PARIS, May 24 (UPI) --
French tennis star Gael Monfils Thursday withdrew from the 2012 French Open because of an injured right knee.
Monfils, 25, ranked No. 13 in the world, made it to the semi-finals last year in the French Open, which begins Sunday in Paris.
The Frenchman lost to American Brian Baker Wednesday in the second round of the Open de Nice Cote d'Azur tournament in Nice.
