Roger Federer announced on Sunday that he has suffered another injury setback, one that requires his third knee surgery in the last 18 months.
In an Instagram video, Federer said that he opted for another operation that will put him "on crutches for many weeks and then also out of the game for many months.”
“I want to be healthy," Federer said. "I want to be running around later, as well, again, and I want to give myself a glimmer of hope, also, to return to the tour in some shape or form,” Federer said.
