Jamie George and Elliot Daly have withdrawn from England's Six Nations squad due to injury.

Hooker George has been sidelined by concussion after taking a blow in Saracens' European Champions Cup defeat at Edinburgh last weekend.

Versatile back Daly has been ruled out with a hamstring injury as the Red Rose prepare to face Scotland in their first game of the tournament a week on Saturday.

Jamie Blamire and Ollie Lawrence were on Tuesday called up as replacements for the experienced duo.

England head coach Steve Borthwick is also set to be without Courtney Lawes for his first match in charge at Twickenham next week, as the towering lock is struggling with calf injury.

Hooker George McGuigan (knee) is also in the treatment room along with Luke Cowan-Dickie (ankle).

Blamire, Tom Dunn and the uncapped Jack Walker are the remaining hooker options for Borthwick.

Karen Khachanov has defended his decision to publicly show support for the breakaway region of Artsakh, despite drawing the ire of the Azerbaijan Tennis Federation (ATF).

Khachanov – who was born in Russia but has an Armenian father – has written supportive messages on a camera twice during his run to the semi-finals of the Australian Open.

Azerbaijan's blockade of Artsakh, which began in December, is part of the ongoing Nagorno-Karabakh conflict, with the area internationally recognised as part of Azerbaijan despite historically being a part of Armenia.

Following Khachanov's show of support, the ATF wrote to the International Tennis Federation, calling the world number 20's messages a "hateful act".

The statement added: "The ATF condemned this act and demanded that the tennis player be punished and urged the International Tennis Federation to take harsh measures for prevention of such incidents in the future."

Speaking after his quarter-final win over Sebastian Korda, in which the American retired hurt with Khachanov leading by two sets and a break, the Russian defended his actions.

"I say many times. I have Armenian roots," he said. "From my father's side, from my grandfather's side, even from my mum's side. I'm half Armenian.

"To be honest, I don't want to go deeper than that, and I just wanted to show strength and support to my people. That's it."

On whether he had heard from the ITF since the complaint was made, Khachanov replied: "I didn't hear anything about that," adding that he has also not been told to stop writing the messages on cameras.

Khachanov will play Stefanos Tsitsipas in the Australian Open semi-finals on Friday.

Stefanos Tsitsipas has invited Margot Robbie to watch him at the Australian Open after charging through to the semi-finals in Melbourne.

The Greek tennis star says he is a huge fan of the Australian actor and would love her to support him from the Melbourne Park stands.

His surprise shout-out to Robbie came after Tsitsipas scored a 6-3 7-6 (7-2) 6-4 win against unseeded Czech Jiri Lehecka in the quarter-finals on Tuesday.

Tsitsipas was partway through explaining his impressive display to on-court interviewer Jim Courier, detailing how it took "experience and some good Spartan attitude" to get the better of Lehecka, when he mentioned the 32-year-old Hollywood star.

Robbie, married to English film producer Tom Ackerley, became well known in Australia and the UK for her role in the soap opera Neighbours before turning to Hollywood.

Her career includes prominent roles in movies including The Wolf of Wall Street, Suicide Squad and I, Tonya, as well as being the voice of Flopsy Rabbit in the Peter Rabbit film series.

"Can you hear them? Australia is such a great country," Tsitsipas said, reacting to roars from the crowd.

"I like a lot of great Aussie things. One of my favourite actresses comes from Australia, Margot Robbie."

Former Australian Open champion Courier, surprised by that unprompted mention, said: "Are you pitching right now?"

That prompted Tsitsipas to say: "It would be nice to see her over there one day."

Was that an invitation to Robbie?

"Absolutely," Tsitsipas said.

The 24-year-old Greek player soon stressed that his Robbie fandom was not the main reason for him enjoying Australia.

"That's not it," Tsitsipas said. "The people are very welcoming. I've said that so many times and will keep saying it because it's true.

"I grew up in a place that's very similar in terms of conditions and lifestyle and find myself feeling home when I'm here because it's not too tropical, and it's not too humid, and it very much feels like home.

"The French players have Roland Garros as their home grand slam, the British players have Wimbledon, the Americans have the US Open; for me, the Australian Open is always going to be my home grand slam.

