Novak Djokovic has confirmed his professional partnership with long-time coach Marian Vajda has come to an end.
Djokovic revealed the pair agreed to part ways last year following the ATP Finals in Turin.
Vajda served as part of Djokovic's team for 15 years, playing a pivotal role in the 20-time grand slam champion's glittering career.
"Marian has been by my side during the most important and memorable moments in my career," Djokovic said in a post on his official website.
"Together we have achieved some incredible things and I am very grateful for his friendship and dedication over the last 15 years.
"While he might be leaving the professional team he will always be family and I can't thank him enough for all he has done."
Vajda said: "During my time with Novak, I have been lucky to watch him transform into the player he is today.
"I will look back on our time together with immense pride and am so very thankful for the success we have achieved.
"I remain his biggest support on and off the court and look forward to new challenges."
Vajda was joined on Djokovic's team by former Wimbledon champion Goran Ivanisevic in 2019. Ivanisevic will continue working with Djokovic as he bids to add to his tally of major triumphs.
Djokovic, who is unvaccinated against COVID-19, missed the 2022 Australian Open after having his visa cancelled on "health and good order grounds", leading to his deportation.
Rafael Nadal's triumph in Melbourne gave the Spaniard the outright record for grand slam triumphs with 21.
Djokovic made his 2022 debut in Dubai last month, losing in the quarter-finals to Jiri Vesely. On Monday, he was usurped as world number one by Daniil Medvedev.
The 2022 MLB season will not start on time after owners and players failed to reach an agreement on a new collective bargaining agreement.
A deadline of 17:00 eastern time on Tuesday had been set by management, yet no deal was stuck.
Commissioner Rob Manfred announced that the first two series of the season were cancelled as the players remain locked out in an ongoing and bitter labour dispute.
"I had hoped against hope I wouldn't have to have this press conference where I am going to cancel some regular-season games," Manfred said on Tuesday.
"We worked hard to avoid an outcome that's bad for our fans, bad for our players and bad for our clubs.”
The MLB Players' Association issued a statement less than an hour after Manfred spoke, saying that players and fans worldwide are "disgusted, but sadly not surprised."
"What Rob Manfred characterized as a 'defensive lockout' is, in fact, the culmination of a decades-long attempt by owners to break our Player fraternity," the statement said.
"As in the past, this effort will fail."
The sides did make some progress, however, negotiating for over 16 hours on Monday before management made its "best and final offer" on Tuesday, the ninth straight day of meetings.
The players' union rejected that offer, and the owners followed through on their threat to cancel games.
Only the first week of games have been officially cancelled, so MLB could salvage a 156-game season starting on April 8 if a deal is made in the coming days, but the two sides remain divided with no imminent resolution in sight.
The players have yet to accept any cancellation and could try to negotiate for the unlikely result of rescheduled games. Manfred explained that the league will not compensate players for any cancelled games.
Among the key monetary issues still being discussed are the scale of a Competitive Balance Tax, minimum salaries and bonus pool money for pre-arbitration players.
Player salaries have dropped four per cent since 2015, when Manfred became commissioner.
Manfred – along with players' union leader Tony Clark – are likely to receive the ire of fans as baseball will have a shortened season for the second time in three years. The 2020 campaign was shortened to 60 games due to the COVID-19 pandemic.
Players stand to lose $20.5million in salary for every day of the season that is cancelled.
Tyson Fury has claimed it is "100 per cent" certain that he will retire after his fight with Dillian Whyte in April, casting doubt over whether he will ever face Anthony Joshua.
Fury and Joshua's camps were supposedly close to reaching an agreement for a huge heavyweight bout this year, yet that deal failed to materalise.
Instead, Fury is taking on another of British boxing's big names in the form of Whyte, who he faces at Wembley Stadium on April 23, with the WBC belt on the line.
However, 33-year-old Fury says he has no intention of carrying on his career after facing Whyte, who did not attend the first media conference to preview the fight.
Fury said the fight would "100 per cent" be the last of his career.
"I'm a two-time undisputed world champion," he added.
