Johnny Sexton will miss Ireland's Six Nations clash with France on Saturday due to a hamstring problem.

Ireland captain Sexton surpassed 500 points in the competition last week, as he helped Andy Farrell's team to a 29-7 defeat of reigning champions Wales in Dublin.

However, the 36-year-old will not feature in Paris after sustaining an injury in training on Wednesday, and James Ryan will captain Ireland instead.

Joey Carbery will replace Sexton in Farrell's line-up, which was announced on Thursday. It is the only change Ireland have made.

Iain Henderson, Robbie Henshaw and Jack Carty have come into the squad and will be on the bench, with Ryan Baird and James Hume dropping out.

France, meanwhile, have made two alterations to their side, with Francois Cros and Yoram Moefana replacing Dylan Cretin and Jonathan Danty respectively.

Antoine Dupont was one of 11 players to assist a try across the opening weekend and now has 12 assists to his name in the Six Nations, the most of any France player.

The scrum-half will again look to dictate the play as Les Bleus aim to win their opening two games in an edition of the Six Nations for the third year in a row, this after managing it just twice in their previous eight campaigns in the Championship.

This will be the 101st meeting between the nations, with France winning 58 times and Ireland triumphing on 35 occasions.

Les Bleus have the edge in the Six Nations, winning half of their 22 encounters, including the two most recent games.

They thrashed Italy 37-10 in their opening fixture to go top of the standings after round one.

Ireland team:  Hugo Keenan, Andrew Conway, Garry Ringrose, Bundee Aki, Mack Hansen, Joey Carbery, Jamison Gibson-Park; Andrew Porter, Ronan Kelleher, Tadhg Furlong, Tadhg Beirne, James Ryan, Caelan Doris, Josh van der Flier, Jack Conan.

Replacements:  Dan Sheehan, Cian Healy, Finlay Bealham, Iain Henderson, Peter O'Mahony, Conor Murray, Jack Carty, Robbie Henshaw.

France team:  Melvyn Jaminet, Damian Penaud, Gael Fickou, Yoram Moefana, Gabin Villiere, Romain Ntamack, Antoine Dupont; Gregory Alldritt, Anthony Jelonch, Francois Cros, Paul Willemse, Cameron Woki, Uini Atonio, Julien Marchand, Cyril Baille.

Replacements:  Peato Mauvaka, Jean-Baptiste Gros, Demba Bamba, Romain Taofifenua, Thibaud Flament, Dylan Cretin, Maxime Lucu, Thomas Ramos.

France head coach Didier Deschamps labelled Kurt Zouma's behaviour "shocking" and "intolerable" after a video emerged of the West Ham defender abusing his cat.

The 27-year-old's actions were condemned by his club – who fined him a reported £250,000 and donated it to charity – along with the RSPCA, who took Zouma's cats into care, and several other animal welfare organisations.

Adidas also cancelled their contract with the centre-back after seeing the footage.

However, Zouma was still selected by Hammers manager David Moyes for the 1-0 Premier League win over Watford on Tuesday after the player said he was "deeply sorry" for his actions.

Deschamps also strongly criticised Zouma but refused to rule out selecting him for international duty.

"I was very surprised by Kurt," Deschamps said on France 3. "This is something that is inadmissible, intolerable, and cruelty without a name.

"These images are shocking and unbearable."

He added: "I'm not a prosecutor. I am here to make selections on different criteria.

"It's happened to me before that players who have made mistakes have not been selected for a while. I will not change my way of doing things for the next squad."

Zouma has been capped 11 times at international level and was part of France's Euro 2020 squad.

The defender has played 15 times for West Ham this season as Moyes' side push for a top-four finish in the Premier League as well as a deep run into the Europa League.

The Montreal Canadiens have fired head coach Dominique Ducharme, with former Hall of Famer Martin St. Louis replacing him on an interim basis.

Ducharme, 48, was dismissed following a 7-1 rout at the hands of the New Jersey Devils, with Montreal rock-bottom of the league. 

That defeat means Montreal have lost 30 of their 45 games this season, the most of any NHL team the campaign after making the Stanley Cup final.

St. Louis, 46, takes over as a head coach for the first time in his career, having previously held the position of consultant with the Columbus Blue Jackets in the 2018-19 campaign.

"We are very happy to welcome Martin to the Canadiens organisation," general manager Kent Hughes said in a statement.

"Not only are we adding an excellent hockey man, but with Martin, we are bringing in a proven winner and a man whose competitive qualities are recognised by all who have crossed his path."

Hughes released another statement thanking Ducharme for his work over the past year, having stepped into the role of head coach in February 2021.

