Roger Federer has pulled out of this summer’s Tokyo Olympic Games because of a knee injury.
The Swiss, who turns 40 next month, picked up the problem during the grass court season and was last seen when losing in straight sets in the quarter-final at Wimbledon last week.
Prior to that, he had withdrawn from the French Open after winning his third round match to save himself for the grasscourt campaign.
“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,” Federer said on Twitter.
“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.”
Federer won the gold medal in the doubles at the 2008 Games in Beijing and a silver medal in the singles four years later in London.
