Paris: Former world number one Roger Federer has withdrawn from the French Open a day after winning his third-round match, organisers said on Sunday.
The 2009 Roland Garros champion took to Twitter to inform his followers about his decision.
"After discussions with my team, I decided that I should withdraw from the French Open," Federer said in a statement released by the French Tennis Federation.
"After two knee operations and more than a year of rehabilitation, it's important that I listen to my body and not rush back into competition," the 39-year-old Swiss added.
Federer, who has hardly played in the last 17 months because of a knee injury, suffered physically in his four-set victory over German Dominik Koepfer on Saturday and decided to end his Roland Garros campaign ahead of what would have been a punishing fourth-round match against Italian Matteo Berrettini.
