Defending champion Dominic Thiem has retired from the US Open and will miss the remainder of the 2021 season after failing to recover in time from a wrist injury.
It comes after five-time winner Roger Federer announced he would be out for “many months” to undergo knee surgery.
Thiem, who beat Alexander Zverev in a five-set classic at Flushing Meadows last year, injured his wrist during the Mallorca Open in June.

And in a statement, the Austrian said: “Unfortunately I had to withdraw from the US Open and will miss the rest of the 2021 season.
“I’m really disappointed that I can’t defend the title in New York, but I haven’t recovered from the wrist injury I suffered in June at the Mallorca Open.
“For the past six weeks, I took medical advice, wore the wrist brace, exercised to stay in shape before I started training on the court again.
“My recovery was going very well, but last week I hit a ball during training and started to feel pain again. I went straight to see the doctors.
“After a few tests they said my wrist needed more time so we all agreed to be careful and give my wrist time to recover.

“I will wear the wrist brace for a few more weeks before starting the exercises and then training with the racket again.
“It was a tough decision to make, but I know it’s the right thing to do. I have a long career ahead of me and it’s important not to take risks or rush – which I hope you understand. ‘
This puts an end to the 27-year-old’s hopes of adding another Slam title. Thiem has also been a Slam finalist three times – twice at Roland Garros and once at the Australian Open.
Federer, 40, is set to undergo his third knee surgery in two years and has said he will be “out of the game for months”.
After his surrender in the quarterfinals of Wimbledon against Hubert Hurkacz, this can only fuel fears that he will not be seen again on the biggest stages of sport.

Federer said: “It’s going to be tough in some ways, but at the same time I know it’s the right thing to do because I want to be healthy, I also want to run later.
“I also want to give myself a silver lining to come back to touring in some form or another. I’m a realist – I know how difficult it is at this age right now to have another surgery and have it done. ‘to try.”
“But I want to be healthy. I will follow the rehabilitation process with a goal, while I am still active, which I think will help me during this long period.