"This is the final fight of my career, I'm retiring after this, $150million in the bank, nothing to prove to anybody, healthy, young, I'm gonna buy a massive yacht abroad.
"I'm retiring, I'm out, this is my final fight, I'm done."
Fury has won 31 of his 32 professional fights, with the other being a contentious tie in his first of three meetings with Deontay Wilder – he triumphed in the second and third bouts.
Russian drivers have avoided being banned by motorsport's world governing body, meaning Haas driver Nikita Mazepin can compete for his Formula One team.
A range of measures was announced by the FIA on Tuesday, with teams representing Russia and close ally Belarus being suspended until further notice.
The conflict since the Russian-led invasion of Ukraine was addressed at an extraordinary meeting of the World Motor Sport Council (WMSC).
Drivers from Russia and Belarus will be barred from racing as representatives of their countries, but they will be allowed to compete as neutrals, providing they do not step out of line.
Mazepin is the only Russian driver on the F1 grid, with the 22-year-old due to start his second season in Bahrain later this month.
FIA president Mohammed Ben Sulayem told the meeting the FIA was observing events in Ukraine "with sadness and shock", adding that he hoped for "a swift and peaceful resolution". He also spoke of concern for the FIA's Ukrainian members and their current "intolerable hardship".
"We condemn the Russian invasion of Ukraine and our thoughts are with all those suffering as a result of the events in Ukraine," he added.
The FIA said none of its competitions should take place in Russia or Belarus until further notice, with flags or symbols of either country also banned for now, along with anthems and national colours.
Outlining its position on drivers, the FIA stated: "Russian/Belarusian drivers, individual competitors and officials to participate in international/zone competitions only in their neutral capacity and under the 'FIA flag', subject to specific commitment and adherence to the FIA's principles of peace and political neutrality, until further notice."
The Russian Grand Prix, which was due to take place in September, has already been cancelled by F1 chiefs, with the FIA describing that as a decision taken "for reason of force majeure".
The Miami Heat have surged to the top of the Eastern Conference but will receive a stern test of their credentials on Wednesday when they visit the Milwaukee Bucks.
Miami went 9-1 in February to take a two-game lead atop the East, capping a stunning month by routing the Chicago Bulls 112-99 on Monday.
Milwaukee sit two games further back but will be out to prove it is they who are the team to beat as the Bucks aim to successfully defend the NBA title.
The Bucks will not be facing a full-strength Heat team, with Kyle Lowry out for personal reasons and Victor Oladipo absent with a right knee injury.
Being slightly undermanned has not proven an issue for the Heat of late, yet it may be different against the Bucks and their two-time MVP.
Giannis Antetokounmpo used the month of February to deliver a scarcely needed reminder of why he is arguably the finest basketball player on the planet.
However, having made the NBA Finals two seasons ago, the Heat have shown they can deliver against top-tier opposition.
The Bucks, though, have been a thorn in Miami's side, sweeping them in the first round en route to the title last season, and this encounter may provide an insight into whether the Heat, who have won two out of their meetings with Milwaukee this season, can cause the defending champions serious problems in the postseason.
PIVOTAL PERFORMERS
Miami Heat - Bam Adebayo
No player was more crucial to the Heat's scorching run in February than Adebayo. He led Miami with 22 points per game last month and was fifth in the league in average plus-minus with 12.6. Adebayo was tied 10th in steals per game (1.73) and defensive rebounds (8.2) and ended the month ninth in blocked shots per game (1.55), illustrating his substantial value on the defensive end.
Milwaukee Bucks - Giannis Antetokounmpo
The Bucks have depth that gives them an excellent chance of repeating as champions but, when it comes to games against the elite, all eyes must be on Antetokounmpo.
He took his game to another level in February, averaging 51.3 points/assists/rebounds per game. Only Luka Doncic (53.8) fared better last month.
KEY BATTLE - Can Heat keep possession?
Miami have thrived this season despite often being lackadaisical in possession.
The Heat's turnover rate of 13.5 per cent is the fourth-highest in the NBA and they are facing a Bucks team whose rate of 12.1 per cent is superior to the league average of 12.5.
