Roger Federer has withdrawn from the French Open to protect his body despite reaching the fourth round.
"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.
He had been due to face Italian ninth seed Matteo Berrettini on Monday.
"After discussions with my team, I've decided I will need to pull out of Roland-Garros today," Federer said in a statement released by French Open organisers.
"I am thrilled to have gotten three matches under my belt.
