Golden State Warriors All-Star power forward David Lee had surgery Thursday to repair a torn right hip flexor, an injury that forced him out of the starting lineup and limited his minutes in the playoffs. The procedure was performed by Dr. William Meyers at the Vincera Institute in Philadelphia, the team said. Lee will start rehabilitation in the next 10 to 14 days. No further timetable on his recovery was announced. At the end of last season, Lee had surgery to repair a torn abdominal muscle and returned before the start of training camp.
