Tim Duncan (knee) is considered doubtful to play again on Friday. Duncan didn't really have much of a chance to play on Friday and the Spurs will treat him with kid gloves until he's 100 percent healthy. Likely without Duncan and Manu Ginobili (hamstring, doubtful), the Spurs will be led by Tony Parker and get ample help from guys like Boris Diaw, Danny Green and Kawhi Leonard.