"We would like to sincerely thank Dominique for his work and contributions to the Montreal Canadiens organisation," Hughes said. 

"At this point in the season, we felt it was in the best interest of the club to make a change."

St. Louis' NHL career saw him play a combined 1,134 games for the Calgary Flames, Tampa Bay Lightning and New York Rangers, racking up 391 goals and 642 assists in that time.

Montreal are on a run of seven consecutive defeats – and 13 from their past 14 games – and have conceded 33 times in their most recent five outings, leaving their new head coach with a mountain to climb to turn things around.

Iranian Alpine skier Hossein Saveh Shemshaki has been provisionally suspended after becoming the first athlete to return a positive doping test at the 2022 Winter Olympics.

The International Testing Agency (ITA) confirmed on Wednesday that Shemshaki, who was due to compete in his third Games, tested positive for an anabolic steroid.

Shemshaki, 36, returned an "adverse analytical finding" in an out-of-contest test on Monday, the ITA said.

"The athlete is prevented from competing, training, coaching, or participating in any activity, during the Olympic Winter Games Beijing 2022," the ITA added in a statement.

"The athlete has the right to challenge the imposition of the provisional suspension before the Court of Arbitration for Sport – Anti-Doping Division (CAS ADD). 

"The athlete also has the right to request the analysis of the B-sample."

Shemshaki was Iran's flag bearer at Sochi 2014, where he took part in the slalom and giant slalom events, as he did four years earlier in Vancouver.

Los Angeles Lakers coach Frank Vogel has not ruled out a trade involving Russell Westbrook ahead of Thursday's deadline.

Nine-time NBA All-Star Westbrook missed his first game of the season on Wednesday as the Lakers fell to a 107-105 defeat against the Portland Trail Blazers.

The 33-year-old's absence was put down to a back injury sustained the previous evening against the Milwaukee Bucks.

Westbrook spent the final quarter of that game watching from the sidelines, having earlier been jeered by his own fans, and later questioned Vogel's rotation policy.

That has done little to help the relationship between Westbrook and Vogel, with strong suggestions the 2017 MVP could be on his way out.

And rather than put an end to those rumours on the back of the defeat to Portland, Vogel instead offered a rather cryptic response.

Asked if there is a chance Westbrook will not be a part of the team once the trade deadline passes, Vogel said: "If there's a way to improve our team, we'll improve our team. 

"I've got nothing else to say about the trade deadline."

Westbrook, traded to the Lakers from the Washington Wizards last August, has 1,006 points for the season, a tally bettered only by LeBron James (1,133) among Lakers players.

But Westbrook's 18.3 average through 55 games is his lowest since 2009-10, and down from the 31.6 managed with Oklahoma City Thunder in 2016-17 when crowned MVP.

He was on court for just 26 minutes against the Bucks prior to hinting at his displeasure with Vogel, who in response insisted no player is bigger than the team.

"The needs of the team always come first," he said on Wednesday. "We have to be willing to do whatever it takes to get the Lakers a win. 

"Sometimes he's going to be in there for that, sometimes he's not."

The Lakers have now lost six of their last eight games and are 26-30 for the season, with a winning percentage of .464 placing them ninth in the Western Conference.

James, who top-scored for the Lakers against the Trail Blazers with 30 points, admitted the trade rumours are having a negative impact on his side.

"Obviously it's something that's weighing on this group that we're trying to all get through," he said.

"It almost feels like fog in the air and we're all trying to see what's on the other side of it."

Chloe Kim made history by becoming the first woman to win two Winter Olympics gold medals in the snowboard halfpipe event despite what she described as "the worst practice ever".

The American managed an incredible score of 94.00 on her opening run which ultimately proved enough to claim gold nearly four points clear of Spaniard Queralt Castellet (90.25), who claimed the silver, and nearly six ahead of Japan's Sena Tomita (88.25), who earned the bronze.

The 2018 gold-medallist looked to further etch her name into the history books in her second and third runs by attempting 1260s – a trick that has never been landed at a women's halfpipe event – but was unable to make it stick.

Kim, who became the youngest woman to win an Olympic gold medal in snowboarding four years ago at the age of 17, explained that her first-run performance surprised her after a difficult practice session and that her high score granted her the freedom to try the 1260s.

"I was so proud of myself," Kim said. "I had the worst practice ever. I probably landed my run twice when I'm used to landing it eight times, normally, and so that puts you in a weird headspace. It felt so inconsistent.

"I didn't want to feel all that pressure of having to land my first safety run [in competition]. I overflowed with emotion when I was able to land it on the first go, and it opened up a lot of opportunity for me to go try something new.

