Marc Marquez has been ruled out of next weekend's Argentina Grand Prix after undergoing surgery on his hand.

The six-time MotoGP champion suffered a fracture to the first metacarpal bone in his right hand in Sunday's Portuguese Grand Prix.

Repsol Honda confirmed on Monday that Marquez was operated on at the Ruber Internacional Hospital in Madrid and will spend a short period recuperating.

As a result of sitting out the next round in Argentina, the Spaniard will also miss the double long-lap penalty imposed on him by the FIM 

Marquez was found guilty of irresponsible riding in Portimao when ploughing into Miguel Oliveira at Turn 3 early in the race, resulting in both riders dramatically crashing out.

The 30-year-old also forced Jorge Martin wide, which saw his compatriot lose several positions.

Speaking after the race, which he entered in pole position, Marquez accepted blame for the collision that cut his opening race of the season short.

"The most important is that Miguel is okay," he said. "I made a big mistake on Turn 3, in the first part, and this created everything.

"I braked and had a massive lock with the front tyre. That meant that I released the brakes. My intention was to go to the left side. 

"But the bike stayed on a lean and I couldn't avoid going to the right side. I was able to avoid Martin but couldn't avoid Miguel. I was very worried because the contact was big.

"I already said it personally – but I want to say sorry to him, to his team, to the Portuguese fans. 

"I have been penalised for that mistake with a double long lap penalty, that I completely, completely agree."

It will be interesting to see whether a passionate Denver Nuggets crowd follows coach Michael Malone's lead on Monday when Joel Embiid comes into town.

Embiid is Nikola Jokic's rival in an NBA MVP race that Malone believes has taken "a really ugly, nasty turn".

"It's like when I was a college coach, all the negative recruiting," Malone said last week, having described Embiid as "a great candidate".

"It's not promoting my guy. It's ripping down every other guy. And that's just ridiculous.

"Celebrate them; don't criticise, don't tear them down. Build them all up. And whoever wins it, good for them."

The Nuggets and Embiid's Philadelphia 76ers have been fighting for position in their respective conferences, but debate around the top individual award has continued to rage.

For his part, Jokic has tried to set it aside. "I don't think about it anymore," he said.

But it is easy for the two-time reigning MVP to take that stance. Giannis Antetokounmpo is on the periphery of the conversation – albeit perhaps less so after losing to the Nuggets at the weekend – and he won the two before Jokic.

Embiid has been a finalist the past two years but has never been named the MVP. He might have a different view of things.

For that reason, the 76ers superstar should relish the opportunity to go into Denver and upset the top seed in the West.

Embiid has already landed a big blow in one game against the Nuggets this season, finishing with 47 points and 18 rebounds in the Sixers' win back in January.

That was only the 15th instance of such a performance in the regular season since the NBA/ABA merger, with others to achieve that feat including Antetokounmpo, Michael Jordan and, on three occasions, Shaquille O'Neal.

Yet for all Embiid's dominance, that game also illustrated how he and Jokic are so different.

That is no secret, with Jokic a center like Embiid but possessing the playmaking skills of an elite point guard, but it has only become clearer this year.

Embiid has a usage rate of 37.4 per cent, nudging above last year's mark for a career high. It is little wonder then when he has games, as against the Nuggets, in which he attempts 31 field goals. He has twice attempted 32 field goals this season.

It is that volume shooting that allows Embiid to lead the league in scoring (33.3 points) despite ranking 'only' 23rd in field goal percentage (54.5). It also helps that he is the only player making more than 10 free throws per game (10.2) – albeit he made just seven of 10 against the Nuggets.

Meanwhile, Jokic is averaging 24.9 points, down on the previous two seasons. He scored 24 against the 76ers.

But this is in line with his usage rate shrinking considerably to 27.3 per cent after peaking at 31.8 per cent in 2021-22 – and Jokic could scarcely be more efficient with those possessions.

He leads the Nuggets in both points and assists (9.9), as well as rebounds (11.8), just as he did in the 76ers game (nine assists, eight rebounds). His turnover percentage is up slightly (16.6) – there were seven against Philly – but so is his assist rate (45.5 per cent) and his shooting from the field (63.3 per cent), three-point range (39.0 per cent) and the foul line (82.3 per cent).

Jokic is right there for a season averaging a triple-double. That has only been done – four times – by one player in the modern NBA. In those seasons, Russell Westbrook's usage rate never dipped below 30 per cent. He also averaged at least 4.5 turnovers per game in each year, with Jokic back on 3.5.

