Novak Djokovic has said he cannot currently enter the United States, putting his participation in next month's Indian Wells Masters in doubt.

Djokovic won his first match back on the ATP Tour since missing the Australian Open on Monday, beating Lorenzo Musetti in the round of 32 at the Dubai Tennis Championships.

The men's world number one had not played a competitive match since early December and was last month deported from Australia on the eve of the Australian Open.

That decision was a result of Djokovic opting not to join the majority of his tennis peers in getting vaccinated against COVID-19 and amid controversy over how he handled getting the virus himself in December.

He showed no signs of rust as he eased to a 6-3 6-3 win over Musetti in just 74 minutes in his first match of 2022, hitting five aces, winning an impressive 71 per cent of his second serves (17 out of 24) and saving all seven break points he faced against his Italian opponent.

However, at a press conference following his victory, Djokovic admitted he is currently unable to enter the United States, and is therefore on course to miss March's prestigious Indian Wells Masters tournament.

"As of today, not. I can't go, I can't enter the United States," he said.

"As of today I'm not able to play. But let's see what happens. I mean, maybe things change in the next few weeks."

Djokovic has been included on the entry list for Indian Wells despite the tournament requiring all players are vaccinated against COVID-19.

Images of Djokovic do not appear in any of the tournament's build-up social media posts nor on the website's promotional announcement, while his entry-list inclusion was little more than a footnote – though did include him.

The statement read: "A power-packed line-up of ATP top-10 players will join [Rafael] Nadal in looking to put together a breakthrough performance in Tennis paradise.

"2021 US Open champion and 2022 Australian Open finalist Daniil Medvedev (world no. 2), 2021 ATP Finals winner Alexander Zverev (world no. 3), and 2021 French Open finalist Stefanos Tsitsipas (world no. 4) will each be in search of their maiden title in the desert.

"Reigning BNP Paribas Open champion Cameron Norrie (world no. 13) will look to replicate his extraordinary 2021 title run, in which he won his first Masters 1000 crown.

"World no. 1 and five-time Indian Wells champion Novak Djokovic is also on the tournament entry list."

"All in all, it's a straight-sets win, so of course I have to be satisfied with my tennis, especially after not playing for two-and-a-half, three months," Djokovic said on court after the win.

"Of course, there were moments when I played great, there were moments when I made a couple of unforced errors in a row uncharacteristically. But it's normal to expect that [in my] first match after a while."

Djokovic will play the winner of Karen Khachanov against Alex de Minaur in the last 16.

Andy Murray is also through after a 6-7 (4-7) 6-3 7-5 win against Australian qualifier Christopher O'Connell. The Scot edged a tough match that lasted almost three hours, saving seven of eight break points faced. He will play either Alejandro Davidovich Fokina or Jannik Sinner next.

Elsewhere, Jiri Vesely overcame Marin Cilic 6-4 7-6 (7-3), while Filip Krajinovic beat Malek Jaziri 6-7 (4-7) 6-2 6-4 and Taro Daniel eliminated David Goffin after a 6-3 7-6 (7-5) win.

Novak Djokovic says he will play at whatever tournament will have him as he gears up to make his return to the ATP Tour.

The men's world number one has not played a competitive match since early December and was last month deported from Australia on the eve of the Australian Open.

That decision was a result of Djokovic opting not to join the majority of his tennis peers in getting vaccinated against COVID-19 and amid controversy over how he handled getting the virus himself in December.

Speaking to the BBC in a recent interview, Djokovic stated he was prioritising his right to choose what to put into his body above his sporting ambitions and confirmed he is willing to miss further grand slams if necessary.

With COVID restrictions still in place in many countries, Djokovic acknowledges his options to play are limited.

"I just have to follow the rules. You know, whatever tournament that I'm able to play, I will be trying to get to that country and play the tournament," Djokovic said ahead of facing Lorenzo Musetti in round one of the Dubai Tennis Championships.

"Obviously, I'm not intending to play the full schedule and that wasn't also my intention, as you brought it up and my goal prior to this season or the season before, and I was trying to aim to play my best at the grand slams and some of the 1000 events we have, of course, and playing for my country, those were the biggest motivations that I had in terms of the scheduling. 

"Right now, the situation is obviously different for me. So, I really can't choose right now. It's really about where I can go and play. So, wherever I have an opportunity, I'll be using probably that opportunity and going to play because this is what I do, it's what I love to do still. 

