DENVER — An aged Warriors center position received some good news Friday: Rookie Damian Jones, who underwent surgery in June for a torn right pectoral muscle, has been cleared for non-contact work. "He is not allowed to dunk because they don't want him to hurt his shoulder, but we would like to get him out there as much as possible," head coach Steve Kerr said before Golden State's preseason game Friday night against the Nuggets. The 7-foot JaVale McGee, a training-camp invitee, is the front-runner to win the Warriors' 15th and final roster spot. With Jones watching from the bench, Pachulia and Varejao have totaled nine points and 22 rebounds through three preseason games on a combined 2-for-10 shooting. The 7-foot, 245-pound Jones, though a raw prospect, has prototypical NBA size and a developing midrange game.
