Center David West will miss at least two weeks with a fractured left thumb, the Warriors announced after Wednesday night's 121-100 win over Oklahoma City. The absence of West, who enters most games late in the first quarter, signals a change to Golden State's rotation. West's 2.8 rebounds and 11.5 minutes per game would be career lows if they hold. Not since his rookie year with the Hornets, when he backed up P.J. Brown, has West averaged fewer than his current four points per game. West's past two games, in which he has totaled 14 points on 7-of-9 shooting, six assists and two steals, have reinforced the savviness he brings a talent-laden lineup.
