Joey Carbery and Robbie Henshaw have been omitted from Ireland's Six Nations squad but the uncapped Jamie Osborne has been included.

Carbery has been seen as the long-term successor to fly-half Johnny Sexton, who will retire after the Rugby World Cup in France this year.

There is no place for the Munster number 10 in Andy Farrell's 37-man Six Nations squad, though, as Ross Byrne and Jack Crowley were given the nod as back-ups to captain Sexton.

Centre Henshaw has endured an injury-hit season and is currently sidelined with a wrist problem, so he was overlooked by head coach Farrell.

Fellow centre Osborne, 21, is the only uncapped player in the squad as the top-ranked team in the world target a first Six Nations title in five years.

Ireland start the tournament with a trip to the Principality Stadium for Warren Gatland's first game since returning for a second spell as Wales head coach on February 4.

Farrell said: "The Six Nations is a huge competition for us and another opportunity for us to grow as a group. 2022 was a busy year as we got to work with a larger group of players as we continued to build our squad depth and competition for places.

"While there are a few players carrying knocks and others that have missed out on selection for the start of the tournament, they will have the opportunity to push their case playing for their provinces in the URC over the coming weeks as no doubt we will need to call upon the wider group as the tournament progresses."

Ireland squad:

Forwards: Ryan Baird, Finlay Bealham, Tadhg Beirne, Jack Conan, Gavin Coombes, Caelan Doris, Tadhg Furlong, Cian Healy, Iain Henderson, Rob Herring, Ronan Kelleher, Dave Kilcoyne, Joe McCarthy, Peter O'Mahony, Tom O'Toole, Andrew Porter, Cian Prendergast, James Ryan, Dan Sheehan, Josh van der Flier.

Backs: Bundee Aki, Ross Byrne, Craig Casey, Jack Crowley, Keith Earls, Jamison Gibson Park, Mack Hansen, Hugo Keenan, Jordan Larmour, James Lowe, Stuart McCloskey, Conor Murray, Jimmy O’Brien, Jamie Osborne, Garry Ringrose, Johnny Sexton (captain), Jacob Stockdale.

Casper Ruud followed Rafael Nadal out of the Australian Open and admitted his decision to play through much of December rather than have an off-season may have been a mistake.

The Norwegian second seed, who reached finals at the French Open and US Open last year, had been hoping for another deep run this fortnight, only to run into an in-form Jenson Brooksby.

After a 6-3 7-5 6-7 (4-7) 6-2 defeat in three hours and 55 minutes on Rod Laver Arena, Ruud was asked about his decision to head to Latin America for a lucrative exhibition jaunt with Nadal at the end of the 2022 campaign.

He planned to take a break in February instead, but can now begin that early after going out in round two in Melbourne.

The same goes for top seed Nadal, who was already heading for defeat to Mackenzie MacDonald on Wednesday before an injury compounded his misery.

Ruud's initial reaction to being questioned about his busy December was to be defensive, saying: "It's very easy to sit here now and say that was bad for maybe both Rafa and I due to the fact that we lost early here.

"At the same time, I see no reason why we couldn't have a good Australian Open or made better results down here. I think it's coincidental sometimes."

He spoke of the talent among fellow tour players making every player vulnerable, and the "small margins" between victory and defeat.

Asked whether he had any break at all, Ruud outlined how he left for the Latin America trip on November 21 and returned in early December, before heading off on a week's holiday to the Maldives. He then stopped for a training block in Abu Dhabi on the way home and played two matches at the Mubadala exhibition event.

At the end of this season, Ruud might insist on a longer break and a focused training block.

"It was maybe not enough to be able to perform well here this year," Ruud said. "So it will be considered by me and my team what we will do in December this year, and if this was the right way to prepare for Australian Open or not.

"Maybe it looks like it was not the right way, but there are many factors that come into play. I have done what I felt was the right preparation but wasn't able to perform and win as many matches as I hoped here this year."

Taylor Fritz and Alexander Zverev were sent packing from the Australian Open as wildcard Alexei Popyrin and lucky loser Michael Mmoh sprang major shocks.

Australian Popyrin said he was living a dream after beating the fancied Fritz in an epic second-round match lasting four hours and two minutes on John Cain Arena.