"And I have support from my family and my team is still there with me and that's what's important for me because obviously it was not easy for anyone in my surroundings to go through these kinds of circumstances and situations that we have been through.

"But it's very exciting to have everyone together here with me. And in Dubai, we're back on the tour and then we'll play this tournament and we'll see how it goes further down the line."

Several stars backed the decision for Djokovic to be barred from playing in Melbourne, with most noting that he had not followed the rules in order to do so.

But the Serbian says he has been received warmly ahead of his return to the ATP Tour.

"I haven't seen too many players, but the players that I've seen have been positive and welcoming," he added.

"And it's nice to see obviously. I can't say that was the case in Australia. It was a little bit strange, but here it's well so far."

Jelena Ostapenko secured the fifth WTA title of her career with a dominant victory against Veronika Kudermetova in the final of the Dubai Duty Free Tennis Championships on Saturday.

Ostapenko eased to a 6-0 6-4 win in just 65 minutes, which is expected to take her up to number 13 in the rankings, the first time the former world number five will have been in the top 20 since October 2018.

An impressive week for the Latvian has seen her beat Sofia Kenin, Iga Swiatek, Petra Kvitova, and Simona Halep on her way to the final, and she never looked like slipping up here.

It was consistency that made the difference, with Ostapenko winning 63.6 per cent of points on her first serve, but also an impressive 58.3 per cent on her second.

She took the first set in just 23 minutes, with her serve allowing her to zip through games with ease as Kudermetova had no answer to it, or indeed her returns.

The Russian recovered well in the second set and earned an early break, but things soon swung back to take Ostapenko to 5-3 and serving for the title. Kudermetova managed to break, only for her opponent to do the same to seal the win.

Jelena Ostapenko will meet Veronika Kudermetova in the Dubai Tennis Championships final after defeating Simona Halep 2-6 7-6 (7-0) 6-0 on Friday.

Ostapenko, who is the world number 21, stunned Halep in their first meeting in the 2017 Roland Garros final to win her first Grand Slam before the Romanian exacted revenge in Beijing later that season.

In their first meeting since that last-four clash, Halep raced out the blocks to wrap the first set in just 27 minutes as she converted both break-point opportunities to take an early lead.

However, Ostapenko responded emphatically in the following set, claiming a 3-0 advantage before eventually levelling things up after a one-sided tie-break separated the pair in the second.

Ostapenko carried her momentum in the deciding set as she made a blistering start, with Halep unable to win a single game as the 24-year-old secured victory in an hour and 36 minutes.

Kudermetova awaits the Latvian in the final after Marketa Vondrousova was forced to withdraw from her last-four match due to a right adductor injury.

The pair have not met before on the WTA Tour but boast identical records at the start of the 2022 season, with both winning eight of their matches and losing three.

Two-time champion Simona Halep strode through to the Dubai Tennis Championships semi-finals with a 6-4 6-3 win over eighth seed Ons Jabeur on Thursday.

A series of upsets meant Jabeur was the only seed left in the tournament going into Thursday, but she was outfought by Halep, whose win-loss record in 2022 now stands at 11-1.

The result followed two years on from Halep beating Jabeur in the second round at the same tournament, on that occasion needing a third-set tie-break to get the better of the Tunisia. Halep went on to win the title on that occasion.

"It was a very tough match. Even if it's in two sets, it felt much harder than that," Halep said of Thursday's win.

"I had in my mind big time the match from 2020, it was so close and I knew I'd have to fight till the end."

Quoted on the WTA website, former Wimbledon and French Open winner Halep added: "I've been focused on what I have to do, and I wanted just to push Jabeur back because she has such a big game."

Halep will face Jelena Ostapenko in the last four after the big-hitting Latvian overcame Petra Kvitova 5-7 7-5 7-6 (11-9).

Kvitova led by a set and a break, and twice served for the match, yet Ostapenko prevailed to add the 2013 Dubai champion to the scalps of Sofia Kenin and Iga Swiatek this week.

Ostapenko, who triumphed in two hours and 39 minutes, has now reached at least the semi-finals in four of her last seven tournaments.

The other semi-final will be contested by Veronika Kudermetova and Marketa Vondrousova.

Kudermetova reached her third career WTA 500 semi-final after beating lucky loser Jil Teichmann 6-2 5-7 6-4 in two hours and 23 minutes.

Vondrousova, meanwhile, became just the third ever qualifier to reach the last four of the tournament thanks to a 7-5 6-4 win over Dayana Yastremska.