In other words, if the Heat want to stay hot against one of their main rivals in the East, they must flip the script and take better care of the ball.
HEAD TO HEAD
The Bucks are looking to continue a recent run of dominance in home games with the Heat, having won the last three meetings in Milwaukee.
Russian and Belarusian players, including ATP world number one Daniil Medvedev, will still be able to compete on the Tours and at grand slams, but the International Tennis Federation (ITF) has suspended the countries' teams.
Russia's Medvedev was only crowned world number one for the first time on Monday, though that success came amid the backdrop of an ongoing conflict between his nation and Ukraine.
To widespread international condemnation, Russia invaded Ukraine on Thursday, with that conflict since escalating further. Belarus, meanwhile, was effectively used as a staging post for part of the invasion force, though Belarusian president Alexander Lukashenko has insisted the nation's military did not and will not play any part in any operation.
Governments and organisations around the world, including governing bodies within sport, have responded with strict sanctions against Russia and certain individuals with links to president Vladimir Putin.
On Tuesday, the governing bodies of tennis (the ITF, ATP, WTA and the four grand slam events) announced sanctions of their own.
While Medvedev and other Russian and Belarusian players, including Andrey Rublev and WTA world number three Aryna Sabalenka, will be allowed to play in tournaments on both the men's and women's Tours, and the four grand slams, they will have to compete under neutral banners, with the flags of each country banned.
However, the WTA and ATP combined event in Moscow, scheduled to take place in October, has been suspended.
Meanwhile, Russia and Belarus have had their memberships of the ITF revoked, while all ITF tournaments set to be held in those countries have been suspended indefinitely.
Russia hold both the Davis Cup and Billie Jean King Cup.
The immediate upshot of the decision is that Elina Svitolina, the Ukrainian who is top seed at the Monterrey Open, will play her first-round match against Anastasia Potapova on Monday.
Svitolina said earlier in the day that she would refuse to play against any Russian or Belarusian opponent unless all national emblems, flags and colours were removed.
However, prior to the joint announcement from tennis' governing bodies, Svitolina told ITV News: "There's been a lot of discussion.
"Today they will release a statement that they will remove the flags. So we are waiting just for the final confirmation about that. I will be playing tonight because my opponent is going to be under a neutral flag."
Svitolina has pledged to donate all of her prize money from upcoming tournaments to assist Ukraine's fight against Russia.
The statement from tennis' governing bodies read: "A deep sense of distress, shock and sadness has been felt across the entire tennis community following Russia's invasion of Ukraine in the past week.
"Our thoughts are with the people of Ukraine, and we commend the many tennis players who have spoken out and taken action against this unacceptable act of aggression. We echo their calls for the violence to end and peace to return.
"The safety of the tennis community is our most immediate collective priority. The focus of the WTA and ATP in particular in recent days has been on contacting current and former players, and other members of the tennis community from Ukraine and neighbouring countries, to check on their safety and offer any assistance."
Tyson Fury has promised he would go to war for England as he praised those attempting to defend Ukraine from Russia's invasion.
The British heavyweight vowed to follow the lead of the likes of brothers Wladimir and Vitali Klitschko and Oleksandr Usyk if his homeland issues a call to arms.
WBC champion Fury said he would be "first in line" if civilians were to be conscripted.
Vitali Klitschko is mayor of Kyiv, while his brother and fellow former world heavyweight champion Wladimir has joined a territorial defense brigade. Usyk, a reigning world heavyweight champion, has also signed up, as has fellow star boxer Vasiliy Lomachenko.
Fury said in a news conference on Tuesday: "Fantastic. I'll be the first one to join up if England get involved or America. I'll be first in line for the job.
"My dad will as well, me and all the boys will be signing up to defend. So that's what I've got to say.
"If you're from that country and living there, defend it. Love your woman and fight for your country, that's what I say."
Fury puts his WBC heavyweight belt on the line against Dillian Whyte at Wembley Stadium on April 23.
It remains to be seen when the likes of Usyk and Lomachenko become available to resume their sporting careers
Frank Warren, Fury's co-promoter, said: "Everybody should be absolutely pulling for Ukraine, standing up to the bully, standing up for democracy.