"[Progression] is so important and after I put down the first run, I got two attempts at landing the cab 1260. I'm super proud of myself for going out and trying to do it.

"I'm looking forward to being able to land it at the next one. Now I'm so eager to see my family, my boyfriend, my dog. Then I will feel all the feelings and be proud of myself."

Kim spent 19 months away from snowboarding in 2019-20 but returned to the sport last year, claiming a sixth X-Games crown and a second World Championship gold.

The 21-year-old revealed that she was feeling the positive impact of sports therapy and felt in a stronger mental state for this year's Games and beyond.

"I am more prepared this time," Kim continued. "Luckily, it was a learning curve since the last time.

"Now that I've grown up a little more and I understand boundaries and I have an amazing therapist, so I think it will make the journey a lot more doable."

Russell Westbrook played no part as the Los Angeles Lakers fell to a 107-105 defeat against the Portland Trail Blazers on Wednesday.

A day after hinting at his unhappiness at coach Frank Vogel, and with lingering doubts over his future ahead of Thursday's trade deadline, Westbrook watched from the bench.

It is the first game the nine-time All-Star has missed all season, though Vogel could at least still call upon the likes of LeBron James and Anthony Davis from the beginning.

James scored 30 points for the Lakers, who led 54-47 at half-time, only for the depleted Trail Blazers to slowly turn things around before rallying in the fourth quarter.

Anfernee Simons led the scoring for Portland with 29 points, while Jusuf Nurkic added 19 points and 12 rebounds as the hosts held on to snap a six-game losing streak.

Bogdanovic and Mitchell inspire Jazz to victory

The Golden State Warriors' nine-game winning streak was ended in emphatic style as they fell to a 111-85 defeat to the Utah Jazz.

Without the injured Rudy Gobert for an eighth game, the Jazz were inspired to victory by 23-point Bojan Bogdanovic and Donovan Mitchell, who had 14 points and 10 rebounds.

The Warriors, without Klay Thompson, Andre Iguodala and James Wiseman, finished with a shooting percentage of 36 per cent in what was their heaviest defeat of the season.

DeRozan stars again

Five-time NBA All-Star DeMar DeRozan was serenaded by "MVP!" chants after scoring 36 points in the Chicago Bulls' 121-109 victory over the out-of-form Charlotte Hornets.

DeRozan hit 30 points for a fourth game running, during which time he has averaged 37.5 points, while Nikola Vucevic finished with 18 points, 15 rebounds and eight assists.

Elsewhere on Wednesday, Darius Garland's 27 points on his return from a back injury helped the Cleveland Cavaliers to a 105-92 win against the San Antonio Spurs.

The Toronto Raptors beat the Oklahoma City Thunder 117-98 for their seventh straight win and the Sacramento Kings were 132-119 victors against the Minnesota Timberwolves.

The Los Angeles Rams' preparations for the Super Bowl have been efficient, but they haven't been without issues, albeit relatively minor ones.

Southern California is in the grip of unusual heat for February and the Rams' matchup with the Cincinnati Bengals at SoFi Stadium could be the hottest Super Bowl ever.

Yet the Rams did not feel the full effect of the heatwave at their base in Thousand Oaks, which was hit by winds of around 22 miles per hour during Wednesday's practice.

With those winds expected to increase in strength, the Rams are moving practice for Thursday, by which time head coach Sean McVay will hope to have his voice back.

"I feel great, I just sound like s***," McVay said in Wednesday's media conference after it became evident he had lost his voice.

"Hopefully, we'll get this voice to come back, but it was like yesterday I was in my office for a minute then I went to talk to some of the coaches and then my voice sounded like this, I'm like 'what the hell happened?' I've got the honey, I've got all the remedies. We'll get this voice back."

Undeterred by his vocal cords failing him, McVay also has little qualms about switching practice to Pasadena to escape the difficult conditions.

"We're going to go practice at the Rose Bowl tomorrow, kind of anticipating the winds," he added. 

"If that's the biggest inconvenience of playing the Super Bowl playing at home that we have to get on a bus, we do that pretty regularly anyways going down to SoFi."

An outwardly optimistic person, McVay's swiftness in brushing off such inconveniences is no surprise, and the speed with which the Rams have installed their Super Bowl gameplan can only have helped his mood.

McVay, according to the pool report, said after practice: "Today kind of represented the finality of it. We can tweak and adjust as we go, but they [the players] did a good job of getting ahead of stuff.

"Guys felt really good. We ran through all the different situations that can come up…and then the next couple of days we'll just be tightening up."

McVay will be able to make any tweaks knowing that he will likely have all three of his top running backs available, with Darrell Henderson Jr. appearing poised to return from a knee ligament injury.

