Maria Sharapova revealed she had failed a drugs test on this day in 2016.

The former world number one and five-time grand slam champion shocked tennis by announcing she had tested positive for meldonium at the Australian Open.

Sharapova explained she had been taking the substance since 2006 for an irregular heartbeat and a history of diabetes in her family and claimed not to have realised the medicine had been added to the World Anti-Doping Agency’s banned list at the beginning of 2016.

Then aged 28, Russian Sharapova was provisionally suspended from March 12, with Nike halting its sponsorship until the investigation was complete.

In a press conference at a hotel in Los Angeles, Sharapova said: “For the past 10 years, I have been given a medicine called mildronate by my family doctor, and a few days ago, after I received the ITF letter, I found out that it also has another name of meldonium, which I did not know.

“I failed the test and I take full responsibility for it. I let my fans down, I let the sport down that I have been playing since the age of four and I love so deeply.

“I know with this I face consequences and I don’t want to end my career this way and I really hope I will be given another chance to play this game.”

Sharapova was initially banned for two years but this was reduced to 15 months on appeal.

The former Wimbledon champion returned to competitive tennis in April 2017 before retiring in February 2020.

Rafael Nadal says he has made the “tough” decision to withdraw from Indian Wells as he is not yet “ready to play at the highest level”.

The 22-time grand slam singles winner has been off the tour since suffering a muscle injury in Brisbane in January.

He was set to mark his return with a first-round match at the BNP Paribas Open against Canada’s Milos Raonic on Friday.

However in a post on social media, the 37-year-old Spaniard said he is not yet ready to compete.

“It is with great sadness that I have to withdraw from this amazing tournament at Indian Wells,” he said.

“Everyone knows how much I love this place and how much I love to play here. That’s also one of the reasons why I came very early to the desert to practice and try to get ready.

“I have been working hard and practicing and you all know I took a test this weekend but I don’t find myself ready to play at the highest level at such an important event.

“It is not an easy decision, it’s a tough one as a matter of fact but I can’t lie to myself and lie to the thousands of fans.

“I will miss you all and I am sure the tournament will be a great success.”

Nadal has been replaced in the draw by India’s world number 101 Sumit Nagal.

Nadal made his comeback at the Brisbane International in January after spending a year on the sidelines due to a long-term hip problem.

The Spaniard sustained a muscle tear near his hip in his quarter-final defeat to Jordan Thompson in Brisbane, but scans revealed it was not in the same area.

Andy Murray produced an accomplished display to beat David Goffin in straight sets and progress to the second round of the BNP Paribas Open in Indian Wells.

Murray had won his previous seven meetings with the Belgian, but entered this clash in poor form and revealed last week it was likely he would end his decorated tennis career this summer.

The three-time grand-slam champion appeared rejuvenated following his announcement in Dubai and put in one of his best displays of the year to claim a routine 6-3 6-2 victory, which sets up a last-64 clash with Andrey Rublev.

In a nip-and-tuck first set, Murray had to be patient after a break point in Goffin’s opening service game was held before he was able to strike when 4-3 up.

Murray claimed his first break of the match in the eighth game and sent down two aces to seal a 34-minute opener where he won the final 10 points.

The momentum was with the British number four now and a double-fault by Goffin handed him an early advantage in the second set.

World number 61 Murray continued to ask questions of Goffin’s serve and a second break arrived to put him on the verge of a place in the last-64, which was sealed with an ace.

Compatriot Jack Draper suffered disappointment as he lost in three sets to Chris O’Connell in the first round of the BNP Paribas Open.

British prospect Draper had defeated Murray on his way to the last 16 of the tournament in 2023 but lost six games in a row in the final set to go down 1-6 6-3 6-2 to his Australian opponent.

It continued a frustrating period for Draper, who made the semi-finals of the Mexican Open last week but had to retire during his last-four clash with eventual champion Alex de Minaur.

Draper initially showed no ill-effects after he had battled food poisoning in Acapulco and eventually edged a lengthy fourth game to go 3-1 up before he saved a number of break points to consolidate his advantage.

Another break followed to allow the world number 37 to take the opener 6-1 but he sent down two double faults at the start of the second to hand O’Connell the initiative.

