Roger Federer to miss rest of season, Rio Games due to knee injury

Tennis star Roger Federer broke the news to fans Tuesday that a knee injury will prevent him from finishing up the 2016 season and competing for Switzerland in the upcoming Rio Olympics. In a Facebook post, the world No. 3 explained he will need "more extensive rehabilitation" after knee surgery to repair a torn meniscus earlier this year:

Federer's announcement means he'll be out of the U.S. Open, just one year after missing the French Open. At the Rio Games, Federer was set to play both singles and doubles for Switzerland. He's won medals at previous Olympics, bringing home a gold for doubles in 2008 and a silver for singles in 2012.

Federer said he plans to return to the courts in 2017.
