The surgery was performed in Toronto by Dr. Brent Graham. Parker must wear a cast for three weeks before he can begin rehabilitation.
Parker averaged a career-high 12.5 points last season, second only to Chris Bosh on the Raptors. He also averaged 4.1 rebounds and 2.2 assists and became just the third player in team history to start all 82 regular-season games.
Parker's procedure came eight days after Raptors forward Andrea Bargnani had nasal surgery in Milan, Italy, to remove his adenoids and repair a deviated septum. Bargnani, who must wait two weeks before resuming basketball workouts, was injured in a March 17 game at Utah when he was elbowed by teammate Jamario Moon while going for a loose ball.
The first overall pick in the 2006 draft, Bargnani averaged 10.2 points and 3.7 rebounds in 78 games for Toronto last season, including 53 starts.
