Bukayo Saka has withdrawn from the England squad for upcoming friendlies against Switzerland and Ivory Coast after testing positive for COVID-19.

Saka had been isolating from the rest of the squad at St. George's Park since Wednesday, but the decision has now been taken for the 20-year-old to return home.

Three Lions manager Gareth Southgate will not call up a replacement for the Arsenal forward.

Saka has made 33 appearances for the Gunners in all competitions this season, scoring 10 goals and registering five assists.

Southgate has already had to make several changes to the initial squad named, with Kyle Walker-Peters, Tyrick Mitchell, Ollie Watkins and Sam Johnstone all being drafted in to replace unavailable players.

Johnstone himself then also had to be replaced by Fraser Forster on Wednesday after withdrawing through illness.

England welcome Switzerland to Wembley on Saturday before also hosting Ivory Coast on Tuesday as preparations continue for the World Cup in Qatar later this year.

Kyrie Irving has been cleared to play home games for the Brooklyn Nets after changes to New York's vaccine mandate were officially announced on Thursday.

It means Irving will be eligible to take to the court when the Nets host the Charlotte Hornets at Barclays Center on Sunday.

New York City mayor Eric Adams recently removed restrictions requiring proof of COVID-19 vaccination to enter establishments including bars, restaurants and sports arenas, but the mandate for private sector employees remained in place.

As a result, Irving – who is unvaccinated – was only able to attend home games as a spectator.

However, at a media conference at Citi Field on Thursday, Adams confirmed the mandate for athletes and performers had been lifted.

"This is about putting New York athletes on a level playing field," he said. "We were treating our performers differently because they live and play in New York City."

Adams did reiterate his previous stance that athletes, including Irving, should reconsider their stance on vaccination.

"Kyrie, you should get vaccinated," he said. "This does not change my message that everyone should get vaccinated."

Irving, who has played just 20 games this season, scored 43 points in Brooklyn's 132-120 loss to the Memphis Grizzlies on Wednesday.

Simona Halep has withdrawn from the Miami Open after aggravating a thigh injury.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

Ravindra Jadeja knows he has "big boots" to fill after he replaced MS Dhoni as Chennai Super Kings captain.

It was the end of an era on Thursday as the defending champions announced that Dhoni had decided to relinquish the captaincy.

The former India captain has led CSK from the start of the IPL in 2008, guiding the franchise to four titles and losing five finals.

Dhoni lifted the trophy in Dubai last year after his side beat Kolkata Knight Riders by 27 runs in the final.

The 40-year-old wicketkeeper-batsman steps down just two days before the Super Kings start the defence of their title against KKR at the Wankhede Stadium.

India all-rounder Jadeja has been charged with the task of replacing Dhoni, who will continue to play for the franchise this season and beyond, and knows he will be a hard act to follow.

Jadeja said: "I'm feeling good. At the same time, I also need to fill in big boots, [Dhoni] has already set the big legacy so I need to carry [that] forward.

"I don't need to worry too much because he is here so whenever I have a question to ask, I'll definitely go to him.

"He'll be my go-to person. He was and still he is today, so I'm not worried too much."

Julian Weigl was taken aback by his recall to the Germany squad after a five-year absence, having previously been considered a potential future superstar.

Weigl rose to prominence at Borussia Dortmund, earning his first senior Germany cap 14 months after moving to BVB from 1860 Munich in 2015 as a 19-year-old.

His form during his first couple of seasons in the Bundesliga drew links with some of Europe's biggest clubs, with Paris Saint-Germain, Barcelona and Manchester City apparently particularly keen on the talented deep-lying playmaker.

But he struggled to maintain that level after Thomas Tuchel's exit and was frustrated by untimely injuries, ultimately falling out of favour and being sold to Benfica for a reported €20million in January 2020.

The move was indicative of the decline in Weigl's reputation and he was being linked with another move less than a year after joining Benfica due to early struggles with Jorge Jesus.

But this season he has become a key figure and played in seven of Benfica's eight matches en route to the Champions League quarter-finals, helping him back into the Germany setup.

"When the coach called me, I was with my team-mate Soualiho Meite. I couldn't believe that Hansi [Flick] had called me and that I'd missed it," he told reporters.