Defending champion Garbine Muguruza, 2021 finalist Barbora Krejcikova and top seed Aryna Sabalenka were all eliminated from the Dubai Tennis Championships on Wednesday.

A day of upsets left Ons Jabeur, the eighth seed, as the top remaining player in the draw.

Some big names helped deliver the shocks, though, with world number two Sabalenka usurped by two-time Wimbledon champion and 2013 Dubai winner Petra Kvitova in straight sets.

Muguruza did not look like being one of the scalps as her title defence continued against Veronika Kudermetova.

But after taking the first set, the reigning WTA Tour Finals champion went down 3-6 6-4 6-4.

French Open champion Krejcikova, beaten by Muguruza in the final last year, also exited the tournament at the hands of Dayana Yastremska 6-3 7-6 (7-3).

Iga Swiatek let a set lead slip to Jelena Ostapenko, while two-time Dubai champion Elina Svitolina collapsed to lucky loser Jil Teichmann 7-6 (7-0) 6-2.

Jabeur, a winner against Jessica Pegula, was the only seed to win in a ruthless round of 16.

However, her reward in a still stacked quarter-final draw is a meeting with Simona Halep, another who has twice won in Dubai.

Top seed Aryna Sabalenka and defending champion Garbine Muguruza came through their first-round matches unscathed at the Dubai Tennis Championships on Tuesday.

Belarusian Sabalenka made light work of 19-year-old Marta Kostyuk, sealing a 6-4 6-1 win in one hour and 15 minutes.

Standing in her way of a third consecutive quarter-final in Dubai is Petra Kvitova, who beat Camila Giorgi on Monday.

Last year's champion and fourth seed Muguruza began her title defence with a 7-6 (7-5) 2-6 6-2 win over Czech qualifier Katerina Siniakova in two hours and 24 minutes.

Spaniard Muguruza will face Veronika Kudermetova in the second round after the Russian beat former world number one Victoria Azarenka in straight sets earlier on Tuesday.

There were also wins for eighth seed Ons Jabeur and 10th seed Elina Svitolina against Vera Zvonareva and Mayar Sherif respectively.

Elsewhere, there was a shock as qualifier Elena-Gabriela Ruse dumped out third seed Paula Badosa 6-3 5-7 6-4.

Ninth seed Danielle Collins is also out after the American retired due to dizziness in the second set against Marketa Vondrousova.

Sofia Kenin failed to put up a fight as she went down 6-1 6-2 to Jelena Ostapenko.

Iga Swiatek, Simona Halep and Barbora Krejcikova had little difficulty progressing to the second round of the Dubai Duty Free Tennis Championships on Monday. 

The unseeded Halep, who was champion in 2020, needed just an hour and 11 minutes to see off Alison Riske 6-2 6-4 as she looks to climb back up the rankings. 

The two-time grand slam winner went into this week ranked 23rd in the world after a difficult 2021 that was ravaged by injury, but she was in fine form against Riske. She showed good spirit to dig herself out of a hole in the second set and save two break points – the American's only ones in the entire match – in the fourth game. 

Swiatek, seeded sixth, was even more comfortable against Daria Kasatkina, defeating the Russian 6-1 6-2 in just 65 minutes. 

Kasatkina had no answer to Swiatek in the first set and, by the time she started to gain some form of momentum, she was already a set and a break down. 

Swiatek had few issues closing out the match and was joined in the second round by Petra Kvitova, who dropped just two games en route to an emphatic 6-2 6-0 defeat of Camila Giorgi. 

Krejcikova was the highest seed in action. The Czech, who lost to Garbine Muguruza in last year's final, was given a tougher examination than some of her rivals, with wildcard Caroline Garcia putting up a solid fight. 

Krejcikova came through 6-4 7-6 (7-0) in the end, blowing the Frenchwoman away in the second-set tie-break, though she will surely have to sharpen up if she is to go one better than 2021 – the 26-year-old hit just 12 winners to 28 unforced errors. 

There was also a victory for Jessica Pegula in an all-American affair with Coco Gauff that included 10 breaks of serve – the former won 6-4 6-4. 

Novak Djokovic has been included on the entry list for next month's Indian Wells Open despite the tournament requiring all players are vaccinated against COVID-19.

Last month, the world number one and 20-time grand slam winner was deported from Australia on the eve of the Australian Open after his entry visa to the country was cancelled due to him not being vaccinated against coronavirus.

Djokovic believed he was still eligible to enter the country and compete after testing positive for coronavirus in December and making a full recovery.