"I would love one day hopefully winning the Aussie Open and giving a bit portion of the prize-money to build a school in Victoria which is the state of education. I'd like to do that."

Stefanos Tsitsipas stormed into a third consecutive Australian Open semi-final with a straight-sets victory over Jiri Lehecka on Tuesday.

Tsitsipas has bowed out at the last-four stage in three of the past four years, but the Greek will get another chance to reach a first final after beating Lehecka 6-3 7-6 (7-2) 6-4.

The third seed from Greece fired down nine aces and hit 36 winners on Rod Laver Arena, winning without having his serve broken to set up a meeting with Russian Karen Khachanov.

Unseeded Czech Lehecka was broken in his first service game and Tsitsipas did not give him a look-in from then on in the first set.

The 21-year-old Lehecka had the favourite in trouble in the fourth game of the second set, but saw five break-point opportunities come and go.

Tsitsipas clinically won the tie-break to move a set away from the semi-finals, but Lehecka put up a great fight but was frustrated when he was unable to convert another three break points before the favourite held to lead 4-3.

Another tie-break looked possible until Lehecka's excellent run in only his second main-draw appearance came to an end when he netted a backhand following a thunderous cross-court winner from a fired-up Tsitsipas.

Tsitsipas maintains perfect quarter-final record

A first major title has so far eluded Tsitsipas, but he keeps knocking on the door and is two wins away from achieving that dream.

The 24-year-old is the fourth male player in the Open Era to be unbeaten in his first six grand slam quarter-finals after Rod Laver, Patrick Rafter, and Andre Agassi.

Jelena Ostapenko was once again left bemoaning the electronic line calling system in place at the Australian Open after her quarter-final defeat to Elena Rybakina.

The Latvian did not blame the system for her loss, with Rybakina sealing a convincing 6-2 6-4 victory on Tuesday, but reiterated her belief that calls are being missed.

When asked following her fourth-round win against Coco Gauff whether she believed in the system, Ostapenko replied with a smile: "Honestly? No."

Speaking after her loss to Rybakina, she again smiled as she said: "I'm not really happy with the system they are using.

"A couple of times it was not even by a couple of centimetres. It was much more than that. But I cannot do anything about it, because it is the way as it is.

"First of all, [the calls] are really late sometimes. You already hit the ball, and then you hear 'out,' which is normally not the way it is with the line umpires. And second of all, some balls were quite, how you say, not a little out. They were [quite] a bit out and they were not called."

The number 17 seed – who suffered her first defeat in nine WTA-level quarter-finals – called for a return of the Hawk-Eye system and line judges, which was replaced at the Australian Open by the electronic system in 2021.

"Honestly, my personal opinion, I wish it would be the Hawk-Eye system and the line umpires, because I feel like that way it's more precise, and much [fewer] mistakes, in my opinion," the 2017 French Open champion added.

"... I think also, that way it looks a little better for me on the court how it is. Not just calling-wise, but in general how the court looks, because with no line umpires, for me, it looks a little empty."

Ostapenko was under no illusion that her own performance had not been at the level it was when she beat Gauff, and suggested that her participation in the mixed doubles late on Monday was a factor.

"I think in general today the level of the match was I think much lower than the previous one," she said. "I felt like me and Coco, we had a really high level of tennis and we played really well. It's a little shame that I couldn't bring this level of the tennis today.

"Obviously [Rybakina] was serving well, but I felt like already in the second set when I had the longer rallies with her, I was winning mostly, so that was my goal to make her play.

"I felt like maybe mixed doubles yesterday was a little bit not the right decision to play that late. But in general I think I can take only positive things out of this week, because it's only the beginning of the season, and if I keep working and keep playing the same way, I think I can be dangerous player."

Victoria Azarenka is through to her first Australian Open semi-final in a decade after beating Jessica Pegula in straights sets.

Azarenka had not reached the last four at Melbourne Park since going on to retain her title in 2013, but ended that wait with an impressive 6-4 6-1 victory over the third seed on Tuesday.

The 33-year-old from Belarus will do battle with Elena Rybakina for a place in the final following a commanding display on Rod Laver Arena.

Azarenka, the 24th seed, stormed into a 3-0 lead and although Pegula got back on serve at 5-3, she was a set down after being broken for a second time.

