Rafael Nadal has withdrawn from the Indian Wells Open as he continues his recovery from a hip injury.

Nadal sustained the injury during his straight-sets defeat to Mackenzie McDonald at the Australian Open in January, struggling to move around the court during the closing stages of the contest in Melbourne.

A day after that match, the Spaniard wrote on Twitter: "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."

It seems that Indian Wells, the first ATP Masters 1000 event of the season, has come too soon for the 36-year-old, and it remains to be seen if he will be able to compete at the Miami Open later in March.

The tournament's director, Tommy Haas, said on Tuesday: "We wish Rafa continued healing, and hope to see him back at the BNP Paribas Open next year."

Nadal reached the final of last year's tournament at Indian Wells, where he lost to American Taylor Fritz. 

He has won three titles at Indian Wells, but the last came back in 2013.

Nick Kyrgios has withdrawn from next month's Indian Wells Open as he continues to recover from knee surgery.

The 2022 Wimbledon runner-up has not been in action this season, having been forced to pull out of the Australian Open in January due to a small lateral meniscus tear.

Kyrgios underwent surgery soon after and was targeting the opening Masters 1000 event of the season at Indian Wells for his first tournament back.

However, event organisers confirmed on Monday the 27-year-old is still not ready to return.

"Nick Kyrgios has withdrawn from the 2023 BNP Paribas Open due to an ongoing knee injury," a statement read.

Indian Wells gets under way on March 6 and is followed by the Miami Open at the end of the month.

Kyrgios' last competitive singles match came in October at the Japan Open, which he withdrew from ahead of the quarter-finals.

The Australian, a two-time quarter-finalist on the hard courts at Indian Wells, has slipped down to 19th in the ATP Rankings.

Novak Djokovic says his participation at the Indian Wells Open and Miami Open is "out of his control".

Djokovic, who last month won the Australian Open to move level with Rafael Nadal on 22 grand slam titles, has not played since claiming the title in Melbourne.

The world number one was nursing a hamstring issue throughout the season's first major, but he confirmed at a press conference in Belgrade on Wednesday that he will return to action at the Dubai Tennis Championships next week.

Djokovic could not compete in the United States last season due to his COVID-19 vaccination status, though his brother Djordje has claimed the 35-year-old has applied for a "special permit" to enter the country.

He has received clearance from the tournament organisers to play at the two Masters 1000 events at Indian Wells and in Miami but now faces a wait to find out if the U.S. government will grant him entry.

"The process for that has started. It is out of my control now," Djokovic said.

"I'd love to play and I'm glad I received the approval of directors in Miami and Indian Wells. I hope the decision makers will give the approval."

On his progress on the injury front, Djokovic explained: "As for the injury I sustained at the Australian Open, it's healed, but I'm not 100 per cent yet.

"Things are looking very good. As a team, we made the decision to go to Dubai."

Djokovic has won the Dubai Tennis Championships five times, though the last of those titles came in 2020.

He was knocked out by Jiri Vesely in the quarter-finals last year.

Djokovic this week tied Steffi Graf on 377 weeks spent as world number one.

The outright record is set to become his next week, with Carlos Alcaraz unable to surpass him even if the young Spaniard wins the Rio Open.

Nick Kyrgios is aiming to return to action at Indian Wells after undergoing successful surgery on his knee, his manager Daniel Horsfall confirmed.

The 2022 Wimbledon runner-up was left "devastated" after being forced to withdraw from the Australian Open on home soil last week.

Kyrgios was ruled out of his home grand slam after an MRI scan on his knee revealed a cyst as a result of a small lateral meniscus tear.

He went under the knife on Monday and is now battling to be ready in time for the first Masters 1000 event of the season at Indian Wells, which starts on March 6.

"The surgery was a great success," Horsfall told Australian newspaper The Herald.

"We couldn't have been more pleased with the outcome of it. Now we will be pushing ahead for a speedy recovery and are aiming to see everyone at Indian Wells."

