Federer has made clear he intends to continue playing in 2021, when he will return 40 in August.
But speaking in an interview with GQ, Federer conceded his injury has made him consider whether to continue playing.
“It has definitely been a big moment for me, with the coronavirus and the two operations I have had on my knee and I have had to consider if I really want to keep going [with my career],” he said.
“It is easy for me to say that I do right now, but it is a long road back and I have to be patient with my recovery. But speaking more generally about the coronavirus, I think it is a time for reflection and for us all to remember what is really important in life – family, friends, health. And you go back to basics really.
