Roger Federer has revealed he has suffered an injury 'setback' that has forced him to withdraw from the Olympics.
Federer missed 16 months of tennis as he battled his way back from double knee-surgery, although he has played the last two Grand Slam tournaments at Roland Garros and Wimbledon.
Earlier this year he named the Olympics as one of his priorities for the season, but those hopes are now over.
He has said, however, that he should be returning to the ATP Court 'later this summer,' with the US Open appearing the most likely tournament.
“During the grass court season, I unfortunately experienced a setback with my knee, and have accepted that I must withdraw from the Tokyo Olympic Games,” the Swiss announced on social media.
“I am greatly disappointed, as it has been an honour and highlight of my career each time I have represented Switzerland.
"I have already begun rehabilitation in the hopes of returning to the tour later this summer.
“I wish the entire Swiss team the best of luck and I will be rooting hard from afar. As always, Hopp Schwiz! (Go Switzerland!)”
Roger Federer has won two Olympics medals previously: A gold in the men's doubles with Stan Wawrinka in 2008 and a silver in the singles in 2012.
