Steve Nash received two epidurals in his back and a cortisone shot in his hip on Thursday, and he's doubtful to play in Game 3 on Friday. Steve Blake (strained hamstring) is out indefinitely and Jodie Meeks (ankle) is questionable, which means Darius Morris and Chris Duhon may be the last guards standing as L.A. attempts to erase an early 0-2 deficit vs. the Spurs.
