coady took advantage of a David de Gea howler to stab in, more silky work from Rashford restored United's lead as Coady turned his cross past Jordan Pickford for an own goal.

In-form United needed a reprieve in the shape of a VAR review to deny Dominic Calvert-Lewin a second equaliser, but Rashford got a goal for himself with a stoppage-time penalty as the Red Devils deservedly advanced to maintain their interest in silverware on four fronts.

United were ahead after just four minutes, with Rashford driving past his man before finding a pinpoint cross for Antony to poke home, and it could have been 2-0 moments later when Anthony Martial sent a dipping effort just past the post.

But Everton nearly levelled when Demarai Gray's long-range drive crashed off the woodwork, and they did soon find an equaliser as De Gea somehow let the ball through his legs from Neal Maupay's cross before Coady tapped in.

Rashford played a big role again for United's second, however, brilliantly powering to the byline before his low delivery was turned into his own net by Coady.

The introduction of Everton striker Calvert-Lewin almost reaped dividends when he got on the end of Gray's cross to seemingly level, only for the VAR to spot the winger's offside in the build-up.

There was time then for Ben Godfrey to tangle with Alejandro Garnacho and give Rashford an opportunity from 12 yards, which he confidently took to cap a brilliant display and make sure of United's place in the draw.

Skylar Thompson will start for the Miami Dolphins in a must-win Week 18 game against the New York Jets that could be decided by his ability to produce explosive plays.

The Dolphins are on a five-game losing streak that has dropped them from 8-3 to 8-8 and on the outside of the playoff picture looking in.

Yet Miami will qualify for the postseason if the Dolphins beat the Jets – who were eliminated with last week's loss to the Seattle Seahawks – and the New England Patriots lose to the Buffalo Bills.

The task of achieving that feat has been complicated by the Dolphins' quarterback situation.

Tua Tagovailoa remains out of action having been placed in the concussion protocol following the Dolphins' Christmas Day loss to the Green Bay Packers, and his backup Teddy Bridgewater suffered a finger injury in the defeat to the Patriots last week.

Thompson was subsequently thrown into the fire and never came close to rallying the Dolphins to a key victory, having also looked ill-equipped to lead the attack in a 40-17 loss to the Jets in Week 5, in which Bridgewater was injured on the first offensive play for Miami while filling in for Tagovailoa after he was concussed against the Cincinnati Bengals.

But the Dolphins have no choice but to look to him to thrive throwing the ball for a passing attack that has racked up 60 passing plays of 20 yards or more, a tally that trails only the Philadelphia Eagles (61) and Kansas City Chiefs (71).

The problem is that the Dolphins are facing a defense that has excelled at taking away the big play.

Indeed, the only team to allow fewer 20-yard pass plays than the Jets (36) are the New Orleans Saints (33).

With the Jets coaching staff perhaps coaching for their jobs, Dolphins head coach Mike McDaniel will expect his opponents, led by his former San Francisco 49ers colleague Robert Saleh, to offer another stern test.

If Thompson and the Dolphins cannot find a way to come through it and miss out on the playoffs, there will be plenty of questions about what went wrong in a season that once looked so promising.

David Beckham's playing career may be over, but one Premier League club will list a Beckham among their ranks this season after the former England captain's son Romeo joined Brentford.

The young Beckham made 20 appearances for Inter Miami II – the reserve side of his father's Major League Soccer franchise – in the MLS Next Pro league last season.

The 20-year-old previously spent time in Arsenal's academy before being released in 2015, and he joined Inter Miami II in 2021 when the team were known as Fort Lauderdale CF.

In a statement released on Friday, Brentford revealed the winger would join their B team until the end of the season.

"Brentford are delighted to announce the signing of Romeo Beckham from Inter Miami CF on loan until the end of the 2022-23 season," the club said.

"The 20-year-old will join Neil MacFarlane's B team for the rest of the campaign to continue his development as he makes the temporary switch from the MLS club. The move is subject to international clearance."

Revealing Beckham had been training with the club since the end of the MLS Next Pro season, MacFarlane said: "He came to us from Inter Miami with the aim of working with us during their close season.

"Romeo has applied himself unbelievably well, he's really bought into the culture and the group which he has become a big part of. I love his standards and the way he conducts himself on and off the pitch."

The new recruit said he was relishing his opportunity, telling Brentford's website: "I'm very proud and very happy to be here.

"I came here at the start to keep fit during the off season. The chance then came to come on loan here and I've never been so excited."

Last July, Inter Miami coach Phil Neville defended his decision to bring on Beckham – as well as his own son Harvey – in a friendly against Barcelona, saying they both "earned the right" to feature in a game which ended in a 6-0 defeat for the MLS side.

Antonio Conte has joined those paying tribute to Gianluca Vialli with a heartfelt social media post, describing his former Juventus team-mate as a "lion" and "an inspiration".

Vialli's passing at the age of 58 was confirmed on Friday, with the former striker having been re-diagnosed with pancreatic cancer in 2021 after being given the all-clear the previous year.

Conte played with Vialli throughout the latter's four-year spell with Juventus between 1992 and 1996, helping the Bianconeri win the Champions League in Vialli's final season with the club, during which he was club captain.

Conte took to Instagram on Friday to share a recent image of the pair dining together, alongside the caption: "Having dinner together in London a few months ago as we had fun remembering all our adventures and battles on the field.

"Unfortunately, in these last few years you had to fight a great and terrible battle in life.

"I told you and wrote that you have always been an inspiration to me as my captain and for how you were proving to be strong, proud and brave, fighting like a lion against this disease.