Embiid, who likewise has 3.5 turnovers, carries the 76ers' burden in scoring and rebounding, but James Harden is the team's creative force. He had 13 assists against the Nuggets.

What the 76ers big man lacks in eye-catching passes, however, he makes up for on the defensive end. Defensive metrics do not really do justice to the gap between Embiid and Jokic.

But that is not to denigrate Jokic. In truth, given their extraordinary seasons, there are no shortage of numbers that would support the case for one man or the other – perhaps contributing to the nastiness Malone bemoaned.

Maybe it is best then that it comes down to a matchup on the court, two weeks out from the end of the regular season.

Might we see another 40-point Embiid night to clinch a first MVP? Or Jokic's latest triple-double that pushes him towards three in a row? Whoever wins it, as the Nuggets coach said, good for them.

The Tampa Bay Rays are "optimistic" emerging shortstop Wander Franco will be available for their Opening Day game with the Detroit Tigers on Thursday despite a quad injury concern.

Franco, 22, underwent an MRI on Sunday which Rays manager Kevin Cash said returned "favourable" results.

Despite the good results, Cash said Franco would not play in Tampa Bay's spring training game against the New York Yankees on Monday but was hopeful of their season opener against the Tigers.

"We've got three days to treat him," Cash told the Tampa Bay Times. "I don't think anything's been decided.

"We're optimistic that if we can get this thing treated the right way, we should be in a spot where he's good to go.

"Three days off in a row for him. Maybe get him out there that last day and take [batting practice] and see how he feels, but I'm pretty optimistic."

Franco had been scratched from the lineup for Saturday's spring training game against the Boston Red Sox due to right quadriceps soreness, although the Rays called that precautionary.

The 22-year-old has been a revelation for the Rays since debuting in 2021, including tying Frank Robinson (1956) for the longest on-base streak (43 games) in AL/NL history by a player 20 years old or younger.

Franco finished third in AL Rookie of the Year voting in 2021, before hitting .277 with six home runs and 33 RBIs in 2022.

The New York Yankees have announced top prospect Anthony Volpe will start at shortstop on Opening Day against the San Francisco Giants on Thursday.

The 21-year-old had been invited to spring training as a non-roster player and has won the initial battle with Oswald Peraza for the starting shortstop role.

Volpe batted .314/.417/.647 with three home runs and 10 extra-base hits in 17 games during spring.

"He's earned the right to take that spot, and we're excited for him and excited for us," Yankees general manager Brian Cashman said of Volpe.

"He just dominated all sides of the ball during February and March, and that bodes well, obviously, for him as we move forward."

Yankees manager Aaron Boone delivered the news on Sunday, with the franchise releasing the video on social media.

"My heart was beating pretty hard," Volpe said. "Incredible. I'm just so excited. It's hard for me to even put into words."

Volpe will become the youngest Yankees shortstop since Derek Jeter debuted at 20 in 1995. He enjoyed a standout 2022 in the minors that ended at Triple-A, having been selected by the Yankees with the 30th overall pick in the 2019 MLB Draft.

The Yankees topped the American League East last season with a 99-63 record before being swept by the Houston Astros in the AL Championship Series.

The team re-signed Aaron Judge, Anthony Rizzo and Gleyber Torres in the offseason, while pitcher Carlos Rodon signed after opting out of his Giants contract.

Jason Kidd was hopeful Luka Doncic would have his one-game suspension overturned as the Dallas Mavericks work to "stop the bleeding" after a fourth straight defeat.

The Mavericks' past two losses have come against a 25-51 Charlotte Hornets team who looked to have shut down for the season.

And Sunday's 110-104 reverse, which left Dallas 11th in the West at 36-39, included a further costly setback.

Doncic received his 16th technical foul of the season after directing a profanity at an official following a correct no-call, meaning he is set to be banned for Monday's game at the Indiana Pacers.

The Mavs superstar had been the centre of attention following the previous game, too, outlining his "really frustrating" situation on a misfiring team.

Doncic responded with 40 points, 12 rebounds and eight assists, but his suspension now presents a problem for a team who cannot afford to throw away another game in an intense playoff chase.

"You're never going to replace him. It's going to take a group," coach Kidd said.

"It's 'next man up' mentality with Timmy [Hardaway Jr.] and look at [Jaden] Hardy and Josh [Green] participating and playing more minutes, [Justin] Holiday playing more minutes.

"But hopefully it's rescinded. I didn't think it was warranted, but we'll see what happens.

"If he is suspended, we have to move on with the next guy, so Timmy, coming back from the flu, was really good tonight, Holiday's minutes were positive, Maxi [Kleber] did a great job, a lot of great jobs.