The Aussie did not look back and forced a decider, which started with Draper saving four break points before he broke to go 2-0 up.

Draper ran out of gas though, with world number 66 O’Connell booking a second-round meeting with Alexander Zverev.

Ronnie O’Sullivan vowed to pocket the golden ball next year after beating Luca Brecel in the final of the inaugural World Masters of Snooker.

O’Sullivan beat the world champion 5-2 in Saudi Arabia to win his fifth title of the campaign.

But his victory did not include potting the golden ball, which sits on the bottom cushion for as long as a maximum break is possible and is worth £395,000 if potted in addition to the 147.

John Higgins came the closest to getting a shot on the golden ball throughout the tournament in Riyadh, but having potted all 15 reds and blacks in the first frame of his second-round match against Mark Williams he ran out of position on the yellow.

O’Sullivan, who pocketed £250,000 by winning the tournament, is keen to achieve the feat at next year’s event.

“It’s been a fantastic tournament, a fantastic venue, the crowd have been amazing,” O’Sullivan told DAZN.

“It’s been a long time since we’ve been to the Middle East and to be back here is a treat.

“I’ll get the golden ball next year. I didn’t want to take it all at once.

“I’ll take the tournament this year and then the golden ball next year. It’ll be great.”

O’Sullivan had a break of 95 to take the opening frame but Brecel came back strong in the second to level.

The Belgian took a quickfire third frame with a break of 81 to edge into the lead but a missed black in the next allowed O’Sullivan to tie things up again with a 94 clearance.

And O’Sullivan raced to victory after the interval, with breaks of 121 and 124 securing a 79th professional title.

Runner-up Brecel said: “It’s been a fantastic few days. I’ve really enjoyed playing and I think the crowd has been fantastic.”

Katie Boulter was brought back down to earth with a straight-sets loss to Camila Giorgi in the first round of the BNP Paribas Open in Indian Wells.

Boulter arrived at the tournament riding a crest of a wave after she secured a maiden WTA 500 title at the San Diego Open to continue her excellent 2024.

It earned the British number one a new career-best ranking of 27, but her momentum was checked after a 6-3 6-2 loss in quick fashion to Italian opponent Giorgi.

Giorgi entered this match in poor form and early breaks were exchanged between the duo before the first set went the way of the 32-year-old in 40 minutes.

After Giorgi claimed a decisive second break to edge the opener 6-3, two early breaks handed her the initiative at the start of the next set.

Boulter did finally get off the mark to make it 4-1 but there was no way back and she exited after a 78-minute loss.

Tyson Fury has no concerns about his recent cut jeopardising the rearranged undisputed world heavyweight title fight with Oleksandr Usyk, but would be willing to fight with “blood everywhere” on May 18.

A proposed date of February 17 in Saudi Arabia had to be shelved after the British boxer suffered a “freak cut” above his right eye in sparring.

It forced the eagerly-anticipated contest to be postponed 15 days before all the heavyweight belts were set to be on the line, but Fury has dispelled fears of a repeat with an appearance in Riyadh ahead of Anthony Joshua fighting Francis Ngannou, who lost a split decision to Fury in October.

“It is healing good. I am not concerned. I never was concerned about the cut,” Fury told DAZN.

“From cut date to fight date was 15 weeks. A cut heals in about eight or nine weeks so I had plenty of time and if the cut opens in the fight, so f*** it!

“If it opens in the fight, there will be blood everywhere and so what? Don’t stop the fight. Let it continue because it’s an undisputed heavyweight championship fight. When I start camp at the end of March, I’ll be ready for sparring.”

A new date of May 18 was quickly rearranged to ensure the first undisputed world heavyweight bout of the century would still take place in 2024.

Fury hit back at his critics and insisted he would beat Usyk, who holds the WBA, IBF and WBO belts, before facing the winner of Joshua versus Ngannou.

“There are so many belts on the line and nothing competes with that,” WBC champion Fury said.

“This is the fight of the ages, nothing can compare with this. Not a show fight, not a crossover fight, not YouTube boxing, nothing. This is two undefeated world heavyweight championships colliding for all the belts and it hasn’t been done since whenever.