Kyrgios won the seventh ATP Tour singles title of his career in Washington last August and claimed the Australian Open men's doubles title with Thanasi Kokkinakis 12 months ago.

The 27-year-old, who has yet to play competitively this season, is a two-time quarter-finalist on the hard courts at Indian Wells.

Novak Djokovic is resigned to again missing marquee tournaments in the United States after confirming his stance on COVID-19 vaccinations remains unchanged.

The 21-time grand slam winner is set to sit out the Indian Wells Open and Miami Open after the US extended the requirement for all non-American nationals to be vaccinated.

Djokovic's participation at August's US Open may also be in doubt should those requirements, which are currently in place until April 10, continue to be extended.

But having also been forced to miss events in the likes of the US, Canada and Australia last year, Djokovic accepts he may have to do the same in 2023.

"I don't think there's anything official yet, so when it is we can speak about it," Djokovic told reporters on Thursday when asked about the US restrictions.

When told the rules have been certified by the US Transportation Security Administration, Djokovic replied: "I mean, if it is official then it is – what can I do? Nothing. 

"You know my position, so it is what it is. I'm hoping [to play], but if I can't go, I can't go."

Djokovic, cleared to compete in Australia this year, was speaking after defeating Quentin Halys 7-6 (7-3) 7-6 (7-5) in the last 16 of the Adelaide International.

The 35-year-old, who beat Constant Lestienne in straight sets in his opening singles match of 2023, trailed 5-2 in the first set but recovered well and then edged the second set.

"It was a great performance from my opponent today and I want to congratulate him for a great fight," Djokovic said in his on-court interview. "He played like a top-10 opponent. 

"He was serving big, hitting his spots and on a fast court like this it's tough to break, so two tie-breaks is a realistic score in today's match. I'm glad to overcome the challenge."

Djokovic will now face Denis Shapovalov, who saw off Roman Safiullin 6-4 6-3, for a place in the semi-finals.

"Denis is one of the most complete players out there," Djokovic said of his next opponent. "He has a very dynamic style of tennis. 

"I haven't played him for a while so I'm looking forward to it. Every match from here gets tougher."

Sebastian Korda also advanced on Thursday with a 6-4 6-4 victory against Roberto Bautista-Agut, while Jannik Sinner beat Thanasi Kokkinakis 7-6 (7-2) 6-4.

At the Maharashtra Open in Pune, top seed Marin Cilic withdrew from his quarter-final with Tallon Griekspoor due to a knee injury.

World number 95 Griekspoor will now face Aslan Karatsev for a place in the final.

Rafael Nadal and Carlos Alcaraz will be exchanging fierce right-handers and left-handers across the net when tennis visits a legendary Las Vegas boxing venue in March.

In the lead-up to the Indian Wells Open, the Spanish superstars will go head to head at the MGM Grand Garden Arena on March 5, it was announced on Tuesday.

The indoor venue has staged major fights featuring the likes of Mike Tyson, Floyd Mayweather, Canelo Alvarez, Manny Pacquiao and Tyson Fury.

Nadal, the record 22-time men's singles grand slam winner, will be facing current world number one Alcaraz in a clash of generations. Alcaraz does not turn 20 until May, while Nadal will be 36 in June.

The match will mark Alcaraz's return to action in the United States, six months after he triumphed at the US Open in New York to land a first slam title.

Already the youngest number one in ATP history, Alcaraz is expected to win many more majors, but he recently said he turns a "deaf ear" to comparisons between himself and Nadal.

"There is no point in comparing," Alcaraz told reporters. "It doesn't matter that now I am world number one, Rafa's entire career counts for a lot. It is a pleasure, for every tennis lover, to see Rafa on the court."

The Indian Wells action begins on March 8. Nadal beat Alcaraz in last year's semi-finals before losing to Taylor Fritz in the final, later revealing he played with a broken rib in the title match.

Simona Halep has withdrawn from the Miami Open after aggravating a thigh injury.

Former world number one Halep was due to face Australia's Daria Saville in the round of 64 on Thursday but felt unable to contest the match.