American Mmoh, whose mother has Australian citizenship, knocked out former world number two Zverev just moments later on Margaret Court Arena.

Their exits followed the shock defeat for second seed Casper Ruud earlier in the day, as Novak Djokovic's half of the draw lost a host of big names.

Wildcard Popyrin won 6-7 (4-7) 7-6 (7-2) 6-4 6-7 (6-8) 6-2 against American eighth seed Fritz, revelling in the chants of "Popy" from the crowd afterwards.

The 23-year-old was close to tears, his voice breaking, after reaching the third round of a grand slam for the fifth time.

"This win, it means so much to me," Popyrin said. "I had the toughest year last year, didn't win many matches. I've won as many matches this year as I won in the whole of last year, and it's only January.

"Pre-season I put my head down and worked as hard as I could. I don't want that feeling I had last year ever again.

"I wrote that down to myself in my head, and I'm going to keep working, I'm going to keep pushing, I'm going to keep trying to go all the way."

Addressing the crowd, Popyrin added: "I love this feeling. I want more of this feeling. I want you guys to have this feeling more. I love you guys so much, thank you."

He is coached by former top-20 star Xavier Malisse and felt the Belgian's influence against Fritz.

"I was playing four hours, and me and my coach were locked in, it was like two against one against Fritzy. We had the same thoughts all the time," Popyrin said. "This is the dream for me and I don't want to wake up at all."

Mmoh was beaten by Aleksandar Vukic in the final round of qualifying but received a call into the draw at the last minute, after a late withdrawal, allowing him to cancel a flight home.

The world number 109 will face fellow American JJ Wolf next, for a place in round four, having ousted 12th seed Zverev 6-7 (1-7) 6-4 6-3 6-2.

Mmoh's father, Tony, represented Nigeria and won a match at the Australian Open in 1988.

"Life is crazy," Mmoh said. "Right when you think everything is looking dim, everything is looking dark, there's light at the end of the tunnel.

"My week is proof of that. I could easily have been in the States, was ready to be in the States, had my bag packed, my flight booked, I was meant to leave yesterday morning. The fact I'm playing Margaret Court is insane.

"If you look at my box over there, there's about five to seven Aussies. I used to come every single Christmas to visit them, unfortunately my mum couldn't be here, I feel like I'm half Australian because of them and I love you guys. This is like my second home now so might as well make it a homecoming.

"It's the biggest win of my career hands down. Coming out I felt the nerves a little bit. I settled down at the end of the first, and at that point I told myself I shouldn't even be here. I told myself on match point if I get a chance just go for it, because I shouldn't even be here."

Nikola Jokic wants to be remembered as a "really good team player" after making franchise history in the Denver Nuggets' 122-118 triumph over the Minnesota Timberwolves.

The two-time reigning NBA MVP contributed 31 points, 13 assists and 11 rebounds as the Nuggets improved to 32-13 on the season to sit top of the Western Conference.

Jokic now has 3,686 career assists, surpassing the tally of Alex English who had 3,679 in Nuggets colours. Moreover, he has reached his tally in 568 games as opposed to English's 837.

English himself paid tribute to Jokic's achievement, intimating he foresees a third MVP accolade in the near future, posting on Twitter: "I knew that eventually my all-time assist record would be broken. I'm honored to see that it's 2 time, I mean 3 time MVP of the NBA do it. Congrats big fella."

Jokic was typically humble when asked what it meant to earn a piece of Nuggets history.

"When you have a lot of assists, it just shows that you're a good team player," he said.

"That's something I want to be. I want everybody to remember me as a guy who was a really good team player."

Team-mate Jamal Murray, who nailed a game-tying three-pointer with a little over two minutes remaining, then hit the bucket that put the Nuggets into a lead they did not let go of, said of Jokic: "We clapped a little bit. That's a lot of passes. That's pretty impressive."

The Nuggets are next in action against the Indiana Pacers, who are 23-23 and ninth in the Eastern Conference, on Friday.

LeBron James could do with a break, and Los Angeles Lakers coach Darvin Ham admits he fears he might be "running him into the ground".