The experienced Azarenka clinically grasped her first break-point opportunity of the second set but Pegula hit straight back with a break of her own in the next game.

She was unable to turn the tide, though, as an inspired Azarenka dominated the remainder of the set with another two breaks and losing only a further two points behind her serve.

Azarenka, a winner of two mixed doubles grand slam titles since her last major triumph at this tournament 10 years ago, wrapped up the victory in an hour and 37 minutes.

Azarenka moves level with Graf

This quarter-final win for the former world number one took her tally of main-draw victories at the Australian Open to 47.

She is now level with the great Steffi Graf in sixth place on the list of the most women’s singles main-draw triumphs in this tournament in the Open Era.

Azarenka – 0/2
Pegula – 3/2

The New York Giants hope to keep quarterback Daniel Jones at the franchise, general manager Joe Schoen has confirmed.

The 25-year-old is set to become a free agent at the end of the season, and was non-committal when questioned by the media after the Giants' Divisional Round loss to the Philadelphia Eagles on Saturday.

Jones was sacked five times in Philadelphia, but had a solid regular season, throwing 15 touchdowns and rushing for another seven in 16 games, while overall he completed a career-best 67.2 per cent of his pass attempts (317 out of 472).

Regarding his contract, Jones said on Saturday: "We will cross that bridge when we get there. I really enjoyed playing here... We will figure out where that goes, but I have nothing but love and respect for this organisation and the group of guys in the locker room."

Speaking at an end-of-season press conference on Monday, Schoen said: "We'd like Daniel to be here. He said it, there is a business side to it. But we feel like Daniel played well this season. He's done everything we've asked him to... We would like to have Daniel Jones back.

"Hopefully we can get something done with his representatives. That would be the goal, to build a team around him where he could lead us to win a Super Bowl."

Having turned down the chance to exercise the fifth-year option on Jones' rookie contract, it seems the Giants feel he has proven himself worthy and Schoen is eager to get to the negotiating table.

"It takes two. Both sides are going to have that conversation," he said. "We haven't crossed that bridge yet. There are tools at our disposal."

Jonathan Isaac expressed his gratitude to the Orlando Magic for "sticking with me" after he made a "surreal" long-awaited return in a 113-98 win over Boston Celtics.

Isaac had been out since tearing his ACL when the NBA restarted at Walt Disney World in August 2020 and wondered if he would ever be back on court in an NBA game.

The Magic forward's comeback finally came at Amway Center on Monday as Orlando ended the Eastern Conference-leading Celtics' nine-game winning run.

Isaac missed 211 games, but came off the bench to score 10 points, claim three rebounds and produce two steals in an appearance of around nine and a half minutes.

He said: "Much love to the Magic for sticking with me. And the Magic fans were excited, so I was just trying to bottle all that up in one moment. It was surreal."

Isaac added: "There were days where I was like I don't know if I want to keep going.

"But then again, I have to thank Christ. Being able to go back to my faith and say God has me on this journey for a purpose. I know that I was made to play basketball. I was made to give glory to God on this stage."

Isaac understandably felt the pace on his return from such a long absence.

"That kind of first wind got to me. That last minute I could barely talk I was breathing so hard," Isaac said. "But the second rotation in the second half, that four minutes, I started to just relax and just feel good."

Paolo Banchero top scored with 23 points for the Magic, while 26 points apiece for Celtics duo Jayson Tatum and Jaylen Brown were in vain.

Orlando are 18-29 down in 13th place in the Eastern Conference, with Boston leading the way at 35-13.

Giannis Antetokounmpo declared "the band is back together" after he made an impressive return in the Milwaukee Bucks' 150-130 victory over the Detroit Pistons.

Antetokounmpo had missed five games due to a sore left knee but scored 20 of his 29 points in the first quarter of his comeback at Little Caesars Arena on Monday.

Khris Middleton was also back in the line-up for the first time since last month following a knee injury of his own as the third-placed Bucks moved to 30-17 in the Eastern Conference.

Greek superstar Antetokounmpo said: "The band is back together" and added: "'I was trying to be aggressive and some shots fell."

Milwaukee scored an incredible 49 points in the first quarter, only two short of the NBA record, with Antetokounmpo taking centre stage.