Halep said she sustained a thigh injury during her Indian Wells semi-final defeat to Iga Swiatek the previous week and it caused her discomfort again while training on Wednesday.

The 30-year-old two-time major winner expects to sit out the Charleston Open and will miss the start of the Billie Jean King Cup.

In a tweet posted on her official Twitter account, Halep wrote: "While I was practising in Miami yesterday I felt a sharp pain in my left leg.

"I had been struggling with the thigh since my semi-final in Indian Wells and hoped it would improve, but I went for an MRI last night and unfortunately it showed a tear.

"My body needs time to heal and as a result I will be out of competition for three weeks. This means I have had to make the super tough decision to pull out of Miami, Charleston and Fed Cup [Billie Jean King Cup].

"While it feels like really disappointing news to share, I am keeping the confidence from my great start to the year and am motivated to do everything to be ready for the clay-court season.

"Thanks for your continued support through the highs and lows."

Lucky loser Harmony Tan will take Halep's place in the draw.

Rafael Nadal is facing new injury concerns, after Taylor Fritz ended his unbeaten streak for 2022 in the Indian Wells Masters final on Sunday.

Having to take a medical timeout during his win in the semi-final against countryman Carlos Alcaraz, the 35-year-old was forced into another injury break against Fritz, before losing 6-3 7-6 (7-5).

Nadal, whose 2021 was halted mid-year due to foot injury after back pain at the start of the season, ultimately rued his inability to fully compete against Fritz.

"I had pain, honestly. I had problems breathing," he said post-match. "I don't know if it's something on the rib, I don't know yet. When I'm breathing, when I'm moving it's like a needle all the time inside. I get dizzy a little bit because it's painful.

"It's a kind of pain that limits me a lot. It's not only about pain, I don't feel very well because [it] affects my breathing."

Nadal's 20-match unbeaten streak for 2022, which saw him claim the Australian Open and Acapulco titles in the process, also came to an end on Sunday. The world number four said the streak ending before coming into the clay season provides particular sadness.

"Honestly, I wanted to make it perfect before clay. [It] has been very, very, very beautiful," Nadal said.

"Honestly, I am sad because the way I was not able to compete. It's tough to have these feelings….but in the final it's very, very ugly. But in sport it's not about talking of the past, we need to talk about today. And today is a difficult day for me. "

Nadal commended Fritz on the victory, however. The 24-year-old claimed his maiden ATP 1000 title despite carrying an ankle injury.

According to the 21-time grand slam winner, it is a sign of things to come from the American, who had to back up from a tough win over Andrey Rublev in the semi-final on Saturday.

"Victories like today help. He played well. He went through some great matches during this week I think, especially yesterday," he said.

"A lot of credit to him on the victory of yesterday. In my opinion, his victory of yesterday is much bigger than his victory of today because he had [a] much tougher opponent in from yesterday.

"He already played great matches in Australia, this year if I'm not wrong, against [Stefanos] Tsitsipas.

"It's obvious that he is improving. With this victory, it's a great start of the season for him. He will have a chance to be very close if not in the top 10 very soon."

Taylor Fritz had never experienced "worse pain in my life before a match" before overcoming an ankle injury to end Rafael Nadal's winning start to the season and win the Indian Wells Masters on Sunday.

The American 20th seed, who has never been further than the fourth round at a major, claimed a breakthrough maiden ATP Masters 1000 title with a 6-3 7-6 (7-5) victory over Nadal in two hours and six minutes.

Fritz, 24, was not sure if he would be able to take his place in Sunday's decider after tweaking his ankle in Saturday's semi-final win over Andrey Rublev which he battled in the lead-up.

The injury was far from ideal preparation coming up against the Spanish fourth seed, who was on a 20-0 run to start 2022 having won January's Australian Open for a record-breaking 21st career major.

"I can't even begin to describe how ridiculous it is that I was able to play how I could play today," Fritz said during his post-match on-court interview. "I've never ever experienced worse pain in my life before a match.

