Roger Federer will miss next month’s Rio Olympics and the rest of the tennis season, the 17-time Grand Slam champion with 88 career singles titles announced on Tuesday. 

"I have made the very difficult decision to call an end to my 2016 season as I need more extensive rehabilitation following my knee surgery earlier this year," the 34-year-old Swiss tennis player posted to his Facebook account. 

"The doctors advised that if I want to play on the ATP World Tour injury free for another few years, as I intend to do, I must give both my knee and body the proper time to fully recover."

Federer, who will turn 35 on Aug. 8, underwent arthroscopic surgery for torn cartilage in his left knee on Feb. 3, stemming from a freak bathtub mishap, and then won the Monaco Masters in April. However, he was beset by back problems that forced him to withdraw from the French Open a month later. He then rebounded at Wimbledon earlier in July, only to lose to Milos Raonic in the semifinals.