"I think Darrell’s going to go," said McVay. "So, you'll have Cam [Akers], Darrell and Sony [Michel]. You'll be able to see a good, three-back rotation, based on how the game unfolds.

"The situations that arise will dictate which one you're seeing. Like anything else, if we're able to get into a rhythm running it, we're going to go with the hot hand."

McVay might be straining to communicate but, with his running back room returning to full health and the gameplan ready, there's every reason for him to be confident of a career-defining victory that would taste as sweet as his honey remedy.

Casper Ruud began his Argentina Open title tilt with an impressively routine defeat of Roberto Carballes Baena.

The Norwegian, who is the top seed, saw off his opponent 7-6 (7-2) 6-3 to set up a quarter-final clash with home hopeful Federico Coria, who defeated Dusan Lajovic 4-6 7-5 6-4.

Ruud was taking to the court for the first time since being in ATP Cup action in early January, with ankle injury ruling him out of the Australian Open.

But on the scene of his maiden ATP title win in 2020, Ruud – who has won five tournaments since – looked in good shape.

"I feel, obviously, very good in Buenos Aires. I was a bit nervous coming back because it's the first time I have to defend a title," he said.

"Everything is a bit different since two years ago. When I won here it was a surprise. I was young.

"[This] was a good start. First time playing on clay in six months, so everything is a bit new again.

"Of course, I prefer to play on clay, but it takes some time to get used to the court and playing points."

Third seed Lorenzo Sonego also advanced through to the last eight in straight sets, the Italian beating Sebastian Baez 6-3 6-3 to set up a meeting with Fernando Verdasco.

Unseeded Spaniard Verdasco, seeking an eighth career title, progressed thanks to a hard-fought 2-6 6-3 7-5 win over Thiago Monteiro.

At the Dallas Open, John Isner won his opening match on home soil with a 7-6 (7-1) 6-7 (7-9) 7-6 (7-5) victory over Kevin Anderson.

Isner will next take on either Vasek Pospisil or Jurij Rodionov, with the qualifiers scheduled to meet on Thursday.

Marcos Giron and Jordan Thompson are also in the quarter-finals after seeing off Liam Broady and Brandan Nakashima respectively.

Wayne Rooney insisted his focus remains on Derby County but acknowledged he would "love" to manage Manchester United or Everton in future.

Rooney has overseen a tumultuous period at the Championship club, who were docked 21 points earlier this season due to financial mismanagement.

In the challenging circumstances at Pride Park, Rooney has excelled and the Rams are now just four points away from escaping the relegation zone with 16 games left.

Derby's survival hopes were boosted after both Peterborough United and Reading lost on Wednesday, while the former England striker was attending the premiere of his Amazon documentary, 'Rooney'.

His progress has already been noted by those at Goodison Park, with the 36-year-old claiming he turned down the opportunity to interview for the Everton manager's job last month as he did not want to walk away from Derby.

But Rooney would be open to joining one of his former clubs after he has navigated his current challenge with Derby.

"I didn't go to the [Everton] interview, which I was asked to go to," Rooney said on the red carpet at his film premiere. "I've always been one who likes a challenge and is willing to put the work in and fight.

"I've stood in front of my players and told them, 'I'm with you, trust me, I'm fighting with you'... what type of person would I be if, at the first opportunity, I left them?

"True to my word, I am fighting for the club. I am trying to get us out.

"And then Everton, Manchester United – two clubs close to my heart. Of course, one day I'd love to manage either of them clubs."

Derby cruised to a 3-1 victory over Hull City on Tuesday and next visit Middlesbrough, with Rooney believing his side's performances are resonating with the unwavering Rams support.

While he was overseeing yet another Championship victory, United were held to a 1-1 draw at lowly Burnley, but Rooney called for patience at his former club.

"I obviously haven't seen the [United] game – we [Derby] were playing. But I've seen the result and I think they're going through a tough period," he added.

"And you can see a few things off the pitch. It's a tough one. I think it's been going on for a while, if I'm being honest. These are things I brought up in 2010.

"They've tried everything. They've tried very experienced managers in Louis van Gaal. They've tried Jose Mourinho, David Moyes, Ole [Gunnar Solskjaer] – one of their own – and now they've tried more of the 'professor' type in the new manager.

"I really think they need to bring someone in and give them time. Give them the opportunity to build the squad, let them compete and get back to the levels we all think they should be at."

Pressed on potentially becoming the United manager, Rooney replied: "As I've said before, Manchester United and Everton are both clubs I'd love to manage one day, but I've got a commitment to Derby County.

"I'm fighting for them, so my focus has to be on Derby."

