Andrey Rublev made his fourth ATP Masters semi-final on Friday, dispatching Grigor Dimitrov in under 90 minutes at Indian Wells in a 7-5 6-2 win.

Dimitrov had only faced two break points for the tournament until this quarter-final, and Rublev capitalised when his opponent’s serve evaded him. Rublev was returning with particular focus, getting 85 per cent of points back across the court on Dimitrov's first serve alone.

Rublev broke in the fifth game of the first set on the back of two double faults, but Dimitrov secured one of his own with a trademark backhand pass. The 24-year-old Russian answered right back to regain breathing room and close out a tight first set.

Securing the break in the third game of the second, that consistent pressure on Dimitrov's serve again forced two double faults in the fifth game. From there at 4-1, Rublev saw the finish line.

The win was the seventh seed’s 13th in a row, adding Indian Wells to semi-final appearances at Miami, Monte Carlo and Cincinnati. A win in the final would equal a career-high 15 matches in a row undefeated.

"I think I played really well. In the beginning, it was more about who will be the first to dictate and play more aggressive, because both of us like to dictate with our forehand," Rublev said afterwards.

"The return [of serve] was one of the most important things. If you can bring as many returns as possible [into the court], and then here with these conditions, in some moments it's tough to serve."

In Friday's other quarter-final, Taylor Fritz did it tough against the unseeded Serbian Miomir Kecmanovic, winning 7-6 (7-5) 3-6 6-1.

While Kecmanovic was content playing defence and grinding from the baseline, Fritz was the more active and it was most apparent at 5-5 in the first set.

Down 0-30, Fritz stood and delivered from the middle of the baseline with a booming forehand, before securing a critical hold.

The difference in tactics showed in the eventual winner differential, with Fritz's 35 in comparison to Kecmanovic's 15. Despite Fritz's relatively low unforced error count, he still gifted Kecmanovic the second set, serving three consecutive double faults to surrender the break at 3-4.

He regrouped and reeled off the opening five games of the third set, setting up his semi-final with Rublev. The other semi-final will see Rafael Nadal and Carlos Alcaraz meet in an all-Spanish duel.

JuJu Smith-Schuster is leaving the Pittsburgh Steelers to join the Kansas City Chiefs, the wide receiver appeared to confirm.

The 25-year-old was expected to leave the Steelers and used his official Twitter account to post a goodbye message to the fans, before adding in a later post: "#ChiefsKingdom Let's Go!"

Smith-Schuster will receive a one-year, $10.75M deal in Kansas, according to reports.

He spent five years in Pittsburgh after being drafted from the University of Southern California, playing 63 games and making just one touchdown, which came against the Las Vegas Raiders in Week 2 of last season.

Smith-Schuster posted a screenshot on Twitter that read: "To all of Steelers Nation. Thank you for taking me in and making me a part of the family from the moment that I was drafted. You all took me in so quickly, and I really needed it.

"I was a wide-eyed 20-year-old who was sent to the east coast away from my family for the first time in my life, and you made me feel right at home, despite all of the loneliness I should have felt.

"These have been the best five years in my life. I owe so much to the fans who embraced me and who made playing on Sundays in Pittsburgh so special.

"It was an honor to wear the black and gold for you all! I love you! JuJu."

Stephen Curry's foot injury will be "re-evaluated in two weeks", the Golden State Warriors have revealed.

Curry sustained the injury in Wednesday's 110-88 defeat to the Boston Celtics, leaving the court in the second quarter after contesting a loose ball with guard Marcus Smart.

Reports on Thursday said the 34-year-old would be out "indefinitely", and the Warriors confirmed on Friday that the player has suffered a sprained ligament in his left foot after undergoing an MRI.

"Stephen Curry, who exited Wednesday's game vs. Boston with 4:09 remaining in the second quarter due to a left foot injury, underwent an MRI on Wednesday night," a tweet from the Warriors read.

"The MRI indicated that Curry suffered a sprained left foot ligament. He will be re-evaluated in two weeks."

Curry scored 47 points in his previous game against the Washington Wizards on Monday, and has averaged 25.5 points per game this season for the Warriors.

He broke Ray Allen's record for most career three-pointers in December, though this season his percentage from beyond the arc sits at 38.0, slightly down on his career average of 42.8.

Warriors head coach Steve Kerr criticised Smart for "dangerous play" in the incident, and the duo exchanged words on the sidelines shortly after.

Smart defended himself from Kerr's claims, stating that Curry's injury was "unfortunate" and that he was "not a dirty player".

Deshaun Watson has agreed to waive his no-trade clause to allow the Houston Texans to deal him to the Cleveland Browns.