“Both guys fighting have beat everybody else so this is it. Whoever wins this fight is the best of this era regardless of what anyone’s opinion is or what anyone wants to say. Whoever wins out of me and Usyk is the best of this era.”

On Ngannou’s prospects against Joshua, Fury admitted: “I didn’t have a good night (in October). I had a lot of problems, but I am not here to make excuses.

“I can’t really gauge how good or bad he was because of how poor I was. Watching the fight, that’s what I am here for. The winner of these two will get a shot at a world title from me after I’ve beat Usyk twice this year.

“If Francis wins, it sets up a massive rematch for me and Francis, but if AJ wins, it sets up a big British fight for me and him.

“For me, I have got no money on either side of them so whoever wins it is a bonus because it’s a massive fight either way providing I get through Usyk twice.”

Lewis Hamilton believes that Max Verstappen is a serious contender to replace him at Mercedes next season.

A vacancy has opened up at the Silver Arrows following Hamilton’s shock decision to join Ferrari.

The apparent division at Red Bull – following the very public spat between team principal Christian Horner and Verstappen’s father, Jos – has led to speculation that the Dutch driver, despite being under contract until 2028, could quit the team which has carried him to the past three world championships.

“My move has shown that anything is possible,” said Hamilton ahead of this weekend’s Saudi Arabian Grand Prix. “I know and I am sure Max is on the list.”

Hamilton and Verstappen’s relationship soured in 2021 as they fought for the world title – with Verstappen taking the championship following a deeply contentious end to the season decider in Abu Dhabi. Tensions were also high between Mercedes and Red Bull.

But Hamilton continued: “I wouldn’t say I am surprised that he is being considered. He is a great driver.

“And Max in that moment did what he had to do. It was nothing on him. It was the sport that let us down and that wasn’t his fault. If I was in his position I would have done the same thing, so there are no issues there.

“If you run a team you want the best driver and a driver that brings in the eyeballs and brings in the sponsorship and he is one of those. I understand it but it wouldn’t make sense for him, but it will be interesting to see.

“George (Russell) is an integral part of this team and he will be here for the long haul. He is doing a great job and he will grow to be a leader of this team so it will be interesting to see what their relationship looks like but I am sure they will work it out.

“It will definitely be a strong line-up.”

Earlier, Russell said he would welcome the challenge of going up against Verstappen, who has won 18 of the last 19 races and is the overwhelming favourite to claim another victory in Jeddah on Saturday night.

“This is my third season alongside Lewis, the greatest of all time and I feel like I have done a pretty good job alongside him,” said Russell.

“So, whoever were to line up alongside me, I welcome the challenge.

“You want to go against the best. I believe I can beat anybody on the grid. Having Lewis as my benchmark has been a good benchmark for sure.

“Any team wants to have the best driver line-up possible and right now Max is the best driver on the grid.

“If any team had a chance to sign Max they would 100 per cent be taking it but the question is on his side and Red Bull’s side and we don’t know what is truly going on behind closed doors and it is none of our business. But it would be exciting.”

Sam Underhill is savouring his England revival having feared his international career might already be over.

Underhill is poised to win his 34th cap in Saturday’s Guinness Six Nations clash with Ireland at Twickenham after returning to favour under Steve Borthwick – a comeback he views as a personal triumph.

Still only 27, the big-hitting Bath flanker missed 20 successive Tests from the second match of the 2022 tour to Australia because of a combination of concussion and selection.

But a sliding doors moment arrived when Jack Willis sustained a neck injury in last autumn’s World Cup and Underhill was propelled straight into the back row for the bronze final against Argentina.

A defensive masterclass consisting of 24 tackles resulted in the man of the match award and now that he has played four consecutive Tests, he grants himself a moment of recognition.

“It’s been class. All I wanted to do was to get back into this team and, if I’m perfectly honest, I was doubtful that that would happen,” Underhill said.

“This is the first time I’ve done a full campaign with Steve, under him as a coach. I played in the Aussie tour and then didn’t I play again until the third-fourth play-off, which was 18 months.

“My aim personally was to get back here. Now that I am, as a player you’re constantly looking for challenges, or things to go wrong or not be going that well.