"If I knew it was going to be that bad, I wouldn’t have come out here [beforehand] because I think people saw it. I took a couple of change-of-direction steps and screamed.

"I was trying to act tough as I had cameras on me. It probably looked like I was over-exaggerating the pain with how loud I screamed when I felt it.

"We did a lot of work leading up to the match. I went through a roller-coaster of emotions before the match, from thinking there's no way I could possibly play then to doing so much work on the ankle and going out again hitting on one of the backcourts and being really happy, thinking I can play.

"Really it didn’t affect me out on the court. Unbelievable."

California native Fritz, who reached last year's Indian Wells semi-finals, admitted winning the event was a "childhood dream" and that it did not feel real.

"I'm going to have to hold back tears for every single interview I do and every on-court speech," he said. "This is going to be tough. I'm such a happy crier.

"This is one of those childhood dreams, winning this tournament especially, you never thought would come true. I keep saying 'no way this is real'."

The title is the biggest of Fritz's career to date, triumphing in his first Masters 1000 final, and becoming the first American men's champion at Indian Wells since Andre Agassi in 2001.

Fritz is also the youngest male champion at the event since Novak Djokovic in 2011 and achieved that by ending Nadal's career-best 20-match win streak, denying him a record-tying 37th ATP Masters 1000 title too.

"I've lost these matches against the big guys my whole life," Fritz said. "It's always felt like they're unbeatable. To do it on the biggest stage, there's no other way. To win a big title, I feel like you've got to beat the best."

Taylor Fritz spectacularly claimed his first ATP 1000 trophy on Sunday, defeating Rafael Nadal 6-3 7-6 (7-5) to win the Indian Wells Masters.

Having only won once in his previous five finals, against Sam Querrey at Eastbourne in 2019, the 24-year-old displayed distinct maturity under pressure despite carrying an ankle injury.

The Spanish world number four's undefeated streak coming into Sunday's final ended at 20 with the loss.

For Fritz however, his first Masters title coming in as many finals was difficult to process, especially against an opponent in Nadal in front of his home crowd.

"I've lost these matches against the big guys my whole life," Fritz said in his on-court interview. "It's always felt like they're just unbeatable, so to do it on this stage, you have to beat the best."

"This is just one of those childhood dreams, winning this tournament especially at Indian Wells. This is one of those childhood dreams that you just never think will come true. I just keep saying 'no way this is real'."

Both faced pressure under their respective serves, but Nadal ultimately failed to capitalise on opportunies, converting only twice out of a possible 10 break points.

His 34 unforced errors in comparison to Fritz's 22, in such a closely contested match, contributed to the eventual result.

Fritz overcame his ankle concerns to race to a 4-0 lead in the first set before Nadal, facing his own physical challenges, took a medical time-out after losing the first set.

Nadal saved a championship point to force a tiebreak in the second set. Reflecting the pressure he was under after going down a mini-break, though, the Spaniard's ground strokes teetered dangerously close to the baseline.

The 35-year-old even made rare approaches to the net to turn defence into attack, amid some thrilling exchanges from the baseline, but a scuffed volley from mid-court to set up another Fritz championship point was the last straw despite displaying his trademark doggedness.

Rafael Nadal extended his 2022 win streak to 20 matches and clinched a spot in his fifth Indian Wells Masters final after a thrilling three-set victory over compatriot Carlos Alcaraz on Saturday.

The fourth seed lifted in the final set to win 6-4 4-6 6-3 over 19th seed Alcaraz in three hours and 12 minutes, with Nadal to play American Taylor Fritz in Sunday's decider.

The match was played amid blustery conditions, particularly the second set, where debris flew on to the court regularly interrupting or delaying play, which appeared to impact Nadal more.

Alcaraz had more winners (41-24) but also more unforced errors (34-26), with Nadal finding another gear when it mattered in the final set.

Nadal's victory improved his record to 20-0 this season, earning him a fifth Indian Wells Masters final spot and his first since 2013. The Spaniard won the Indian Wells crown in 2007, 2009, 2013 and was runner-up in 2011.

