Cardinals coach Ken Whisenhunt says that he won't decide on a starting quarterback until right before Sunday's game. Kurt Warner and Matt Leinart split practice time with the starters on Thursday. "You want to make the decision now, but certainly we've got to see how everything goes with Kurt," Whisenhunt said. "Even though he may feel great today, there might be a situation where something could come up." Warner suffered a concussion during a Nov. 22 game against the Rams and missed last weekend's game.
