Roger Federer has withdrawn from the French Open to protect his body despite reaching the fourth round.
The 20-time Grand Slam champion took the decision the day after a gruelling third-round win over Dominik Koepfer.
BBC News reports Federer, who won the French Open in 2009, had two knee surgeries last year and had played only three matches in 16 months before arriving in Paris.
He has made no secret that his priority for this year is Wimbledon, which starts on 28 June.