The 35-year-old also clinched a berth in his 53rd Masters final, keeping him on track for a 37th title at this level. 

The 21-time major winner claimed the decisive break in the eighth game of the third set after a physio break for treatment on his back, before serving out to-love for victory.

"In the second, the conditions became crazy, honestly," Nadal said during his on-court interview. "It was not funny playing in this wind. In terms of tennis it was OK but in terms of stopping all the time, it was not good.

"In the third I think I played much better. I played much more aggressive. I am super happy. Being in the final means a lot to me."

Alcaraz had started the better to open up a 2-0 lead in the opening set, before Nadal responded emphatically.

There were five breaks in a row in the second set, including the Spanish teenager going ahead 5-4 after a game lasting almost 20 minutes, converting his seventh break point, before serving out the set.

As the conditions settled, Nadal showed more aggression, coming into the net with regularity before taking the key break in the eighth game.

American 20th seed Fritz reached his first ATP Masters 1000 final with a 7-5 6-4 victory over seventh seed Andrey Rublev in one hour and 50 minutes.

The California native is the first American male to reach the Indian Wells since John Isner in 2012.

"It's just unreal, really. It doesn't even seem real. I'm just trying to take in the moment, regroup and come back tomorrow for the final," Fritz said in his on-court interview. "But it's a dream come true."

"Today I definitely played my best match of the tournament so far. I was so much more aggressive from the ground and so much more solid [with] my ground strokes, whereas [in] other matches I was maybe playing a bit safer.

"I really tried to take it to him and impose my game today. I did it well, so that helped a lot."

Iga Swiatek defeated Simona Halep 7-6 (8-6) 6-4 at the Indian Wells Open on Friday, progressing to the final and extending her winning streak to 10.

The Polish world number four came back from a break down in each set - as well as saving two set points in the first-set tiebreak - to level her head-to-head record with Halep at 2-2.

After taking out the WTA 1000 tournament in Doha last month, Swiatek has not had it all her way this week in California. Aside from a 6-1 6-0 trouncing of Madison Keys, the 20-year-old had to fight from a set down in her opening three matches.

Following a tight first set, Halep won three games in a row to take a 4-2 lead, but it was here Swiatek started to open up on return of serve.

She was ultimately able to capitalise on Halep's second serve, winning 14 of a total 21 points when given a second look, to earn five service breaks for the match.

Swiatek is now at least guaranteed to reach a career-high world number three ranking with, and a win in the final would move her to number two, only behind Ashleigh Barty.

She will meet Maria Sakkari in the final on Sunday, who broke down in tears after her hectic 6-2 4-6 6-1 win over Paula Badosa in the late match.

Despite Badosa having a higher first-serve rate than her opponent in the first set at 53.9 per cent, Sakkari was all over the second serve, winning nine out of a total 12 points.

After powering through the first set with flat hitting, the Greek world number six lost momentum in the second and forced play with rushed shot selection after getting broken early.

She still managed one of the shots of the match in trying to save that break of serve, scrambling across court to hit an underarm pass down the line.

Badosa kept her composure on serve to take the second set, winning 21 out of 29 points at an improved 72.9 per cent. Sakkari regrouped and exhibited her unique court coverage, however, taking the win after getting an early break.

Sakkari immediately broke down in tears afterwards, upon making her first WTA 1000 final and defeating the defending champion at Indian Wells.

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.

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."

Two top-ten talents have booked a date in the Indian Wells Open semi-final after Maria Sakkari and Paula Badosa won their quarter-finals in straight sets. 

First up, world number six Sakkari took on Ukrainian Elena Rybakina, prevailing 7-5 6-4.

Rybakina won the first three games of the match, working her way to an early 4-1 lead, before her Greek opponent rattled off six of the next seven games to claim the first set.

Sakkari again faced adversity early in the second set, coming back from 40-0 down in the second game to hold serve, before breaking the very next game to pinch the match-winning lead.