Bucks head coach Bucks coach Mike Budenholzer was impressed with the way Antetokounmpo was able to hit the ground running.

"It was impressive to come out and play the way he did," Budenholzer said. "He did a little bit of everything, just like the whole group that in that [first] quarter."

Pistons head coach Dwane Casey feared the Bucks could come out firing.

"The first quarter is what I was afraid would happen," Casey said. "A championship-calibre team came in and put their stamp on the game at the beginning.

"We didn't respond, and that's how you give up a 49-point first quarter. I liked our fight after that, but this is a 48-minute game."

Sebastian Korda is taking plenty of positives away from the Australian Open, despite retiring hurt in his quarter-final against Karen Khachanov.

The American sustained an issue to his right wrist early in the second set, before calling an end to proceedings in the third when trailing 7-6 (7-5) 6-3 3-0.

Speaking at a press conference after his elimination, Korda said it was an issue he originally felt at the Adelaide International 1, where he was beaten by Novak Djokovic in the final.

"I had it a little bit in Adelaide a couple of weeks ago, but then it went away," he said. "During the matches, it was completely fine. Then just one kind of mishit return and it started to bother me a lot of after that.

"I knew what it was right away, right when I hit the return. I kind of felt that spot that I was feeling before. Some forehands I couldn't even hold the racquet. Volleying was almost impossible for me. So it was a little tough."

The number 29 seed was pleased with his work in Melbourne though, adding: "Obviously a lot of positives [to take]. Still a great tournament. My first quarter-final in a grand slam. I'm going to go forward with my head high and keep working."

Khachanov is through to his second-consecutive grand slam semi-final, having also made the final four at last year's US Open.

The Russian – who will face either Stefanos Tsitsipas or Jiri Lehecka next – sympathised with Korda but said he was just focused on getting the job done.

"It's part of the sport," Khachanov said. "It was a tough competitive battle until a certain moment, but at the end of the day you don't know how serious he's injured, right?

"I think the end of the second set, you know, when I pushed through and then took it with 2-0 lead by sets, it's extra pressure to the guy, if especially he has some issues physically.

"I think also the beginning of the third, you know, when you take this [3-0] lead, so from the opponent, the attitude change, it's way tougher to come back, so I think all those things together. I was quite focused and I knew what I had to do, how I had to push. I did it really well."

Elena Rybakina's Wimbledon success last year is helping her to progress at the Australian Open.

The number 22 seed reached the semi-finals after a convincing 6-2 6-4 victory against Jelena Ostapenko on Tuesday.

Fresh from beating world number one Iga Swiatek in the fourth round, the only thing that slowed Rybakina down against the 17th seed was a 20-minute rain delay in the first set.

She got through her quarter-final in just an hour and 19 minutes of play, and pointed to her experience at Wimbledon, which culminated in her maiden grand slam win.

"Of course I got all the experience at Wimbledon, and it's helping me now this time here in Australia and I know what to expect," she said.

"For sure it's just easier in this case after Wimbledon. [I am] feeling good on the court and just really enjoying every match I'm playing here."

Rybakina's serve was a key weapon again, hitting 11 aces and winning 76 per cent (29 of 38) of points on her first serve.

She now has a total of 29 aces in the tournament, the most by a women's player and more than her previous three Australian Open campaigns combined.

"[It is] tough to say for me, because I think compared to other girls, I'm quite tall," she said when asked if hitting aces are an under-used part of women's tennis. "I mean, there [are] other girls which are also strong and tall, but for sure I think it's not only about the height.

"I'm happy with my serve. I guess everybody else needs to think if, in this aspect, they need to work more or not, because some girls, they are fine maybe not with the speed, but they have good angles on the serve. They are opening the court. I think everybody is different, and everybody just trying to do what's best for them on the court."

The 23-year-old will face either Jessica Pegula or Victoria Azarenka in the final four, and is excited by once again being included in the business end of a grand slam.

"Of course in the beginning of the tournament, it feels like, 'Oh, it's such a long tournament'," she said. "Now it seems already close. I'm trying to focus just on one match.

"For sure it's close, that's why everybody I think is now going to try even harder, fight for every ball. It's only good players left. For sure it's going to be tough matches."