James had 32 points, eight rebounds and nine assists in a 116-111 defeat to the Sacramento Kings on Wednesday, a third tight loss for the Lakers in their last four games.

They stand at 20-25 for the season, despite the impressive efforts of their talisman.

James has scored 30 points or more in 13 of his last 17 games, but the Lakers have only won nine of those contests.

He is taking on a heavy share of the burden in the injury-forced absence of Anthony Davis, who is expected back in action in February.

Only once in his last eight games has James spent less than 35 minutes on court, and Ham might have to do something about that.

Ham said: "I feel bad about that. He's playing at an amazing level, but we can't run him into the ground. That was one of my main goals coming into this season. Here he is with 36 and a half [minutes] again tonight.

"We just have to manage him and have clarity in terms of scaling back his minutes some. And with the non-game days, being smart. His preparation is always on point, but we can still hold him out of some things that we may do on the court.

"He's a high-IQ basketball player, so he understands he can sit there and watch something and have it all figured out defensively and offensively.

"It is a concern. My staff and I, we talk about it all the time. It's just tough because he's such a competitor. We're in these games and he wants to win and we want to win, so you kind of lose sight of the minutes until you come back and see the stats sheet after the game.

"You're like, 'Oh hell'. We're going to figure it out. We have a team of very smart people – our medical and training staff and our coaching staff.

"We all put our heads together and see what the best course of action is to give him whatever rest can be gained, not just going forward in the short term, but the long term as well."

De'Aaron Fox led the Kings with 31 points against the Lakers, and Sacramento have now won five successive games to improve to 25-18 for the season.

The Lakers will be back in action against the Memphis Grizzlies on Friday, with Ham looking for more from his team.

Ham said: "It sucks to lose these close games, but I still feel wholeheartedly at some point we're going to break all the way through. We're competing in my opinion at a very high level."

Rafael Nadal faces up to eight weeks out of action with the hip flexor injury he sustained on his way out of the Australian Open.

The defending champion and top seed in Melbourne was bundled out 6-4 6-4 7-5 by world number 65 Mackenzie McDonald on Wednesday, struggling to move around the court during the closing stages of the contest.

He refused to retire and afterwards confirmed he aggravated an issue he had been suffering with for a couple of days. The 36-year-old Spaniard knew the problem he had been suffering with for a "couple of days" had worsened, but he was unsure exactly what was causing it.

Now Nadal has clarity, receiving details of the injury after tests on Thursday.

He knows that provided all goes to plan, he should be back on court for the clay-court stretch in Europe leading up to the French Open, where the 14-time winner is also the defending champion.

Nadal wrote on Twitter: "Good afternoon. I have carried out medical tests after the defeat yesterday. The MRI shows a grade two lesion in the iliopsoas of the left leg. Now it's sports rest and anti-inflammatory physiotherapy. Normal recovery time six to eight weeks."

The 22-time major winner may struggle to get back to full fitness in time for the Indian Wells and Miami Masters 1000 events in March.

Those are due to be preceded on his schedule by a high-profile exhibition match in Las Vegas against Carlos Alcaraz on March 5; however, both men are presently injured, raising doubts over whether that will go ahead.

Nadal was distraught to suffer yet another injury setback, after severe foot and abdomen problems hit his 2022 season.

"In terms of sports and in terms of injuries and tough moments, I mean, that's another one," Nadal said on Wednesday. "I can't say that I am not destroyed mentally at this time, because I will be lying."

LaMelo Ball is confident his latest ankle injury will not keep him out long despite exiting the Charlotte Hornets' 122-117 win over the Houston Rockets on Wednesday.

Ball hurt his left ankle for the third time this season in the third quarter when team-mate P.J. Washington landed on him as both jumped to block a Jabari Smith shot.

The Hornets point guard and 2020 NBA Draft third pick overall remained on the ground in pain and appeared unable to bear weight on his left leg as he was helped to the locker room. He was ruled out with a "left ankle sprain".

"I can walk and everything, so I'll just take it day by day and see what it is," Ball told reporters.

"I feel a little better. It don't feel like them other ones so I think I'll be straight."