"Those four fighters, everybody should be behind them. It's magnificent what they're doing."
Top seed Camila Giorgi was beaten in three sets by Caroline Garcia at the Lyon Open on Tuesday.
Italian Giorgi battled to take the first set but was pegged back by the home favourite before her game collapsed in a 5-7 6-4 6-0 defeat.
Dominant on serve in the opening set, Giorgi failed to take either of two break points at 3-2 up in the second set. She then won only one point in three consecutive games to allow Garcia to level.
The world number 29 earned just two points on serve in a one-sided decider as Garcia set up a last-16 clash with another Italian, Martina Trevisan.
Earlier, Russian Vera Zvonareva was comfortably beaten by seventh seed Alison van Uytvanck, who could await Garcia in the quarter-finals.
Zhang Shuai beat Kristina Mladenovic 7-6 (7-3) 7-5 to secure a match with Arantxa Rus, who defeated Danka Kovinic for the loss of just two games.
The top-ranked remaining player in the draw, world number 30 Sorana Cirstea, sealed a round-of-16 showdown with Stefanie Voegele after a comfortable 6-3 6-1 defeat of Mariam Bolkvadze.
Dillian Whyte did not attend the first news conference ahead of his bout with Tyson Fury, who insisted he "will not fail" to prove his quality.
Fury puts his WBC heavyweight belt on the line against Whyte at Wembley Stadium on April 23.
Despite the magnitude of the all-British bout, however, Whyte snubbed the chance to face the media on Tuesday.
According to reports, Whyte chose to remain at his training camp in Portugal instead.
That gave Fury free rein to speak, and he took that opportunity before capping off his appearance by facing off against Whyte's poster, in lieu of the man himself.
"I'm looking to show the people and the boxing fraternity how good I really am," said Fury, who defeated Deontay Wilder in their trilogy fight last year.
"And what better opponent to do it against than against a guy who’s been calling for it for 352 years. He finally gets his shot, on the biggest stage, against the biggest champion, on the biggest night.
"I will not fail. I'll show you how great I really am.
"I beat men like him seven days a week and 62 times on a Sunday and I'm going to prove that to you come April 23."
Whyte, who has won 28 of his 30 professional fights, comes into the clash on the back of his TKO victory over Alexander Povetkin, who defeated "The Body Snatcher" in 2020.
But Fury suggested his opponent had shown weakness by failing to attend the media gathering.
"He has definitely shown a white flag today," Fury said. "All this social media stuff, 'I'm not promoting the fight, I'm not getting involved in mind games'. He's given me that much more confidence - it's unbelievable.
"He's terrified. He's definitely showing the white flag in my estimation of this fight.
"The way he's going on about it, saying he doesn't want to go face-to-face, of course he doesn't, because he'll see that fire in my eyes and he'll think, 'I'm getting smashed to bits'.
"That's what it is, it's fear, it's terror. It's all of the above and I don't blame him for not being here today."
Major League Baseball has extended a deadline for talks with the MLB Players Association, which had been set for Monday.
MLB warned last week the 2022 season would be shortened and players would not be compensated if there was no new collective bargaining agreement by the end of February.
However, as talks continued between the league and the union into Tuesday, there was still hope such an outcome could be avoided.
"We want to exhaust every possibility to get a deal done," a league spokesperson said, with Tuesday now seen as the key day in negotiations.
Reports claim MLB has made a move towards MLBPA's demands in terms of the luxury tax threshold, minimum salary and bonus pool without yet meeting them.
Plans for further talks on Tuesday would suggest there is room for further movement as the two sides seek an end to the lockout.
Dillian Whyte labelled Anthony Joshua the number one "bull***t guy" in response to comments his rival made about his upcoming WBC heavyweight title fight against Tyson Fury.
Fury puts his belt on the line against Whyte at Wembley Stadium on April 23, while Joshua is slated for a rematch against Oleksandr Usyk, who holds the WBA Super, WBO and IBF straps.
Speaking to IFL TV, Joshua said he was rooting for long-time rival Whyte when he dons the gloves against Fury in a huge domestic showdown.