"I thought Luka, again, being able to do what he did after his press conference... I thought he would have a big game and he did.

"It's just unfortunate we let these two games go. We've got to figure out how to stop the bleeding."

Top seed and reigning champion Carlos Alcaraz dished out a bagel as he continued his outstanding form with a straight-sets victory over Dusan Lajovic to ease into the Miami Open fourth round on Sunday.

Alcaraz, who triumphed at last week's Indian Wells Open, beat the 76th-ranked Serbian 6-0 7-6 (7-5) in one hour and 32 minutes.

The 19-year-old Spaniard hit 26 winners compared to Lajovic's eight, while Alcaraz also sent down three aces on a 75 per cent first serve percentage.

Alcaraz won the first frame to love in 32 minutes, registering his fourth career bagel at ATP Masters 1000 level, equaling the most by a teenager alongside Rafael Nadal.

The world number one will face 2023 Australian Open semi-finalist Tommy Paul in the fourth round after the American got past 20th seed Alejandro Davidovich Fokina 6-3 7-5.

Third seed and 2022 Miami Open finalist Casper Ruud blew a first-set lead to lose 3-6 6-4 6-4 to Botic Van De Zandschulp.

The Dutchman improved his head-to-head record against Ruud to 3-1 with his first-ever top five win, with the Norwegian left to lament converting only two of 15 break points.

Ninth seed Taylor Fritz progressed into the fourth round with a 6-4 6-4 win over Denis Shapovalov, improving his head-to-head record against the Canadian to 4-5. Fritz committed only eight unforced errors and did not face one break point.

Jannik Sinner maintained his excellent hard-court form with his 18th win this season on the surface, as he defeated Grigor Dimitrov 6-3 6-4 in one hour and 28 minutes. The Italian 10th seed will be Andrey Rublev in the next round.

Sixth seed Rublev needed less than an hour to get past Miomir Kecmanovic 6-1 6-2, while compatriot Daniil Medvedev advanced via a walkover against Alex Molcan due to a right hip injury.

Seventh seed Holger Rune cruised past Diego Schwartzman 6-4 6-2, while Finland's Emil Ruusuvuori got past Taro Daniel 6-3 7-6 (7-3).

Pittsburgh Steelers head coach Mike Tomlin remains thrilled about drafting quarterback Kenny Pickett to be the future of the franchise, highlighting his excitement heading into year two.

Pickett, 24, was the first quarterback selected in the 2022 NFL Draft, and the only player at his position to get picked in the first two rounds.

He ended up starting 12 games in his rookie season, and while he finished with more interceptions (nine) than passing touchdowns (seven), his team managed to go 7-5 with him under center.

Pickett's completion percentage of 63.0 was the 15th-highest ever for a rookie quarterback, and he showed off some impressive wheels, with 55 carries for 237 yards and three touchdowns on the ground.

He continued to improve as the year went on as well, recording wins in each of the last five games he played where he attempted more than one pass.

At the league's annual owners meetings on Sunday, Tomlin spoke about how impressed he was with the former Pittsburgh Panthers star, who shared a practice field with the Steelers during his college career.

"I'm excited about Kenny individually in terms of the growth that he's capable of making and, and what he's willing to do to realise that," he said.

"I think I'm probably more excited about that because I've just been around him intimately now for 12 months. 

"There were some anticipation things because of the close proximity [in college] that we've all talked about quite a bit, but the reality of having worked with him for 12 months, it's just more evidence of what we should be excited about – his willingness to work, his professional approach, his maturity in processing. It's exciting."

There were questions about the Steelers' decision to retain offensive coordinator Matt Canada, but Tomlin said he is hoping the continuity and not forcing Pickett to learn a new offense will only be positives.

"I think it's reasonable to expect that [continuity] to be significant," he said. "But we'll have an opportunity to make it so."

Despite missing the playoffs in 2022 by going 9-8, it continued the Steelers' incredible streak of 19 consecutive seasons without a losing record.

Denver Broncos starting wide receiver tandem Courtland Sutton and Jerry Jeudy will not be on the trade block as the team looks to recuperate some draft equity, according to head coach Sean Payton.

The Broncos gave up both their first and second-round picks for this April's NFL Draft in their blockbuster trade for former Seattle Seahawks quarterback Russell Wilson, also sending away their first, second and fifth-rounders last year.

It means Denver will not make their first selection until early in the third round, and rival teams are aware Payton may be looking to wheel and deal in his first offseason in charge of his new team.