“Whereas actually now, I am where I want to be and while I want to keep on improving, I have taken a moment to say to myself, ‘hey, you’re doing it, well done’.

“I’m not just content to be here, I want to win with this team and help and perform as well as I can for them. It’s been class.”

Underhill’s standing among his team-mates was evident in July when Ben Earl spoke of the “shock” that rippled through the squad when the destructive openside was dropped early in the build-up to the World Cup.

As one of half of Eddie Jones’ ‘Kamikaze Kids’ who lit up Japan 2019, he was expected to travel to France having proven he can thrive on the greatest stage of all.

Instead, he was consigned to playing in the Premiership Rugby Cup for Bath in what was a test of his ability to rationalise the vagaries of selection.

“It would be remiss of me, and certainly any player, to think that they have to be in any team,” Underhill said.

“I respect the other players too much to say ‘I should be there’. A decision’s going to have to be made at some point, someone’s going to miss out.

“But someone missing out doesn’t mean they are a bad player. You’re not a better player for being picked than not being picked, or for getting a contract or not getting a contract. That’s the hard thing to get your head around sometimes.

“A lot of people talk about being process-driven but that’s easier said than done. When you aren’t picked, the ability to think that this isn’t actually a reflection of where I am, is important but tough.

“You’re allowed to be disappointed if you’re not selected, you’re allowed to be upset. What isn’t great for you is if you then let that affect your behaviour and let that affect your actions that come afterwards.”

Borthwick names his team to face Ireland at lunchtime on Thursday with England looking to bounce back after a comprehensive defeat to Scotland in round three.

A furious Kieran O’Neill was given the all-clear to resume riding on Wednesday, having been prevented from taking his rides at Southwell on Tuesday in an incident which has put the British Horseracing Authority’s trial of saliva and sweat testing in the spotlight.

O’Neill had three mounts booked at the Nottinghamshire track’s evening meeting, but was unable to take part after being stood down by the BHA following a failed saliva test.

And while a subsequent urine test returned a negative result, O’Neill – who swiftly took to social media to speak of his anger, saying he was “fuming” – was not permitted to ride before passing another test ahead of racing at Kempton and feels his reputation has been unfairly tarnished.

He told Sky Sports Racing: “I was the one to comment, to put my tweet out that I have done nothing wrong and have nothing to hide. I wanted to be the one when I got home to write a tweet and let everyone know. I have nothing to hide, I have not done anything wrong here and something needs to be done very quickly.

“It is very embarrassing for me to have to leave the racecourse yesterday and everyone is there looking at you. The first person I bumped into was Scott Dixon and I have to go and explain myself why I can’t ride for him.

“I was so embarrassed speaking to my partner on the phone last night, speaking to my mum, this has now happened and even when I’m cleared from this urine sample and things are back to normal, my name is still out there, I have failed this swab test twice yesterday.

“It’s something that for a young kid coming into the game of 17 or 18, he could fail a swab test and his career is over straight away before it starts.

“My urine test will come back clear, I have no doubts about that in my mind. I rarely drink, never mind take drugs. Everyone who knows me and knows my character knows I’m the first person to be anti-drugs.

“I really cannot see how this has happened. Is there something wrong with the salivas again? For me yes, because I have done nothing wrong, I have never taken a drug in my life and I am clear.”

A saliva test pilot was paused by the BHA in September 2022 after Sean Levey returned a false positive that saw him sidelined for eight days and miss out on a potential £20,000 bonus as leading rider during the Racing League.

O’Neill added: “Sean said if this doesn’t go then someone else is going to get done, but never in a million years did I think it would be me. Sean Levey got it right, it’s come back and it’s me. Have the BHA got it wrong again? I don’t know.

“But I agree with Sean Levey and for me something has gone amiss. I have no problem doing any test, they can take hair, another urine from me, that is no problem. I have been tested in France and probably 20 times last year and nothing has ever been found, but now all of a sudden since the swab tests have come back, something was found.”

Posting an update on X, he said: “Just been to Kempton to have another swab test after last night’s embarrassment. Given the all-clear as expected. Thankfully the current testing system has now been paused until they get to the bottom of this.”