"It's a good opponent [for Fury], it's a good [title] defence against Dillian Whyte," Joshua said.
"Dillian Whyte needs to come in, look at what Tyson Fury does and reacts to, and do the complete opposite. Maybe work the body, and be conditioned to go the distance.
"I'm rooting for Dillian, even though I hate him, and I want to smash him one of these days. Go on Dillian, I'm with you all the way."
Replying on his Instagram story, Whyte seemed to be affronted by Joshua's declaration of hatred.
"Why so bitter. Number 1 bulls*** guy. @anthonyjoshua what did I ever do to you man," Whyte posted, before adding good luck to Joshua in the bout against Usyk.
In a seeming bid to defuse any simmering tensions, Joshua replied on his own Instagram story: "Hate is a strong word I respect you champ. I Just want to fight you at some point."
Joshua defeated Whyte with a seventh-round knockout when the two met back in December 2015.
Ja Morant chalked up a first ever career 50-point game for the Memphis Grizzlies and was labelled a "beautiful player" and "special kid" by San Antonio Spurs coach Gregg Popovich.
It was the first time in Grizzlies franchise history a player had achieved the target, and his overall haul of 52 helped Memphis – who sit third in the Western conference – to a 118-105 triumph on Monday.
Morant's performance followed a previous career-best 46 against the Chicago Bulls on Saturday, as he went 22-for-30 from the field and drained each of his four three-point attempts.
Popovich, at the age of 73, has seen plenty of the NBA's best during his illustrious coaching career and he waxed lyrical about Morant's talents.
"He's a beautiful player," Popovich said.
"What else can you say about him? It's not just that he's athletic. Everybody says 'he’s athletic'. Somebody says 'he's a freak of nature' because he's so fast. But he makes decisions. He knows what is going on on the court.
"So, you combine that cerebral part of his game with his athleticism and you've got a special kid."
There was no shortage of highlights on the reel for Morant, including him dunking over the seven-footer Jakob Poeltl and landing a buzzer-beater for a 68-58 half-time lead after catching a huge launch forward from Steven Adams in mid-air.
He also executed a sensational three-pointer from near the logo, but for Morant it was clear what the highlight of the night was.
"It's got to be the 50 [points],"he said.
"I'm thankful for my teammates, my coaches. They believe in me and have all the confidence in the world that I’ll make the right plays."
De'Anthony Melton, who scored 15 points for the Grizzlies, said of Morant: "He's at the rim every night, but the way he put it together tonight, he was just in attack mode from the jump.
"He got whatever he wanted, and it looked easy out there. It was just special to be out there and watch that."
Of Morant's leap over Poeltl, Melton added: "That dunk was crazy. The way he rose, stared at him and dunked it."
US Open runner-up Leyla Fernandez cruised into the second round of the Monterrey Open after a straight-sets win over Anna Karolina Schmiedlova on Monday.
Monterrey Open defending champion Fernandez won 6-2 6-2 over the Slovakian, with the Canadian second seed dominant in all aspects as she triumphed in one hour and eight minutes.
In the longest match of the day, fourth seed Sara Sorribes Tormo needed more than three hours to edge Kamilla Rakhimova 7-5 6-7 (2-7) 6-1.
Fifth seed Camila Osorio defeated Magdalena Frech 6-3 7-6 (8-6), while Briton Heather Watson won 6-3 2-6 7-6 (7-4) over Jule Niemeier.
Harmony Tan, Marcela Zacarias, Viktoriya Tomova and Beatriz Haddad Maia were other winners on Monday.
All-Star Ja Morant scored a career-high 52 points including a massive dunk and a buzzer-beater as the Memphis Grizzlies won 118-105 over the San Antonio Spurs on Monday.
Morant's 52-point haul was the second highest of the NBA season, behind only Trae Young who scored 56 points for the Atlanta Hawks against the Portland Trail Blazers on January 3.
The 22-year-old guard went 22-of-30 from the field including four-of-four from beyond the arc. Morant also hit a ridiculous half-time buzzer-bester after Steve Adams' full-court pass, catching and shooting in one motion.