"I knew I had to call him back. I was absolutely thrilled, we chatted for a short while and then I immediately rang my parents and my wife. They were some emotional phone calls. My family and my wife were also over the moon.

"I was extremely pleased when I got the call from Hansi. I wasn't expecting it. When you're putting in good performances for your club, you do get your hopes up a little bit, but it still came as a surprise.

"I was looking forward to seeing the lads again, and so I arrive here with a really positive energy. I've always looked out for when the national squad gets announced, and I'm more than aware that you have to be performing at the top level at your club week-in, week-out to earn your selection.

"But I never once said to myself at any time that my performances deserved to be rewarded with a call-up – I simply tried to keep concentration on myself and my game. Because of that, the eventual call-up was even more of a pleasant surprise."

Despite the promise he showed early on at Dortmund, Weigl only ever featured five times for Germany.

His most recent outing was 66 minutes in a friendly with England way back in March 2017 – now 26, Weigl does not think his playing style has changed significantly, but leaving Germany helped him grow and he feels better physically.

"Generally speaking, I'm still the same player," he continued. "What's changed is that I've become more mature and more experienced – playing abroad has certainly helped me in this regard, as well as becoming a father.

"My daughter helps me to relax, as my life is so fast-paced. I've improved from a physical perspective, too."

Weigl's recall comes at a potentially critical moment as well. With the World Cup starting in less than eight months, the midfielder surely has a genuine opportunity of being in the selection that travels to Qatar.

He is now focused on proving to Flick that he is worthy of consideration.

"I'm trying to show off what I can do every day that I'm here, as well as take on board the ideas of the head coach and work them into my game," he said.

"I'm asking for the ball a lot in the sessions and I'm not afraid to do so, because that's how I'm going to prove to the head coach that I'm a serious option for the World Cup squad, because I can be relied upon at any time and that I can put in a solid performance when needed."

Germany, who have already qualified for the World Cup, will face Israel and the Netherlands in friendlies during this international window.

England's Six Nations performance has been labelled "incredibly disappointing" by Rugby Football Union chief executive Bill Sweeney.

Eddie Jones' side backed up a poor 2021 championship campaign with just two wins from five again, as their third-place finish lagged far behind France and Ireland.

A year-and-a-half out from the 2023 World Cup across the channel, England look unlikely to contend for the crown as they did in Japan in 2019.

"We are all, as an organisation, incredibly disappointed with what happened this year in the Six Nations," Sweeney told the media. "You'd expect more.

"To come away with fifth-place last year and two wins, and then going into this year's Six Nations feeling in good shape and expecting more, to only have a further two wins out of 2022 and come third was incredibly disappointing for us.

"We demand more in terms of our results and performances. Emotions have been running very high, it still feels quite raw. There is a great deal of frustration and disappointment."

Sweeney paid tribute to England supporters for their contributions, while stressing the team has still made progress under Jones in the last year.

"We saw a fantastic response from the fans during the Ireland game, one of the best examples of connecting with the team," he added.

"We understand why they're expecting more and feel not in a great place at the moment.

"We do feel there's been some real positive developments. We do feel we're on a path to the right direction. If you look at where we were 12 months ago: we're in a better place.

"It's a very tight-knit squad. There is a strong spirit. The players believe in [Jones] and believe he's taking them in the right direction.

"We're very excited by developments despite the fact we're coming out of a very difficult period. We know we're going to get better."

Naomi Osaka looked relaxed and composed as she eased to a straight-sets win at the Miami Open, and offered a clue as to why when speaking to reporters afterwards.

The 24-year-old revealed she has started seeing a therapist after her recent loss at Indian Wells, where she suggested a heckler had affected her performance.

Osaka was left in tears as she struggled to deal with someone apparently shouting "Naomi, you suck!" during her second-round defeat to Veronika Kudermetova.

She also withdrew from Roland Garros last year, citing mental health concerns.

However, the three-time grand slam champion produced a strong display in her first round encounter in South Florida to beat Astra Sharma 6-3 6-4 on Wednesday.

"I don't know if I'm allowed to say this, but I finally started talking to a therapist after Indian Wells. It only took like a year after French Open," she told reporters after her win.