Watson had appeared to have narrowed his choices down to the Atlanta Falcons and New Orleans Saints in his search to find a new team as his time with the Texans comes to an end.

The Browns who, along with the Falcons, Saints and Carolina Panthers, had met with Watson, had previously been reported to be out of the running.

However, on Friday ESPN's Adam Schefter and NFL Network each reported that Watson had changed his mind, instead electing to join the Browns, from whom he will receive a record-breaking new contract.

According to NFL Network's Ian Rapoport, the Browns have agreed to give Watson a fully guaranteed five-year, $230million contract. That figure is $80m more than the previous record for fully guaranteed money at signing.

The Texans, meanwhile, are set to receive five draft picks, including three first-rounders, in exchange for Watson.

Watson's arrival will clear the way for the Browns to move former first-round pick Baker Mayfield, the quarterback who himself this week requested a trade.

The NFL offseason is as exciting as it has ever been in 2022 – and several of the biggest moves have centred on the AFC West.

This was already one of the deepest divisions in football, headlined by Patrick Mahomes and the Kansas City Chiefs but also featuring the 2021 fifth seed Las Vegas Raiders and gunslinging Los Angeles Chargers quarterback Justin Herbert in its supporting cast.

But the lineup for next season promises to be even more enticing.

The Raiders have worked to make sure they have not been left behind by the big-spending Chargers, while the Denver Broncos have also made a significant move to climb into contention.

In fact, over the past two weeks, the Chiefs have perhaps been among the big losers – watching on while the rest of their division have been getting busy...

March 8: Russell Wilson (Seahawks to Broncos)

The NFC West was previously the standard-bearer for hugely competitive divisions, but the power shifted as its fourth-placed Seattle Seahawks traded superstar quarterback Wilson to the AFC West's fourth-placed Broncos. With Aaron Rodgers staying with the Green Bay Packers, when a move to Denver had been mooted, a big play for Wilson was vital if the Broncos were to make up a significant gap. The Super Bowl XLVIII champion has ranked fourth for both pass yards per attempt (7.83) and touchdown percentage (6.2) across his NFL career – a significant upgrade on the Broncos' 2021 QBs Teddy Bridgewater and Drew Lock.

March 10: Khalil Mack (Bears to Chargers)

With Herbert running the offense, the Chargers have moved to improve the other side of the ball – first by trading for edge rusher Mack. A second-round pick in this year's draft was the primary compensation for a six-time Pro Bowler, immediately boosting a unit that ranked 23rd in total defense (360.1 yards per game) and 30th in run defense (138.9) last year. Mack struggled with injuries in his final year with the Chicago Bears but comes in opposite Joey Bosa, who ranks third in the NFL for QB pressures (389) and sixth for sacks (58) since his 2016 debut; Mack is fourth (388) and seventh (57.5) over that same period.

March 14: J.C. Jackson (free agent to Chargers)

As well as draft collateral, the Chargers had salary cap to work with and sent a large chunk of it to cornerback Jackson, allowed to leave by the New England Patriots. Jackson had certainly earned his pay day, leading the NFL in interceptions (25) since debuting in New England in 2018. This playmaking ability was also illustrated by the 26-year-old giving up big plays on only 18.9 per cent of his targets last season, the eighth-best rate among corners with at least 50 targets.

March 15: Randy Gregory (free agent to Broncos)

The Chargers' edge-rushing duo will take some beating, but the Broncos upgraded in that position, too, by giving up to $70million to Gregory, who had been set to re-sign with the Dallas Cowboys. Gregory, who missed almost three full seasons due to violations of the NFL's substance abuse policy, had finally established himself as a starter in 2021 with career highs in sacks (six) and QB hits (17) playing opposite DeMarcus Lawrence. The 29-year-old linebacker will now be paired with Bradley Chubb, despite a return to Denver for Von Miller being floated earlier in the month.

March 16: Chandler Jones (free agent to Raiders)

Having seen their division rivals make big moves, the Raiders responded with a $51m offer to Jones, while trading Yannick Ngakoue to the Indianapolis Colts for corner Rock Ya-Sin. Ngakoue had 10 sacks and forced two fumbles in his sole season in Las Vegas, but Jones (10.5 and six) topped both figures for the Arizona Cardinals in 2021. In fact, since Jones came into the league with the Patriots in 2012, he leads both categories, with 107.5 sacks and 33 fumbles forced. Although now 32, he shows few signs of slowing.