Earlier in the second quarter, Morant produced a monster one-handed dunk over Spurs center Jakob Poeltl.
Morant's half-century follows up his career-best 46 points against the Chicago Bulls on Saturday. It was also the first 50-point game in Grizzlies franchise history.
Bucks bounce back with Giannis starring
Reigning champions, the Milwaukee Bucks, had dropped four of their past five games but Giannis Antetokounmpo led the way as they bounced back with a 130-106 win over the Charlotte Hornets. Antetokounmpo scored 26 points with 16 rebounds, four blocks, two steals and six assists, with Bobby Portis adding 20 points and 10 rebounds.
The Miami Heat took some ground in the race for top seed in the Eastern Conference with a 112-99 victory over the Chicago Bulls, with Tyler Herro contributing 20 points, six rebounds and five assists off the bench. DeMar DeRozan's 10-game run of 30-point games was halted, managing only 18 for the Bulls.
D'Angelo Russell's good run of scoring continued with 25 points as the Minnesota Timberwolves boosted their playoffs hopes by beating the Cleveland Cavaliers 127-22, with Karl-Anthony Towns () draining a key late three-pointer.
Short-handed Nets blown away
The Brooklyn Nets slumped to their 14th loss from their past 17 games, going down miserably 133-97 to the Toronto Raptors at home. Scottie Barnes dominated with 28 points, 16 rebounds and five steals for Toronto while the Nets, missing Kyrie Irving who is ineligible to play home games and head coach Steve Nash in protocols, had few winners
Russia and Belarus have been suspended from all International Ice Hockey Federation (IIHF) competitions at both national and club levels.
The IIHF announced the sanctions on Monday following an extraordinary meeting of its Council in the wake of Russia's invasion of Ukraine.
Russian president Vladimir Putin ordered an invasion of Ukraine last Thursday, with neighbouring Belarus effectively used as a staging post for Russian military.
The suspension prohibits Russian and Belarusian national teams and clubs from "participation in every age category and in all IIHF competitions or events until further notice".
In addition, Russia has been stripped of hosting rights for the 2023 IIHF World Junior Championship.
A statement from the IIHF read in part: "These two actions have been initiated by the Council in order to enable the IIHF to ensure the safety of IIHF Championships and all participating players, officials, and fans.
"The IIHF Council has not left out the possibility of further actions impacting future events or other IIHF activities but hopes above all for a swift and peaceful resolution to the war."
"The IIHF is not a political entity and cannot influence the decisions being taken over the war in Ukraine," said IIHF President Luc Tardif.
"We nevertheless have a duty of care to all of our members and participants and must therefore do all we can to ensure that we are able to operate our events in a safe environment for all teams taking part in the IIHF World Championship program.
"We were incredibly shocked to see the images that have come out of Ukraine. I have been in close contact with members of the Ice Hockey Federation of Ukraine and we hope for all Ukrainians that this conflict can be resolved in a peaceful way and without the need for further violence."
Ben Simmons will not make his debut for the Brooklyn Nets this week, though Kevin Durant is getting closer to a return from injury.
Simmons has yet to play for the Nets since this month's blockbuster trade that ended his stand-off with the Philadelphia 76ers, with James Harden going in the other direction.
During his introductory media conference, Simmons had said he hoped to be ready to make his season debut against the Sixers in Philadelphia or March 10.
That prospect appears less and less likely after Nets head coach Steve Nash revealed Simmons, who has struggled with a back issue since the Nets upped his workload in practice, is not close to being ready to play.
Speaking ahead of the Nets' clash with the Toronto Raptors on Monday, Nash said: "Ben is still working through a number of things and reconditioning so he's not gonna play this week but we'll keep working on his timeline and hopefully he can progress.
There is better news on Durant as he looks to make his return from a left knee sprain. He will not play in either of the Nets' successive games with the Raptors but could feature against the Miami Heat on Thursday or the Boston Celtics on Sunday.
"Kevin's getting close, we're hopeful that he can play this week," added Nash. "He won't play tonight or tomorrow but hopeful I guess that [his return] would be Thursday or Sunday."
