Roger Federer says he is unlikely to play Wimbledon next year and has confirmed he will miss the Australian Open as he recovers from injury.
The 20-time Grand Slam champion has not played since losing in the Wimbledon quarter-finals in July and having more knee surgery.
The Swiss, 40, told Le Matin that he does not expect to return to competition until next summer.
"I would be extremely surprised if I could play Wimbledon," he said.
"I will be able to resume running quietly in January and resume sessions on the court with complex support in March or April.