March 17: Davante Adams (Packers to Raiders)

The most stunning move of the lot followed on Thursday, when Adams' refusal to play for the Packers on the franchise tag led to his trade to the Raiders for a first and a second-round pick in 2022 (22 and 53 overall). The deal suddenly gives Raiders QB Derek Carr arguably the best offensive weapon in the NFL – and one he can go to time and time again, given Adams was targeted on a league-leading 35.4 per cent of his routes in 2021, which yielded career highs in catches (123) and receiving yards (1,553). Fellow wideout Hunter Renfrow may now see less of the ball than in his first 1,000-yard season (1,038), but he should also benefit from the attention Adams inevitably draws. The Raiders already ranked sixth in passing offense (268.6 yards per game).

Nick Kyrgios should face "severe" disciplinary action after a ball boy was almost struck by the Australian's smashed racket, one of the best-known coaches in tennis has said.

American Brad Gilbert, a former tour player who has worked with stars including Andre Agassi and Andy Murray, was taken aback by the tantrum from Kyrgios after a three-set defeat to Rafael Nadal in Indian Wells.

Kyrgios went to the net to shake hands with Nadal, who won 7-6 (7-0) 5-7 6-4 to reach the semi-finals.

But moments later he thrashed his racket against the ground. It bounced up high, travelling half the length of the court and causing a ball boy to take evasive action, stepping out of the way to avoid being hit and potentially hurt.

Kyrgios scornfully answered reporters' questions about the incident after the match, describing it as "a complete accident".

However, the 26-year-old unmistakably lost control in front of a full stadium and could face punishment as a result.

Gilbert wrote on Twitter: "Ridiculous to do that after such a good match, the penalty should be severe."

Gilbert questioned whether that would happen, given the ATP, which runs the men's tour, only handed a suspended eight-week ban to Alexander Zverev, plus a fine, after the world number three violently hit his racket against an umpire's chair.

"Unfortunately ATP lost the plot with Zverev situation and not a good look for kids and our sport," Gilbert wrote.

The 60-year-old Gilbert, who also coached Andy Roddick, said there was "absolutely no reason to snap on court after the match".

He added: "The stick could have easily gone anywhere like the stands and hit someone, seriously awful to see that in front of great crowd."

Kyrgios posted an exchange of text messages with the ball boy, and said he would give him a racket as a token of apology.

Saying sorry for the incident, Kyrgios wrote: "Didn't want it going anywhere near you to be honest."

Sergio Perez believes "it makes sense to have a discussion" around the idea of Formula One drivers being allowed to race with coronavirus.

The 2022 season will be the third affected by COVID-19, already impacting the grid for Sunday's opener at the Bahrain Grand Prix.

Sebastian Vettel has contracted the virus, meaning he will be absent for Aston Martin, while Daniel Ricciardo missed the end of pre-season testing but has recovered to take up his McLaren seat.

Red Bull's Perez missed two races in 2020 due to COVID-19 and suggests drivers – already isolated within their cars during races – should not be ruled out if they are otherwise fit and healthy.

"Going forward, we should discuss whether we allow the drivers to race if the symptoms are mild," the Mexican said.

"The drivers can obviously be the judge, but I think it makes sense to have a discussion.

"There is only so much you can do. I think it's just luck-dependent. It is difficult to not do anything. I'm just very sorry for Seb and for Daniel, but it can happen to anyone."

Nico Hulkenberg, Aston Martin's reserve driver, has replaced four-time world champion Vettel this week.

Duke coach Mike Krzyzewski revealed his excitement heading into his final NCAA Tournament before bringing an outstanding 42-year tenure to a close.

'Coach K' is leaving Duke at the end of this season, having been the Blue Devils' coach since 1980.

Krzyzewski was denied a 16th ACC Tournament title with defeat to Virginia Tech in the championship game last weekend, but the possibility of a sixth national title remains.

The coach's final March Madness begins with his number two seed facing 15-seed Cal State Fullerton on Friday.

"I'm just going to go for it, and that's what I've tried to do all season long," Krzyzewski said. "I just want to be in the moment. I'm excited."

While Krzyzewski is looking forward to his 'last dance', he acknowledges the emotion around each game is trickier for his Blue Devils players to deal with.

"That's part of the thing this week, is to get them mentally fresh, not just physically fresh," the 75-year-old said.

"There's a lot of emotion with all my stuff, and it's over now. That's a lot for those kids."

The East Regional section of the tournament saw a big upset on Thursday with a 15 seed beating a two seed – Saint Peter's stunning Kentucky.

And Krzyzewski is well aware of the delicate situation Duke find themselves in as they seek to prolong his coaching career.

"Most of the time, they don't realise it's one-and-done until it's done," he said.