While that may be the case, Payton took the opportunity on Sunday to reassure his top pass-catchers that they will be sticking around this year.

"I see and read just like everyone else does," he said. "Then occasionally, when someone really crowds the plate, I throw a fastball right at their chin, and they back up, and they're like, 'All right.' 

"So, I haven't thrown any fastballs lately, but we're not trading those two players."

Payton said he understands why rumours are swirling – with ESPN reporting Denver would consider an offer for Jeudy if it involved a first-round pick – but pointed out they are not interested in getting worse in the short-term.

"When people call and the phone rings like it does this time of year, [general manager] George Paton's job is to pick it up and say, 'Hey, tell you what, we're not [interested]'," he said. "And so, we've received calls, you bet.

"Those are two good football players. But we're in the business of gathering talent right now. Why do people call? Because they know we're void of draft picks and that we might, because there was some discussions a year ago, I think, regarding Courtland. But we like the current group that we're working with."

The Broncos are entering a crucial second season with Wilson at the helm, and the franchise are desperate to see a return to form from the former Super Bowl champion.

Wilson went 4-11 in his 15 starts, while posting the lowest touchdown total (16), the worst completion percentage (60.5 per cent), and lowest QBR (36.7) of his career, while absorbing a career-high 55 sacks. It was the first season since 2016 that he was not selected for the Pro Bowl.

Aryna Sabalenka needed just 68 minutes to dispatch Marie Bouzkova 6-1 6-2 in Sunday's third round of the Miami Open.

Sabalenka hit 26 winners in the victory and now has 250 at WTA 1000 level for the season, representing one of only two female players with more than 200 in 2023.

The world number two, who is the top seed in the tournament after Iga Swiatek's withdrawal, has now won 19 of her past 21 matches, with her only losses in that span to Elena Rybakina and Barbora Krejcikova.

She will get the chance to avenge that loss to Krejcikova next after the Czech Republic representative knocked out hometown star Madison Keys 7-6 (7-4) 6-3.

Former French Open winner Krejcikova registered her 10th WTA 1000 level win against Keys, becoming only the second player to achieve that this season.

Former Australian Open champion Sofia Kenin fell 6-4 6-4 to Canada's Bianca Andreescu, who continued her strong run after previously knocking out seventh seed Maria Sakkari and 2021 US Open champion Emma Raducanu.

In a serve-dominated match, 2019 US Open champion Andreescu sent down seven aces, maintaining 70 per cent first serve percentage.

Ninth seed and former Olympic gold medallist Belinda Bencic was eliminated 7-6 (10-8) 6-3 by 18th seed Ekaterina Alexandrova, who will take on Andreescu in the next round.

Marketa Vondrousova won her all-Czech matchup against 17th seed Karolina Pliskova, and their compatriot Petra Kvitova enjoyed a 6-4 7-6 (7-3) triumph over recent Monterrey Open champion Donna Vekic.

Romania's Sorana Cirstea made it seven wins from her past eight matches with a 7-5 6-1 result over Karolina Muchova, having knocked off fifth seed Caroline Garcia in the second round.

Varvara Gracheva ensured a strong day for the Russians with a 6-1 6-2 demolition of Magdalena Frech in a battle of two unseeded players.

LeBron James revealed the full extent of the injury that kept him out of the Los Angeles Lakers' previous 13 games before Sunday's return, but said he may still require surgery.

James returned off the bench with 19 points, making six-of-11 shots from the field with eight rebounds and three assists in 30 minutes as the Lakers lost 118-108 to the Chicago Bulls on Sunday.

The four-time NBA MVP revealed after the game that he had actually torn a tendon in his foot against the Dallas Mavericks on February 26, which typically keeps players out for longer than the four weeks' recovery time he needed.

The 38-year-old said he was told by two doctors that he required surgery but opted against it, albeit conceding he may still require an operation on the injury in the offseason.

When asked why James opted against surgery, he replied: "Because I went to the LeBron James of feet and he told me I shouldn't."

James added: "Right now I don’t need it [surgery]. We'll wait and see. I'll probably get another MRI at the end of the season and go from there.

"If I end up having to get surgery after the season... by the time next season starts I'll be fine, I'll be ready to go."

The Lakers provided few updates during his recovery, with his return coming with minimal advance warning.

James added that doctors told him he was "healing faster than anybody they've seen before with the injury", leading to his early comeback, although he said he would remain "day to day" in the short term depending on his recovery.

"I felt confident in the workouts that I had this week," James said. "The day after the workouts, when I woke up, stepped out down off the bed, I could possibly play today. After my workout early before the game today, I knew I could play."