"She kind of told me strategies and stuff. I realise how helpful it is. I'm glad that I have people around me that told me to, like, go in that direction.

"But, yeah, I was basically just remembering all the things that she told me to do, just to take deep breaths and reset myself when I need to."

The world number 77 revealed it was partly her sister, former professional player Mari Osaka, showing concern that led her to seek out therapy.

"I feel like I've been trying a lot of different things because I tend to internalize things, and I also want to do everything by myself," Osaka clarified, adding that her coach, Wim Fissette, had also encouraged her to do so.

Osaka believes she is now better prepared to handle a similar situation to Indian Wells should it arise, having realised it may have been the first time she has been heckled during a game.

"I think for me, the situation in Indian Wells, I've kind of thought back on it. I realise I've never been heckled. I've been booed, but not like a direct yell-out kind of thing. It kind of took me out of my element.

"I feel like I'm prepared for it now. I was kind of bracing myself before the match to just know that's a thing that could happen now. I think I just needed to change my mindset a little."

It all comes down to this. After 14 days of Test cricket that has yet to produce a match-winner, Pakistan's home series against Australia will be decided on the final day in Lahore, and it could hardly be any more tantalisingly poised.

Australia opener Usman Khawaja delivered another classy century on Thursday, remarkably his fourth of the calendar year, as Australia posted 227-3 declared to set Pakistan a target of 351 for victory in the third and final Test.

The tourists would have wanted to make inroads into their opponents' top order before the close, but instead Pakistan reached 73 without loss from the 27 overs they faced after Australia's post-tea declaration.

It means Pakistan require a further 278 runs for victory and Australia need 10 wickets on day five at the Gaddafi Stadium, where something surely has to give.

Australia's men are unbeaten in their last seven Tests (W4 D3), and Pakistan have not lost any of their last five (W3 D2).

The Australians have been beaten only once by Pakistan in the last nine Tests between the sides, yet Pakistan have just a single defeat in their last 12 Tests at this ground, and that was against Sri Lanka all the way back in March 2002.

After draws in Rawalpindi and Karachi, this match looks ripe to produce a victory for one of the teams, but it could easily go either way.

Australia were 11-0 at the start of play and reached 96 without any loss when Shaheen Shah Afridi bowled David Warner for 51 with a sensationally good delivery. Khawaja kept going and anchored the innings with 104 not out, Marnus Labuschagne weighing in with 36 and Steve Smith passing 8,000 career Test runs in making 17.

Captain Pat Cummins declared early in the late-afternoon session, once the lead passed 350, but Abdullah Shafique (27 not out) and Imam-ul-Haq (42 not out) helped Pakistan to the close without any damage.

Shafique used up a life moments before the close when he edged spinner Labuschagne past the left hand of Smith at first slip, potentially a highly costly miss by the fielder.

Khawaja does it again

Khawaja, who was born in Pakistan, did not play a Test between matches against England in August 2019 and January of this year. It is testament to Australia's resources that they could afford to leave out a batter of his quality. The 35-year-old made 91 in the first innings of this match and surpassed that second time around.

He now has 751 runs in five Tests this year, far and away the most of anyone in Tests. Shafique is second on that list, with 397 runs and counting.

Record for Smith, but dropped catch sours his day

Australia would have ended the day on a high if Smith had clung on to the sharp chance from the penultimate delivery of the day. Shafique drove aggressively at Labuschagne, who drew the edge but saw the ball race away to the boundary rather than stick in Smith's claw.

Smith earlier reached his runs landmark in his 151st Test innings, the fewest of any batsman to have reached 8,000 Test runs.

UK Prime Minister Boris Johnson has dismissed the notion of Russia hosting Euro 2028 as "beyond satire", instead suggesting the tournament be awarded to Ukraine.

Russia launched a bid for either Euro 2028 or Euro 2032 on Wednesday, despite the country's ongoing invasion of their Eastern European neighbour.

That puts the 2018 World Cup hosts against a joint United Kingdom and Republic of Ireland bid for the former, an Italy bid for the latter and a Turkey bid for either event.

"The idea of Russia holding any idea of football tournament or any kind of cultural event right now is beyond satire," Johnson said in Brussels, where a Nato summit addressing Vladimir Putin's invasion is taking place.