How does Formula One go about following up the epic 2021 season?

Well, until that stunning campaign stole the show, this year was long seen as the one to look forward to with the introduction of new regulations to encourage competitive racing right down the grid.

Lewis Hamilton might have expected a genuine challenge in 2022; instead, in the form of Max Verstappen, it arrived 12 months early.

Excitement for the coming campaign is therefore at an all-time high, with pre-season testing adding to the theory fans should expect the unexpected.

Forecasting the year ahead is tricky, but Stats Perform seeks to identify the key narratives to follow this season ahead of Sunday's 2022 opener in Bahrain.

Max vs Lewis again

For now at least, Verstappen and Hamilton will expect to be the title frontrunners, which should mean another classic campaign.

Verstappen had never even led the standings until winning last year's Monaco Grand Prix, the first of five consecutive Red Bull wins – including four for the Dutchman.

That sequence ended at Silverstone, where contact with Hamilton sent Verstappen into the wall and set the tone for the rest of a frantic season, in which the pair repeatedly went at one another, crashing at Monza.

A titanic back-and-forth deserved a better ending than to be decided by a contentious call from race director Michael Masi in Abu Dhabi.

Now, defending champion Verstappen can attempt to prove he is better than Hamilton regardless of that decision, while the Mercedes man seeks to show his class once again as he pursues a record eighth title.

The midfield challenge

The game-changing 2022 regulations sought to enforce "closer racing", meaning both Verstappen and Hamilton could come under threat rather than simply blowing away the competition.

Early signs are encouraging on that front, with the two title rivals name-checking Ferrari's superb pre-season showing in the past week.

A resurgent Scuderia represent an obvious danger to those two, but so too do McLaren, Ferrari's midfield neighbours in recent seasons.

Lando Norris had four podiums last season before tailing off to finish sixth in the drivers' championship – still two places ahead of team-mate Daniel Ricciardo, who endured a tough first year with the team despite a famous win at Monza.

Having been aided by changes to the car for 2022, it is up to Ferrari and McLaren to close the gap considerably to Red Bull and Mercedes.

George a genuine threat?

Of course, Verstappen and Hamilton might typically expect their biggest challenges to come from those in the same cars.

However, Sergio Perez played the role of supporting Red Bull team-mate brilliantly in some key moments last year, while Valtteri Bottas continued to do his own thing without worrying Hamilton.

How a change in the Mercedes garage alters things remains to be seen. Bottas has been replaced by George Russell, who will hope to quickly make his mark.

Russell deputised for Hamilton for a single race the year before last and impressed, so it will be interesting to see if he now intends to push his legendary colleague all the way or will initially settle instead for helping his title bid.

Impact of refereeing reform

It is not only the cars that have had a makeover this year, with the officiating structure reorganised in the aftermath of the criticism aimed at Masi.

He is out as race director, with two men, Niels Wittich and Eduardo Freitas, taking his place, while other changes include the introduction of a "virtual race control room" to "assist the race director in the decision-making process".

Whether these changes suitably appease the team principals, who grew increasingly furious with each controversy last year, remains to be seen.

All parties would agree they would rather see the championship decided on the track – but it is not always as straightforward as that.

Following an eventful, dramatic and – dare we say it – the best Formula One season to date, the 2022 campaign has plenty to live up to.

Lewis Hamilton is going in search of a record eighth world title at the second time of asking after missing out to Max Verstappen on the final lap of the final race in 2021.

Reigning champion Verstappen is himself seeking some personal history this coming campaign, which begins with the Bahrain Grand Prix this weekend.

Ahead of what will hopefully be an equally as gripping season this time around, Stats Perform picks out some of the key numbers.

Hamilton narrowly missed out on surpassing Michael Schumacher as F1's most successful driver, though he has not missed out on top spot in successive years since joining Mercedes in 2013.

Should he match his achievement from last year, Red Bull's Verstappen (25 years, two months) would surpass Fernandes Alonso (25y, 2m, 23 days) as the second-youngest multiple world champion, behind only Sebastian Vettel (24y, 3m).

Mercedes may have suffered disappointment last time out, but they still finished top of the constructors' standings for a record-extending eighth time in a row. They are one short of equalling Williams as the second-most successful team, though Ferrari (16) are still well out in front.

In terms of other team milestones, Bahrain will be the 250th GP Mercedes have competed in, while they are six fastest laps away from setting 100. McLaren, meanwhile, are seven podiums from reaching 500 in F1.

Joining Hamilton at Mercedes this season is compatriot George Russell, who along with McLaren's Lando Norris is aiming to become the first Briton other than Hamilton to win a race since Jenson Button in 2012.