The rollercoaster that was the San Francisco 49ers' 2021 season was one in which calls to go with Trey Lance over Jimmy Garoppolo were frequent. However, former Niners head coach Steve Mariucci believes it will ultimately be beneficial for last year's third overall pick that Kyle Shanahan resisted those calls.

San Francisco enjoyed a turnaround to finish 10-7 after a 3-5 start to make the playoffs, where the Niners upset both the Dallas Cowboys and Green Bay Packers en route to the NFC Championship Game.

However, the 49ers let slip a 10-point fourth-quarter lead against the Los Angeles Rams in a 20-17 defeat in which Garoppolo failed to move the ball on each of the final two drives, defeat clinched with an interception on a desperate heave under pressure that will likely be the last throw of his Niners career.

Lance made two starts in relief of an injured Garoppolo but only took snaps in four games beyond those appearances, serving as a spectator for the entirety of the postseason.

With Garoppolo expected to be traded and hand the reins to Lance for 2022 and beyond, Mariucci expects the man San Francisco traded three first-round picks to acquire to be better positioned to handle the challenges he will face as a starting quarterback because of his time on the sideline.

"In some ways, Trey Lance will be a rookie again from a playing standpoint," Mariucci said at a pre-Super Bowl media event on Wednesday.

"The best thing for a player is to get on the field and play when it counts and that's in a game. The good news for him is he's had a year of sitting and watching a veteran prepare, learning the system, learning pro defenses, learning all these disguises and these crazy blitzes that he didn't see against South Dakota State, and that's a plus for him.

"He'll be more ready to do this when he gets his chance next year."

Lance was arguably the most athletically gifted quarterback in the 2021 draft class, with his abilities with his legs set to add another element to head coach Shanahan's already dynamic offense.

Referencing two quarterbacks he coached during his time with the Niners, Mariucci added: "I think the playbook is going to be a little bit different, they're going to use his legs moreso than they did Jimmy, with some zone-reads and some quarterback type runs and some movement and some keeps and some 'get em out there'.

"[It's a] little bit like when Jeff Garcia or Steve Young played, you change the launchpoint, it's all over the place, makes him more difficult to defend, and he's going to make first downs with his legs too.

"This year was beneficial for him from a learning standpoint and next year here's going to show us what he's got, I can't wait."

Aston Villa manager Steven Gerrard was thrilled by the performances of Philippe Coutinho and Jacob Ramsey in Wednesday's draw with Leeds United, convinced the latter will be an England international before long.

Villa played out a gripping 3-3 draw with Leeds at Villa Park, the visitors fighting back despite finding themselves 3-1 down at half-time.

Coutinho and Ramsey were crucial to Villa's lead – the Brazilian cancelled out Daniel James' early opener with a well-placed finish before setting up each of Ramsey's goals, both of which were well-weighted throughballs for the surging youngster.

It was the first time Coutinho has had a hand in at least three goals in a single game since August 2020, when he helped Bayern Munich to their remarkable 8-2 demolition of his parent club Barcelona in the Champions League – you have to go back to December 2019 for the last such instance that occurred in a league match.

Coutinho's struggles since leaving Liverpool have been well-documented, with the talented attacking midfielder struggling to find his niche at Barca and Bayern, but Gerrard is enjoying watching his old team-mate again.

He said: "Looking at Philippe's performance tonight, not just his goal and assists, if you don't love watching that you shouldn't be watching football.

"That was absolutely beautiful, some of the stuff he has done.

"It was vintage Philippe Coutinho tonight. He's certainly getting back close to where he was when the whole world was speaking about him.

"He's still got improvements to do from a physical point of view but in terms of his technical ability, you don't play for Brazil that many times or become a global superstar without that talent.

"He will get better and better. He is a joy to work with."

Ramsey, 20, is still waiting for recognition at international level with England, though Gerrard – who represented the Three Lions 114 times – is adamant the gifted midfielder is on the cusp of a call-up.

Gerrard did not want any comparisons made between himself and Ramsey, though he reckons the Villa academy product "is right up there" in terms of the standard of players he featured alongside.

"Listen he's not following in anyone's footsteps, Jacob Ramsey is Jacob Ramsey," Gerrard continued.

"He's going to be a terrific player and it won't be too long before the whole country are watching him, I'm sure, because he's in a top place.

"I know the level of the England players, I've been around it, and have enough experience to know it's only a matter of time but let's all be sensible and keep calm about it.

"I want him to make his own headlines with his football. He is a top talent, I'm loving every moment of working with him. He is getting stronger with each game because we're giving him the platform to express himself. He is in a wonderful place."
