Kurt Warner left Arizona's win over St. Louis last Sunday with a head injury. He could be cleared for action this weekend, but Kent Somers of the Arizona Central writes that the Cardinals should strongly consider starting Matt Leinart in his place. Somers writes that doing so would allow Warner to get right while the team gives themselves another chance to see what they have in Leinart, who they drafted with the 10th pick in the 2006 draft.
