Tennis great Roger Federer will miss the US Open later this month and possibly the rest of the season, after announcing that he needs another knee surgery which will sideline him for "many months."
Federer, who is tied with Rafael Nadal and Novak Djokovic on 20 career grand slams, was noncommittal about his future in tennis.
Federer missed more than a year of action after having two operations on his knee after the Australian Open in 2020.
He returned for the 2021 French Open but withdrew after his third-round win to protect his knee. Federer then lost in the quarterfinals at Wimbledon in June.
After his Wimbledon loss, he withdrew from the Tokyo Olympics after announcing an injury setback with his knee.