The Serbian was subsequently sent home as he lost the legal battle that dominated much of the sports news agenda during the early weeks of 2022.

Djokovic is set to make his return to the court at the Dubai Duty Free Tennis Championships later this month, with vaccination not a requirement.

But it is at Indian Wells, where the five-time champion has been announced as a competitor, prompting curiosity about whether more legal battles await or if Djokovic has since been jabbed.

An Indian Wells statement read: "With health and safety as the tournament's top priority, the BNP Paribas Open will require valid proof of full vaccination to enter the Indian Wells Tennis Garden for the tournament.

"For the second consecutive year, the BNP Paribas Open has partnered with CLEAR, the secure identity company, to facilitate the implementation of the venue's mandatory vaccination policy ahead of the 2022 tournament.

"The guidelines for the players are governed by the protocols established by their respective governing bodies, the WTA and ATP, as well as any restrictions established by the United States of America in regard to the vaccination status of international travellers entering the country."

Images of Djokovic do not appear any of the tournament's build-up social media posts nor the website's promotional announcement, while his entry-list inclusion is little more than a footnote – but, crucially, it does include him.

The statement continued: "A power-packed line-up of ATP top-10 players will join [Rafael] Nadal in looking to put together a breakthrough performance in Tennis paradise.

"2021 US Open champion and 2022 Australian Open finalist Daniil Medvedev (world no. 2), 2021 ATP Finals winner Alexander Zverev (world no. 3), and 2021 French Open finalist Stefanos Tsitsipas (world no. 4) will each be in search of their maiden title in the desert.

"Reigning BNP Paribas Open champion Cameron Norrie (world no. 13) will look to replicate his extraordinary 2021 title run, in which he won his first Masters 1000 crown.

"World no. 1 and five-time Indian Wells champion Novak Djokovic is also on the tournament entry list."

Novak Djokovic looks set to return to tennis at the Dubai Duty Free Tennis Championships in February.

The 20-time grand slam winner was deported from Australia on the eve of the Australian Open after his entry visa to the country was cancelled.

Djokovic, who told officials he was not vaccinated against COVID-19, believed he was still eligible to enter the country and compete after testing positive for coronavirus last month and making a full recovery.

Dubai does not have the same conditions for entry as Australia, and Djokovic will be free to compete at the tournament he has won five times previously provided that he can produce a negative PCR test result on arrival.

His place in the field was confirmed by tournament organisers on Thursday, with Djokovic joined by defending champion Aslan Karatsev and last year's beaten semi-finalists Andrey Rublev and Denis Shapovalov. The tournament runs from February 21 to 26.

After strong Australian Open campaigns, Felix Auger-Aliassime, Jannik Sinner and Gael Monfils have also entered the Dubai event, which will be staged for a 30th time.

Djokovic won a hat-trick of Dubai titles from 2009 to 2011, adding further triumphs in 2013 and 2020. Only Roger Federer, with eight titles, has had more success at the tournament.

Serbian superstar Djokovic is not entered for the ATP 500 events in Rotterdam or Rio de Janeiro that precede the Dubai tournament.

Unlike in Australia, the 34-year-old can likely expect the red-carpet treatment in Dubai, where Colm McLoughlin, CEO of tournament sponsors Dubai Duty Free, said: "We are delighted to see Novak back in Dubai for the 12th time when he will be seeking his sixth title and we wish him the best of luck."

Aslan Karatsev captured the first ATP Tour title of his career as the late-blossoming Russian triumphed in the final of the Dubai Tennis Championships.

At the age of 27, and with little warning, Karatsev has hurtled from obscurity before tennis went into lockdown 12 months ago to real prominence.

A 6-3 6-2 victory over South African Lloyd Harris on Saturday gave him a trophy for his efforts and he will enter the top 30 on Monday, having never had a double-digit ranking before this season.

Karatsev reached the Australian Open semi-finals last month, having had to win three qualifying rounds to make the main draw, and it took Novak Djokovic to stop that charge in Melbourne.

Now Vladikavkaz-born Karatsev is back in another winning routine, with Andrey Rublev, Jannik Sinner and Dan Evans having figured among his victims en route to the Dubai final.

The first-time champion said on Amazon Prime: "I am super happy. It was a tight match. [I was] really nervous. I want to congratulate my opponent for the final [run]. He did a great week. Every final is different, so I am happy that I won."

Karatsev had some promising results at Challenger Tour level last year but had never shown form on the main circuit until the start of 2021, and suddenly he looks a major force to be reckoned with.

