NEW ORLEANS — Warriors guard Patrick McCaw will miss at least four more weeks with a lumbar spine contusion, the team announced Thursday afternoon. McCaw, who sustained the injury on a scary fall in Golden State's March 31 win over the Kings and momentarily lost feeling in his legs, will be re-evaluated by a specialist on May 31. That puts his earliest possible return at Game 1 of the NBA Finals, which could begin as soon as May 31. McCaw, who was re-evaluated by team doctors Thursday, has been cleared to begin modified on-court shooting and running drills.