The game was only Ball's 21st this season, enduring an interrupted campaign where he is averaging 24.0 points, 5.4 rebounds and 8.4 assists.

Ball said he would not require an MRI scan while Hornets head coach Steve Clifford was a bit more circumspect.

"We'll see how he feels tomorrow and that's really it," Clifford said.

Casper Ruud made two grand slam finals last year, but his 2023 Australian Open campaign fell to pieces with a shock second-round loss to 22-year-old Jenson Brooksby.

American Brooksby prevailed on his fifth match point, after fluffing three in the third set, when second seed Ruud hit a return long. That sealed a 6-3 7-5 6-7 (4-7) 6-2 victory in three hours and 55 minutes on Rod Laver Arena.

Ruud's demise on Thursday means he joins top seed Rafael Nadal in exiting early in Melbourne, with the Norwegian departing in the Spaniard's wake after struggling through the first two sets before a medical time-out prior to the third.

Ruud staved off three match points at 5-3 down in the third, when Brooksby got tight with victory in sight, before winning the set in a tie-break.

However, Brooksby regained his composure in the fourth set and broke twice early to open up a 3-0 lead, barely looking back.

Brooksby's triumph is the biggest of his career, having only ever previously beaten one top-10 player, Stefanos Tsitsipas, at last year's Indian Wells. It also provides an early highlight in Brooksby's first Australian Open, having missed out in 2022 after testing positive for COVID-19 on the eve of the tournament.

"I was just really proud of my mental resolve after that third-set battle didn’t go my way," Brooksby said during an on-court post-match interview. "I thought I was playing really strong. I didn’t want to lose my focus out there."

Ruud, who was the runner-up at both the 2022 French Open and 2022 US Open, could not match Brooksby's 50 winners, while the Norwegian committed 55 unforced errors. He also failed to capitalise on Brooksby's unconvincing 57 per cent first-serve percentage.

Data Slam: Americans maintain winning form in men's singles

Brooksby's triumph sets up a third-round date with compatriot Tommy Paul as the Americans continue to make waves in the men's singles draw. It was another American, Mackenzie McDonald, who upset Nadal on Wednesday, while a flood of US stars have reached the third round.

ACES/DOUBLE FAULTS

Brooksby – 2/2
Ruud – 5/4

WINNERS/UNFORCED ERRORS

Brooksby – 50/48
Ruud – 33/55

The Memphis Grizzlies' achieved a franchise record 11th straight win with Desmond Bane and Ja Morant starring in a thrilling 115-114 victory over the Cleveland Cavaliers on Wednesday.

Darius Garland had a three-point shot on the buzzer blocked by Dillon Brooks, after Steven Adams tipped in with 16 seconds left after Morant's miss.

Bane top scored for the Grizzlies with 25 points, including five-of-eight three-point shooting. Morant added 24 points with eight assists for Memphis, who improved to 31-13, along with 20-3 at home.

Morant had spent time in the locker room in the first quarter after copping a knee to his neck, but re-entered the game in the second quarter.

Game-winner Adams scored 13 points with 10 rebounds and four assists, while Jaren Jackson Jr had an excellent all-round game with 15 points, seven rebounds, two steals and four blocks.

Memphis also managed an 11th consecutive game with 115 or more points.

The Cavs were missing Donovan Mitchell due to a groin strain, with Garland top scoring with 24 points on five-of-11 three-point shooting along with 14 assists.

Caris LeVert added 23 points with four rebounds and six assists, with power forward Evan Mobley scoring 18 points and bringing down 15 rebounds with two blocks. The Cavs are now 28-18.

Trae downs Doncic as Hawks win fourth straight

The Atlanta Hawks continued their run of momentum with their fourth straight win in a 130-122 victory over Luka Doncic's Dallas Mavericks.

Dejounte Murray scored 30 points, making four-of-six three-pointers, while John Collins added 19 along with 18 from Trae Young plus 12 assists, as the Hawks secured a season-best four-game winning streak to move above .500 at 23-22.

Doncic, who was traded as a top-five pick for Young at the 2018 NBA Draft, scored 30 points for the Mavs, but only 11 after quarter-time, while he gave up seven turnovers.