Professional Jockeys Association chief executive Paul Struthers said the body was “unaware” a new trial had been introduced until Tuesday evening and immediately requested the procedure be put on hold pending further investigation.

He said: “We have been discussing with the BHA a pilot of trialling a new saliva and sweat testing kit since January, following the two previous trials of different testing kits. However, no dates for the pilot had been agreed and we were told what the protocol would be in the event of a non-negative test, which is very different to agreeing it.

“Issues that arose during the previous two pilot schemes meant that the PJA and its members had legitimate concerns about the testing kits and the process.

“At our last meeting with the BHA on February 23, we stressed these concerns and explained how important communications would be in advance of any pilot. What was agreed at that meeting was that the BHA would draft some initial communications materials which would be shared with the PJA for further comment.

“This never happened and we were therefore unaware until last night that the pilot had even commenced.

“Following events of last night, this morning we wrote to the BHA requesting an immediate suspension of the pilot scheme. The BHA has subsequently confirmed that no further testing with the swab and saliva kits will take place until the situation with Kieran O’Neill has been resolved and understood.

“This is a sensible decision in the best interests of fair regulation, a decision we obviously support and welcome. The rest of the testing regime will continue as normal.”

The BHA insists the procedure is sound, with rider safety “a priority” for racing’s regulator, and that the process for handling non-negative samples had been agreed with the PJA.

A statement said: “The process for handling non-negative samples on raceday as part of the ongoing pilot of sweat/saliva sampling was agreed between the BHA and PJA.

“As part of the agreed process, which utilises a Home Office-approved testing kit used by police forces globally, should a rider return a non-negative sample then they will be tested a second time.

“Should the second sample also return non-negative then, in the interests of safety for horses and riders, the jockey should be stood down for the day.

“Mr O’Neill was stood down on the day having provided two non-negative samples. Sixteen jockeys were tested yesterday and 16 on Monday with only Mr O’Neill returning these two non-negative samples.

“As part of the process a urine sample screening is also be taken on the day. This is for indicative processes only as part of the trial. It operates to different thresholds, and does not form part of the immediate regulatory process. Mr O’Neill’s urine sample returned a negative result on-course but is not relevant to his being able to ride today and beyond.

“This same urine sample is also sent away for analysis at the official testing laboratory. Mr O’Neill will be permitted to ride today and beyond, pending the return of this urine result, provided he returns a negative sweat/saliva sample prior to weighing out. A hair sample will also be taken.

“Ensuring the safety of jockeys competing in our sport is a priority for the BHA. We appreciate the strength of feeling from Mr O’Neill but this alone is not enough to make judgement about the testing process, or its ability to detect the intentional or sometimes inadvertent presence of substances in a rider’s system. The proper process must be allowed to take its course.”

Max Verstappen stood by his father Jos, saying “he is not a liar” following his explosive claim that Red Bull could explode if Christian Horner remains as team principal.

Speaking ahead of this weekend’s Saudi Arabian Grand Prix, Verstappen was asked if his father regretted his remarks, which not only cast further doubt over Horner’s future, but of his son.

“I have not asked him that but my dad, from how I know him in go-karting, is very outspoken and he is not a liar, that is for sure.

“My dad and I are very close. We call every day.”

Verstappen’s manager Raymond Vermeulen met with Horner earlier this week in an attempt to clear the air at the crisis-hit team. Neither Max, nor Jos, were present.

And Verstappen added: “I don’t see myself in F1 without them (his father and manager) by my side.”

British Horseracing Authority chief executive Julie Harrington will not be pushing the panic button just yet should Ireland once again dominate at next week’s Cheltenham Festival.

Following a nightmare Festival for the home side in 2021 which saw just five winners for British trainers, the BHA set up the Quality Jump Racing Review Group, with a stated aim “to strengthen the performance of British jump racing at the top end of the pyramid”.

A series of recommendations was then unveiled at the start of 2022, with further tweaks to the fixture list this term in an attempt to improve the upper tier of British National Hunt racing.

Harrington says it is too early to really see those initiatives come to fruition, but with Triumph Hurdle favourite Sir Gino the only British-trained ante-post Grade One market leader throughout next week, with Willie Mullins holding a tremendously strong hand on all four days, the issue remains a high-profile one.