The Nets are 32-29, eight games back of the Eastern Conference-leading Heat having lost seven of their last 10 games.
FIA president Mohammed Ben Sulayem has called an extraordinary meeting of the World Motor Sport Council to discuss a response to Russia's invasion of Ukraine.
Ben Sulayem made the announcement on his social media page on Monday.
The council will meet on Tuesday "to discuss matters relating to the ongoing crisis in Ukraine", a Twitter post read.
The FIA was awarded full recognition status by the International Olympic Committee (IOC) in 2013. The IOC has recommended Russian and Belarusian athletes be suspended from all sports.
In Formula One, such a ban would impact Haas driver Nikita Mazepin, the only Russian driver on the grid for 2022.
The Russian Grand Prix has already been removed from the F1 calendar in the coming season.
Bryson DeChambeau described his battle with injury as "one of the hardest moments of my life" as he confirmed his withdrawal from the Arnold Palmer Invitational.
Hand and hip injuries that forced DeChambeau to withdraw from the Saudi International this month have kept the world number 12 out of action.
And he will not make his return at the prestigious PGA Tour event at Bay Hill this week, pointing to a desire not to risk re-injury by playing again before he is 100 per cent.
Setting his sights on The Players Championship at TPC Sawgrass next week, the 2020 U.S. Open champion said in a video posted on Twitter: "Man, it's a tough decision right now.
"I have a lot of work to do to get everything back into order for this week and I just feel like it's too short of time for me to get back to 100 per cent and playing at 100 per cent capacity.
"Right now, I'm like 90 per cent. I don't want to go out there and hurt myself even more, and not be 100 per cent ready for the rest of the season.
"I don't want to come back early and then have to take more time off.
"It's a hard decision I have to make right now, but I'm going to have to unfortunately not play this week.
"At this point in time, I've got to take another week off and I'm going to try and get back and play for The Players.
"Right now, I just can't risk going out there and having it reaggravate. This has been one of the hardest moments of my life.
"I'm not able to do much, yes although I can hit some golf balls, it's not comfortable or fully comfortable.
"It's a bit frustrating but I appreciate your support. I want to get back out there as soon as possible but it's just not ready yet."
DeChambeau won the Arnold Palmer Invitational last year by one stroke ahead of Lee Westwood. That is his only victory since his sole major title at the U.S. Open two years ago.
Josh Taylor said he would be open to a rematch with Jack Catterall but at welterweight only as the British Board of Boxing Control said it was investigating the scoring of their controversial fight.
Taylor retained his world super-lightweight titles after a points win over Catterall that caused huge consternation.
The judges determined that Taylor had triumphed 112-113, 114-111, 113-112, despite his opponent dominating the first five rounds.
Taylor was also knocked down in the eighth round by 28-year-old Catterall, who stormed out of Glasgow's OVO Hydro following the judges' decision.
Catterall's trainer Jamie Moore, who spoke in the boxer's absence, said: "It's difficult to put into words.
"You're talking about a kid who has worked all his life for that moment, who waited three years for that opportunity. He then performs like that and beats the champion in his own backyard – and gets absolutely robbed."
The BBBofC announced on Monday it was investigating the scoring and would "advise accordingly".
Taylor, who said he took time off with his family before watching back footage of the fight, praised Catterall but insisted he felt the decision was fair.
"First and foremost, I want to congratulate Jack Catterall on a great fight. He rose to the occasion and fought a valiant fight. However, I believe I won a very close fight," Taylor said on Instagram.
"Many fans believe Jack deserved the decision, and that's fine. We both went in there and fought our guts out for 12 rounds… but the personal attacks on myself and especially my family are disgusting and uncalled for.
"My days at 140 are numbered. My future is at welterweight. Jack Catterall deserves another title shot, and as soon as possible. I've never ducked a challenge in my career, and I'd be happy to fight Jack again, but it would have to be at welterweight. Jack is a great sportsman, a helluva fighter, and deserves every bit of the admiration he's been receiving.
"Fighting as the undisputed champion on Scottish soil was a dream come true, but I'm only getting started. I'll be back and better than ever, this time ready to conquer the welterweight division."
