Swiss star Federer withdraws from French Open

ISTANBUL

Swiss tennis star Roger Federer confirmed on Sunday his withdrawal from the fourth round of the French Open.

"After discussions with my team, I've decided I will need to pull out of Roland Garros today. After two knee surgeries and over a year of rehabilitation it's important that I listen to my body and make sure I don't push myself too quickly on my road to recovery," Federer said on Twitter.

"I am thrilled to have gotten three matches under my belt. There is no greater feeling than being back on court. See everyone soon," he added.

The 20-time Grand Slam champion pulled out of the Roland Garros after winning his four-set match with German player Dominik Koepfer.
