Terrell Owens, who has placed himself among the all-time leading receivers with plans to play a 16th season, has undergone surgery to repair a torn ACL in one of his knees following a previously undisclosed injury this offseason, according to sources familiar with the injury. Owens was unavailable for comment but sources said the surgery by orthopedist Dr. James Andrews occurred within the past month. One source said Owens was hurt while on site taping a television show for VH1.