On his performance, James added: "I felt okay. Obviously the rhythm is the most important.

"I had a couple of drives and the ball got away from me and a couple shots didn’t feel as good as before, but I was out for four weeks obviously so between that and the wind I've just got to get those things back leading into the final stretch of the season."

James' return for the Lakers came with seven regular season games left, with the side having gone 8-5 in his absence to boost their playoff hopes.

"Now we're sitting with a chance to be a top-eight seed that definitely changed my mindset coming back and trying to be part of this obviously," James said. "I won't say changed, but enhanced it, in terms of my workouts and treatment. They played such great basketball."

James is averaging 29.3 points on 50 per cent shooting with 8.4 rebounds and 6.9 assists from 48 games this season.

The Lakers dropped below .500 with the defeat, sitting ninth in the West with a 37-38 record.

The five-seed San Diego State Aztecs are through to their first Final Four in school history after grinding out a low-scoring 57-56 win against the six-seed Creighton Bluejays in Sunday's Elite 8 action.

With their seasons on the line, the two sides combined to shoot a dismal five-of-30 (16.6 per cent) from three-point range, but there were no such struggles for Aztecs junior guard Lamont Butler.

Butler posted a game-high 18 points on eight-of-11 shooting, nailing both of his three-point attempts, while only committing one turnover in his 30 minutes.

Seven-foot-one Creighton center Ryan Kalkbrenner continued his strong NCAA Tournament with a team-high 17 points (eight-of-17 shooting), six rebounds and two blocks.

It was not without controversy though, as after Bluejays senior transfer Baylor Scheierman tied the game with 32 seconds remaining, San Diego State's Darrion Trammell was fouled on the potential game-winning floater with 1.2 seconds on the clock.

Creighton's players and coaches were apoplectic at the call, which was borderline, and after Trammell missed the first free throw, he drained the second to secure the one-point victory.

They will face this year's most unlikely Final Four participants next, with Florida Atlantic waiting in the wings after having never won a single game in the NCAA Tournament prior to this season.

Meanwhile, the five-seed Miami Hurricanes also booked their ticket to the first Final Four in school history after an 88-81 triumph over two-seed Texas.

The Hurricanes were coming off their first ever Elite 8 appearance in 2022, and they have gone even further this time around thanks in large part to the spectacular showing from senior wing Jordan Miller.

Miller scored a game-high 27 points – his highest total since November 2020 – while shooting a perfect seven-of-seven from the field and 13-of-13 from the free throw line.

All five of Miami's starters scored at least 11 points each, and they did it in old-school fashion, shooting 59 per cent from the field while only attempting eight three-pointers as a team.

The Hurricanes will meet the Connecticut Huskies in the Final Four, who are the only team seeded fourth or lower in NCAA Tournament history to win four games in a row by double-digits.

Anthony Joshua has set his sights on becoming a three-time world heavyweight champion "within the next 16 months" as he prepares to face Jermaine Franklin.

The 33-year-old is not currently in the title picture after losing back-to-back fights to Oleksandr Usyk in September 2021 and August 2022.

Joshua has tasted defeat in three of his past five bouts, with Andy Ruiz Jr sensationally ending his opponent's unbeaten streak of 22 fights.

But the Briton believes he is on the road back to the top, with a huge showdown against Tyson Fury again being touted should he overcome Franklin at the O2 Arena on Saturday.

"I do and I did want respect from people in the industry that I admire, ex-legends in the game and when you're not a champion any more you feel like that goes away," he said.

"That was definitely something I was yearning for – the respect from ex-champions. When I'd lost it, it was like 'f***, I've lost that invincibility', but it's all good.

“We move forward. I'm not really doing it for that purpose any more because I'm not in that position, but the desire? 

"One is definitely to become champion, which I think is possible within the next 16 months.

"I think we've got to see what happens this year with the belts. Let them be competed for and then potentially let them go up in the air and then we'll see where the belts land. 

"Then it's about just staying consistent, staying focused on improving for these next 12 to 16 months while I'm in title contention."

Next weekend's fight will be Joshua's first since 2015 that has not been contested with a world title on the line.

"There is definitely not as much nerves," he said. "That kind of pressure, that pressure cooker is off a bit. The pressure was a lot, I can't lie to you.

"But when you want something so bad, I was really pushing that undisputed narrative for so long, that road to undisputed hashtag with all of the brands we work with. 

"We pushed it, but now we're at a new stage. We can't look back. We're only looking forward and I see a bright future and that kind of keeps me in good spirits."