Jokic adds another franchise record in Nuggets win

Nikola Jokic recorded his 14th triple-double of the season as he surpassed Alex English for the most assists in franchise history in the Denver Nuggets' 122-118 win over the Minnesota Timberwolves.

The MVP candidate finished with 31 points, 11 rebounds and 13 assists, going past English's 3,680-assist franchise record with a dime for Kentavious Caldwell-Pope.

Jamal Murray added 28 points for the Nuggets, who secured their eighth straight win and 15th successive victory at home to remain top in the west, at 32-13.

Boston Bruins head coach Jim Montgomery heaped praise on Patrice Bergeron but says he will undergo X-rays after copping a puck to the face in Wednesday's 4-1 win over the New York Islanders.

Bergeron headed down the tunnel early in the third period after a deflected slap shot from David Pastrnak missed his visor and hit him in the face.

The Bruins captain was in apparent pain, having medical attention, but would emerge back on the bench later in the period, helping his side round out a third straight win.

Despite returning to the ice, Montgomery revealed Bergeron had not been cleared by medical staff yet.

"How much respect I have for him coming back after, I know the puck got deflected, but it hits him up high and in the face," Montgomery told NESN.

"The admiration I have and everybody has for him coming back to try to help the team win after that is immense.

"We're hoping that all the X-rays come back good."

The Islanders had taken a first-period lead from Zach Parise but Bruins defensemen Charlie McAvoy and Derek Forbort responded with goals 4:12 apart in the second period to claim the advantage.

Brad Marchand and Trent Frederic added third-period goals for Boston with Charlie Coyle having two assists, while goal-tender Linus Ullmark made 25 saves in his 100th career win.

"I couldn't be more happy, it's been overwhelming," Ullmark said. "I have a lot of gratitude playing with the boys who work so hard every night."

The Bruins are the NHL's only 30-win team, improving their record to 35-5-4.

Buffalo Bills head coach Sean McDermott revealed Damar Hamlin has returned to visiting the team's facility "almost daily", offering a major boost ahead of their AFC Divisional round game against the Cincinnati Bengals on Sunday.

Hamlin was discharged from hospital last week after being in a critical condition having suffered a cardiac arrest in the January 2 game against the Bengals in Cincinnati.

The Bills safety continues to progress on his road to recovery, which McDermott outlined ahead of their rematch against the Bengals for the first time since the incident.

"Damar is in the building now, almost starting daily," McDermott told reporters. "So that's good news. As he continues to improve, that certainly helps.

"That experience, we'll carry that with us. There's a challenge to that, but there's also a lot of good that comes with that. Right now, we need to focus on the positives that came out of that as opposed to the other piece of that."

McDermott said Hamlin's participation was still "limited", not partaking in team meetings or anything physical.

"He comes in and really just started today or yesterday and just trying to get back to a little bit of a routine and just get himself acclimated again and taking it one step, one baby step at a time here," he said.

"Kind of get himself dipping his toe back in here and you know, getting on the road to just getting back to himself."

It remains unclear if Hamlin will attend Sunday's game at Bills Stadium, having watched Sunday's 34-31 victory over the Miami Dolphins remotely.

Bills quarterback Josh Allen added that the players were boosted by Hamlin's return and the emotional trauma of the incident was easing to an extent.

"I think there's honestly not too much left over," he said. "Obviously with guys being able to see Damar, guys being able to see him and talk with him, that alleviates most of that.

"I'm not saying there's going to be none, I can't speak for everyone on the team, but we're extremely focused right now, having a good week of preparation. We'll try to go out there on Sunday and execute."

The Bengals enter the Divisional round game on a nine-game winning streak, seeking back-to-back AFC Championship Game appearances. Since Week 9, Cincinnati have the third best points per game and second best points per game differential in the NFL.

Despite that, the Bills are regarded as favourites for the game, given their emotional lift, home ground advantage and having finished as the AFC second seed, but Bengals head coach Zac Taylor does not view his side as underdogs.

"We know that we're the defending AFC champions," Taylor told reporters. "There's an edge to this team, we're not an underdog. That's been the feeling the whole season. We know we belong in the field with every team."