"I can’t believe that anybody would seriously consider their suggestion."

Johnson appeared to forget that his own country had bid for Euro 2028 when he subsequently suggested the best path would be to hand it to Ukraine, who jointly hosted Euro 2012 with Poland.

"I think the best thing possible would be for the entire Russian forces to retire forthwith from Ukraine and hand the tournament to them," Johnson added.

Last year's rearranged Pan-European edition saw Italy triumph over England in a penalty shoot-out final at Wembley Stadium.

Hosts will be confirmed for 2028 and 2032 in September 2023, ahead of the next edition in Germany in 2024.

Former Tottenham and England forward Jermain Defoe has confirmed his retirement at the age of 39.

The Sunderland striker, who spent time with Spurs in three different stints, also played for West Ham, Portsmouth, Toronto FC, Bournemouth and Rangers across a two-decade-plus career.

Defoe had been due to play on until the end of the season with the League One club after rejoining from Rangers in January, but confirmed his plans to hang up his boots in a lengthy statement published on social media on Friday.

"After 22 years in the game, I have decided to retire from professional football," he stated.

"It's been a really tough decision, and one I have discussed with my family and those closest to me.

"I made my professional debut at 17 years old in 1999, and I feel now is the right time to bow out. I have had an incredible journey and have met some amazing people in the game.

Initially coming through the youth ranks at Charlton and West Ham, Defoe scored on his debut in the League Cup for the Hammers against Walsall to kick-start a prolific career.

He won a subsequent medal in the same competition for Tottenham in 2008, despite leaving midway through the campaign and missing the final. He was finally presented with the medal in 2018.

Defoe won his only other club honour last year when he helped Rangers to the Scottish Premiership title under former England team-mate Steven Gerrard.

For the Three Lions, he won 57 caps and scored 20 goals, including bagging the winner in a 1-0 victory against Slovenia in the group stage of the 2010 World Cup.

"Football will always remain in my blood, and it gives me great pride and satisfaction to look back on the blessed career that I've had," he added.

"I now look forward to spending some quality time with my friends and family before moving forward on this next chapter in my career.

"Thank you to all the fans from each club I've played for. The love I have received and endured throughout my career will never be forgotten, and I will always have a special bond with you all."

Lionel Messi has been urged by player-turned-pundit Jerome Rothen to quit Paris Saint-Germain after just one season.

The Argentine forward signed a lucrative two-year deal last August after being turfed out of Barcelona when the Spanish club realised they could not afford to register him.

It meant there was the tantalising prospect of Messi teaming up with Neymar and Kylian Mbappe at the Parc des Princes, but they have only featured together in fits and starts due to illness and injury.

PSG hoped to storm the Champions League but were eliminated by Real Madrid at the last-16 stage after squandering a 2-0 aggregate lead during the second leg in Spain.

Messi has managed just two Ligue 1 goals, and seven in all competitions, meaning that for the first time since 2005-06 at Barcelona, he could finish a season with a single-figure goals haul.

"The love story was never made with PSG," Rothen said on his RMC Sports programme. "For everyone's sake, it should end in June."

Barcelona have said they would not close the door on Messi returning to Camp Nou, now that they appear in a better position to sign players.

That still seems unlikely but may be an option on the table should Messi agree his time in France has been a rare career misstep.

Messi missed PSG's weekend defeat to Monaco due to flu but has been able to travel to Argentina this week to join up with his national team.

He was booed during PSG's recent 3-0 home win against Bordeaux in the wake of the Champions League exit, an unusual experience for a player used to being feted by fans.

According to Rothen, who played in the PSG first team from 2004 to 2009 and won 13 caps for France, there has been questionable commitment from a number of South American stars to the PSG cause.

"These things shock me," Rothen said. "He isn't the only one in a few years who has functioned like this with Paris Saint-Germain. We've seen South Americans pull faces from time to time, be physically a little amorphous and not play, then they are in full possession of their means with the national team.

"It's a shame the relationship [Messi] has with Paris Saint-Germain today. Will these 10 days [with Argentina] give him some comfort so that things go better with PSG? I'm still very sceptical about it."