Bottas is now at Alfa Romeo and is joined by Guanyu Zhou, who will be China's first ever representative on the grid, making them the 39th country to appear in F1. Indeed, it is the first time three Asian countries will be represented, with Alex Albon (Thailand) and Yuki Tsunoda (Japan) also featuring.

Now 14 years on from their most recent constructors' title, Ferrari will equal their worst-such streak – 15 years between 1984 and 1998 – if they again miss out this term.

Carlos Sainz is Ferrari's big hope and he has either matched or bettered his performance from the previous season – both in terms of points and position – over the past six years when racing for just one team.

While his title chances are slim at best, Fernando Alonso has the opportunity to become the driver with the biggest margin between F1 titles of all time, 16 years on from his most recent success. 

Twenty-two events are currently locked in the F1 calendar for this year, with Miami set to become the 77th different circuit used when it hosts its maiden GP in May. It will be the 11th different track used in the United States, which is the most of any country.

After signing a six-year, $120million deal with the Buffalo Bills, future Hall-of-Fame edge rusher Von Miller said it was far from an easy decision.

Miller finished 2021 with 9.5 sacks for the Denver Broncos and the Los Angeles Rams, racking up five for Los Angeles in the final four games of the regular season.

His strong play down the stretch carried into the Rams' triumphant postseason, Miller registering a sack in the wins over the Arizona Cardinals and Tampa Bay Buccaneers before sacking Joe Burrow twice in their victory over the Cincinnati Bengals in Super Bowl LVI.

He finished the season fifth among edge rushers with at least 100 one-on-one matchups with a stunt-adjusted pass rush win rate of 43.40, according to Stats Perform data.

When reflecting about his free agency, Miller said he was surprised with how difficult the decision was.

"I wasn't expecting it to be like that," Miller told reporters. "I was expecting you win the Super Bowl, you got your offers out here, where do you want to go, pick, go back to the Rams. But it was tough man, it came down to the very end.

"I feel like I let [the Rams] down – I feel like I'm breaking up with my girlfriend. That's just me and the way I go about my business. 

"But this was the one time in my life where I had to make a decision for me. I saw what makes Aaron Donald Aaron Donald, and it was hard to walk away from that.

"The only way you can walk away from that is to walk into something special. And what they're doing here is extremely special. 

"[The Bills are] gonna win a Super Bowl with or without me. They've built an amazing team."

Five-time All-Star Freddie Freeman will leave the reigning world champion Atlanta Braves for the Los Angeles Dodgers on a bumper multi-year deal according to ESPN.

The 2020 National League (NL) MVP has agreed to a six-year, $162million deal with the Dodgers after reaching free agency for the first time in his career.

The 32-year-old has spent his whole professional career with the Braves dating back to 2007, before guiding them to their first World Series triumph since 1995 last year.

California-native Freeman hit .300 with 31 home runs, 83 RBIs and a NL-best 120 runs in their triumphant 2021 MLB season.

The Dodgers' blockbuster move for Freeman follows lucrative deals for Trevor Bauer in 2021 and Mookie Betts in 2020.

Freeman had rejected the Braves' qualifying offer after his contract expired following the World Series triumph, before becoming a free agent in November.

The Braves had signed Matt Olson earlier this week on an eight-year deal, making Freeman's exit more probable, with the Tampa Bay Rays, Toronto Blue Jays and New York Yankees also pursuing him.

The Dodgers are yet to confirm the deal with the move subject to Freeman completing a physical.

"Did that really happen?" Dodgers manager Dave Roberts said on Thursday. "Once Atlanta made that deal for Olson, it kind of came to pass. We're a much better ball club today than we were yesterday."

After his elimination from the Indian Wells Masters, Nick Kyrgios fired back at a reporter who questioned him about an incident after the match where he launched his racket, almost hitting a ball-kid.

Rafael Nadal ultimately emerged victorious in the match 7-6 (7-0) 5-7 6-4, after shaking hands with Nadal and the match umpire, Kyrgios spiked his racket into the ground as he walked back to his bench.

Speaking with post-match media, Kyrgios was sarcastic and rude when questioned about it.

"That's a question you're going to say after a three-hour battle against Nadal – that's what you've come here with?" he said.

"What would you like me to say about it? Obviously was that my intention? No, because did I throw the racquet anywhere near him originally? It landed a metre from my foot and skidded and nearly hit him. I'm human. 

"Things happen like that obviously, it was a very misfortunate [sic] bounce. What do you want me to say? It was three metres away from the kid.