Los Angeles Chargers coach Brandon Staley was never concerned about losing his job even after his team's historic collapse in a playoff loss to the Jacksonville Jaguars on Saturday.

Asked during Wednesday's season-ending news conference if he ever felt his job was in danger, Staley responded bluntly: "No."

While the Chargers are keeping Staley on the job, they did fire offensive coordinator Joe Lombardi and quarterbacks coach/passing game coordinator Shane Day on Tuesday.

"I have a lot of confidence in how we do things here and what we've been able to accomplish and that's the truth," Staley said.

"Everybody that's been around me on a day-to-day basis knows that. I am aware of the speculation … but I was not worried about that because I know what goes on here on a day-to-day basis. I know what we have in our locker room. I know what's out on that field and I'm excited to keep going."

Staley guided the Chargers to a 10-7 record this season and their first playoff berth since 2018. He is 19-15 in two seasons as head coach.

Former New Orleans Saints coach Sean Payton is rumoured to be ready to get back into coaching and the Chargers would've been considered a prime landing spot with quarterback Justin Herbert emerging as a top player at the position.

Payton has already met with the Denver Broncos and Houston Texans and will soon meet with the Carolina Panthers, according to reports.

Despite Staley's success, he received criticism after he decided to play starters in the regular-season finale despite having already clinched the No. 5 seed right before kick-off. Star receiver Mike Williams suffered a back injury in that game that forced him to miss the playoff loss to Jacksonville.

That decision was only made worse when the Chargers blew a 27-0 lead to the Jaguars in a 31-30 loss that kept Los Angeles without a playoff victory since 2018.

Staley was asked if Jaguars coach Doug Pederson outcoached him.

"I wouldn't say that was the case for a half," he said. "That team that we were playing showed a lot of fight, a lot of resilience. I thought it was a high-quality game against two teams that are both young and hungry. I thought it was just a high-level game all around."

Eddie Jones will make an immediate impact on his return to Australia, for which "there was always writing on the wall", according to former England captain Chris Robshaw.

Jones was dismissed by England in December but replaced Dave Rennie as the Wallabies' coach on Sunday, taking up a role he previously held between 2001 and 2005.

Defeats in November to France, Ireland and particularly Italy proved the final straw for New Zealander Rennie, paving the way for Jones to return in time for the 2023 Rugby World Cup.

The Australian was in charge when the Wallabies lost to England in the 2003 World Cup final, and Robshaw always expected Jones to return in a bid to complete unfinished business.

Speaking on behalf of Sage, powering the Smart Ball at the Six Nations, Robshaw told Stats Perform: "He was a proud Australian man and I think there was always writing on the wall that one day he will be back in Australia coaching.

"They're in a bit of a tough place in terms of their confidence. They had a tough tour in England, and it's no doubt he'll be able to go and shake things up and have an immediate impact.

"It is his man-management, which is brilliant, and his ability to get the best out of people because they have a good team and they have some good players.

"But how do you turn it around quickly and generally? That's all kind of up in the air."

Jones will aim for glory at the World Cup in September, having led both Australia and England – in 2019 – to the final as well as defeating South Africa with underdogs Japan in 2015.

Former British and Irish Lions captain Sam Warburton believes Jones wants to be on the biggest stage to shine, as does Warren Gatland, who made a similar return to retake the role as Wales coach.

Warburton said: "I like him, and at least in the same way as Warren [Gatland], they're international coaches. They need that international kick.

"I can't imagine Eddie being a club coach anymore, same with Warren. I think Warren wanted to just be back in the international helm and Eddie wants to be back in the international helm.

"In front of 80,000 people, he will turn to a press conference of people talking about pressure, he'll be laughing inside, he wouldn't be doing the job this long at such a high level if he didn't truly love it.

"I really respect him. He's gone straight back into the deep end with international rugby with Australia, and he's got a World Cup; that's what he needs to thrive, so it is not really surprising.

"If you said in the Autumn Series, Warren Gatland and Eddie Jones are going to clash somewhere in the World Cup, then you'd be thinking how was that going to be. 

"I don't think anyone would have thought it would have been Wales and Australia. Compared to where we were three months ago, it is a great story, and it's going to develop a great subplot going into the group stage of the World Cup."
