Golden State star Stephen Curry has a bruised lower left leg that sidelined him for Wednesday night's game at Dallas, and could keep him out for the second day of a back-to-back in Houston. As for whether interim coach Luke Walton is relieved that an MRI didn't reveal something more serious, that's not quite accurate. ''A relief is if they said he was playing and that he was healthy,'' Walton said with a smile before the matchup with the Mavericks.
