INDIANAPOLIS — Warriors guard Patrick McCaw will miss at least four more weeks with a lumbosacral bone bruise, the team announced Thursday afternoon. McCaw, who sustained the injury on a scary fall in Saturday night's win over the Kings and momentarily lost feeling in his legs, will be re-evaluated by a specialist on May 3. That puts his earliest possible return at Game 1 of the Western Conference semifinals, forcing him to miss Golden State's final three regular-season games and the first round of the playoffs. With Stephen Curry already expected to miss the first round with a sprained left MCL, the Warriors will try to get through their first postseason series with a depleted backcourt.