She said: “We’re well aware of the number of Irish favourites across all the days. It is early days and there’s interventions all the way through breeding in terms of incentives for British-bred, retaining your horse here in training, but we’re not naive.

“We know the decision of many owners to place their horses with what they would consider in-form trainers. When you speak to the top British-based trainers, they do understand it is often cyclical which is why the fact it’s early days, you do need to let some of the interventions play out a bit more.

“Is it something we continue to be concerned about and continue to have a watching brief on? Of course. It’s been well debated some of the interventions or potential interventions that we’ve consulted on, but we will continue to do so.”

Talks are currently ongoing between the BHA and bookmakers on levy reform and Greg Swift, director of communications and corporate affairs, believes the issue of competitiveness is ultimately linked to the levy.

“It’s a valid point. It brings us back to the need for levy reform,” he said.

“One of the cases that we have made to DCMS throughout the entire process around the need for levy reform is around the competitive issue and making sure that we have enough money flowing into the sport to maintain Britain’s competitiveness and our position at the top table.

“That is one of the things we will continue to press.”

Wales boss Warren Gatland has sprung a major selection surprise by omitting established centres George North and Nick Tompkins from his line-up for Sunday’s Guinness Six Nations clash with France.

But Wales assistant coach Mike Forshaw says both players have “jumped back on the horse” after being left out, with a new midfield pairing of Joe Roberts and Owen Watkin preferred.

While North and Tompkins have 155 caps between them – North is Wales’ most experienced Six Nations squad member – 23-year-old Scarlets centre Roberts will make his first tournament start and Watkin is recalled after featuring against opening opponents Scotland.

“I think it is an opportunity to have a look at Joe,” Forshaw said. “I think Joe was unlucky not to go to the World Cup.

“We just felt if we were going to have a look, this was the game to do it. He (Roberts) is a really promising young 13 going forward, and Owen Watkin has a lot of experience.

“I suppose there is always a risk in every selection, but I suppose we have to be confident in the messages we are giving and the coaching we are doing.

“They (North and Tompkins) are not injured. Nick and George have been spoken to. They firmly believe in what we are doing.

“I don’t think they have been dropped. They have had two games together and they have done extremely well.

“But we have got to see Joe playing, and we are going to see him. We’ve decided to make that switch this week, and we’ve got to back him.”

Wales have lost their last four Six Nations games against France, but they tackle a struggling Les Bleus team defeated by Ireland and one that drew at home against Italy either side of narrowly beating Scotland.

Wales, though, have yet to win in this season’s competition ahead of their final two fixtures against France and Italy, which are both at the Principality Stadium.

Forshaw added: “The two boys were disappointed, but this morning they jumped back on the horse and they were very supportive of Owen and Joe. George is a great man around this environment, and he totally gets it.

“I would be disappointed if they weren’t disappointed. Selection day is always tough because you want to be in the team, you want to play for Wales.

“This morning they were both great. They were down yesterday, which I get because I have been there and know what it is like, but the two boys who have come in they will fully support them.

“It’s just finding out what the next World Cup cycle is going to look like in material and personnel. I think at the end of this tournament we will have a good idea who is going to Australia (on Wales’ summer tour) and then going into the autumn.”

Elsewhere, Wales captain Dafydd Jenkins has been switched from lock to blindside flanker, with Will Rowlands called up as Adam Beard’s second-row partner, while hooker Ryan Elias replaces Elliot Dee.

It will be Jenkins’ first appearance in the number six shirt for club or country, and he takes over from Alex Mann.

Rowlands missed Wales’ opening Six Nations appointment with Scotland after his partner gave birth, and he then featured off the bench in defeats to England and Ireland.

Mann is among the replacements, where his colleagues include fellow Cardiff forward Mackenzie Martin, 49 times-capped Dee and Scarlets scrum-half Gareth Davies.

“I don’t think it is a risk with Daf at six,” Forshaw said. “He is around two very smart back-rowers.

“Will Rowlands played 70 minutes on the weekend in Paris (for his club Racing 92). I saw glimpses of him getting back to his best. I think it is a good fit for us this week.”