He said of the rush of success: "You never know when it is coming. I did a good job with my team, with my coach and it has happened now."

Andrey Rublev's ATP 500 winning streak came to an end at the hands of Aslan Karatsev on a history-making day at the Dubai Tennis Championships.

Rublev had won 23 consecutive matches at this level, second only to Roger Federer (28), but Karatsev finally ended the Russian's remarkable run to progress to his first ATP singles final.

Karatsev, who incredibly went from qualifying to the semi-finals of the Australian Open this year, defeated his compatriot 6-2 4-6 6-4.

He became the first Wild Card to reach the final since Thomas Muster in 1997, doing so by hitting 41 winners and forcing 16 break points – of which he won four – during two hours and 12 minutes on court.

"It was a really tight match [against a] tough opponent," Karatsev said in his on-court interview.

"It was an unbelievable performance [from Andrey]. He didn't lose a match at an ATP 500 in [one year]. Everything was decided in one or two points, I feel happy."

The championship match will be between two first-time Dubai finalists after Lloyd Harris stunned Denis Shapovalov in the other semi-final.

World number 81 Harris, who overcame top seed Dominic Thiem, 14th seed Filip Krajinovic and former US Open finalist Kei Nishikori to reach the last four, came from a set and 4-2 down to defeat world number 12 Shapovalov.

He prevailed 6-7 (5-7) 6-4 7-6 (8-6) to reach a maiden ATP 500 final and become the first qualifier to reach the showpiece in Dubai.

"I don't have many words right now. I am super happy with that win," Harris said on court afterwards.

"Being a set and 2-4 down is mentally and physically a little bit troublesome for me, but I found my best tennis from there. I am just extremely happy with the result right now."

Denis Shapovalov secured a straight-sets win over Jeremy Chardy to set up a semi-final showdown with qualifier Lloyd Harris at the Dubai Tennis Championships. 

The third seed struck 26 winners en route to a 7-5 6-4 triumph on Thursday, but it was his serve that pleased him most.

Shapovalov, ranked 12th in the world, sent down 10 aces as Frenchman Chardy was deprived of any break-point openings.

"I've focused on my serve a lot in the past couple of weeks," the Canadian said.

"I have worked on placing it and tried out different types of serves to have more variation. I hope I can continue that.

"I've also worked on my footwork and positioning during rallies. I am feeling the ball well on both sides. If I am moving well, everything goes into place."

Harris was a surprise winner over Kei Nishikori, sealing a 6-1 3-6 6-3 success to dump out the former world number four.

Second seed Andrey Rublev defeated Marton Fucsovics 7-5 6-2 and will now face fellow Russian Aslan Karatsev.

Wildcard Karatsev continued his run with a hard-fought victory over teenager Jannik Sinner, coming from a set down in a 6-7 (5-7) 6-3 6-2 win.

Jannik Sinner fought hard to earn an impressive victory that knocked fourth seed Roberto Bautista Agut out of the Dubai Tennis Championships. 

The 19-year-old rising star, who won the Great Ocean Road Open last month, prevailed in a match that remained in the balance until the end on Wednesday. 

Sinner won 6-4 3-6 7-5 to reach the quarter-finals, with Bautista Agut following top seed Dominic Thiem - who lost in the second round - out of the tournament. 

After hitting 16 aces, Sinner – the youngest player in the ATP Tour top 100 – will face surprise Australian Open semi-finalist Aslan Karatsev next. 

Second seed Andrey Rublev is through after a comfortable 6-3 6-1 win over Taylor Fritz. 

Rublev will face Marton Fucsovics, who ousted Serbian Dusan Lajovic in three sets, in the last eight. 

The Russian now has 22 consecutive wins at ATP 500 events, a run that has included four titles at that level. Only Roger Federer has ever recorded a longer streak, doing so with a run of 28 between 2014 and 2016.

"I am really happy that I can win in straight sets and quite confidently," Rublev said. 

"I know Taylor since [the] juniors and it is always tough to play against him, because he has a huge serve and he is playing really fast. 

"The first set was not even rallies because everything was serve, winner or serve, mistake, so everything was so fast. 

"In these conditions, it is tough to find the rhythm. You don't know what's going to happen and it's really not easy, but I'm happy that in the end I made it."

Third seed Denis Shapovalov is also through after a 6-4 6-3 win over Hubert Hurkacz, the Canadian booking a last-eight meeting with Jeremy Chardy. 

Kei Nishikori will play Lloyd Harris in the other quarter-final.