"Always in my heart my friend. Goodbye Gianluca."

Vialli spent much of his playing career at Sampdoria before joining Juventus in 1992, winning one Scudetto, one Coppa Italia and the UEFA Cup in addition to the Bianconeri's 1996 continental triumph.

He then left the club for Chelsea, where he eventually took over as manager, with Conte succeeding him as Juventus captain upon his departure.

NFL owners voted on Friday to approve a possible change to this year’s playoff format, allowing for a neutral-site AFC championship game if the participants were affected by Monday's cancelled game betweeen the Buffalo Bills and Cincinnati Bengals.

The ruling comes a day after the proposed changes were approved by the league's competition committee.

Monday's game between the Bills and Bengals was suspended after Bills safety Damar Hamlin went into cardiac arrest on the field and needed to be resuscitated, shocking the sporting world and leaving the NFL with questions about how to proceed.

On Thursday, the NFL said it would not finish the game and officially ruled it as a no contest, leaving the Bills and Bengals – both AFC contenders – with one fewer game played than the rest of the league.

If Cincinnati or Buffalo qualify for the AFC Championship game as the road team and could have been the home team with one more win, this new provision would move the game to a neutral site.

The rule also allows for a coin flip to decide the host of a potential Wild Card round game between the Bengals (11-4) and Baltimore Ravens (10-6) if the Ravens win the matchup between the teams in the regular-season finale on Sunday.

The new procedures are not without controversy and have already received some criticism from fans of the Kansas City Chiefs (13-3), who can secure the AFC's top seed and first-round bye with a Week 18 win over the Las Vegas Raiders. There are scenarios, however, in which the Chiefs would lose the right to host an AFC title game at Arrowhead Stadium against the Bills (12-3).

The league's policy manual says that "a team's standing in its division or in its conference” is to be decided by winning percentage in the case of a disparity in games played, but the league deemed Monday's cancellation extraordinary enough to warrant a new ruling.

It is the first time since 1935 that NFL teams will have played different numbers of games in a season, leaving no modern precedent on which the league could lean.

While the NFL has been tweaking its playoff format, Hamlin has gradually made progress during his four days at the University of Cincinnati Medical Center.

Hamlin, whose heart was re-started twice Monday, is now able to breathe on his own and had his breathing tube removed overnight. The 24-year-old even joined his team-mates briefly on a video call Friday with a simple message: “Love you boys.”

In a Friday statement, the Bills said Hamlin's "neurologic function remains intact and he has been able to talk to his family and care team."

Cincinnati Bengals head coach Zac Taylor is unhappy with the NFL's alterations to the playoffs, which could cost his team home-field advantage.

On Friday, NFL owners voted to approve proposed changes after the Bengals' game against the Buffalo Bills on Monday, in which Damar Hamlin suffered a cardiac arrest, was cancelled.

Those changes would include a coin toss to decide who would host a Wild Card round clash between the Bengals and the Baltimore Ravens if Cincinnati lost to their AFC North rivals in their final regular season game this week.

Meanwhile, a neutral venue will be used for the AFC Championship Game if it is contested between two teams who have played different numbers of regular season games and the lower-seeded team could have been the number one seed by playing a full 17-game season.

Taylor, who preferred the Bengals to be judged simply by their winning percentage, believes the outcome is unfair as Cincy are dealt "only negatives" by the decision.

"What's in front of us is to win this weekend and reclaim the opportunity to have a home-field Wild Card game. That's the task that's at hand in front of the team," the Bengals coach told reporters on Friday.

"As far as I'm concerned, we just want the rules to be followed and when a game is cancelled that you just turn to winning percentage to clarify everything, so we don't have to just make up the rules.

"There's several instances this season where the club is fined or people in our building are fined and we are being told to follow the rules. It's black and white in the rulebook.

"Now, when we point out the rules, you are told we are going to change that. I don't want to hear about fair and equitable when that is the case.

"What this team will do is all we can control, going into a game this weekend and doing our best to win. We are going to channel our energy into that.

"Opportunities are lost for us that we had a chance to control; now we don't. It seems like there are positives for a lot of teams and just negatives for us.

"We have the opportunity to play for a coin flip that can only negatively impact us; we don't have the opportunity to play for a coin flip that positively impacts us.

"Let's just follow the rules; we accept that. We just have to turn our focus to getting ready for Baltimore and doing everything we can to control what we can control at that point."

Southampton have signed Croatia winger Mislav Orsic from Dinamo Zagreb in an attempt to boost their Premier League survival hopes.

Orsic – who made six appearances for Croatia at the World Cup in Qatar and scored a sublime winner in their third-place play-off success against Morocco – has signed a two-and-a-half-year deal at St Mary's.

Southampton reportedly convinced Dinamo to part ways with Orsic by making a bid of £6million plus add-ons after Everton and Nottingham Forest were also linked with the 30-year-old.

Saints sit bottom of the Premier League table and three points adrift of safety after Wednesday's 1-0 defeat to Forest, their sixth consecutive loss in the competition.

Southampton manager Nathan Jones was only appointed as Ralph Hasenhuttl's successor in November, but he is already under pressure after becoming the second Saints boss to lose each of his first four Premier League games after Nigel Adkins in the 2012-13 season.

Jones will hope Orsic can transfer his outstanding record against English teams in continental competitions into the Premier League.

Orsic scored the only goal of the game as Dinamo beat Chelsea in their Champions League opener earlier this season, while he also netted a stunning hat-trick in a Europa League win against Tottenham in 2021.
