Whisenhunt optimistic Warner may play this week

Posted: Updated:

TEMPE, Ariz. (AP) -- Coach Ken Whisenhunt says he had a long talk with Kurt Warner on the flight home, and the quarterback was alert
and upbeat following a blow to the head in Sunday's' victory over St. Louis.

Still, Warner's availability to practice this week or play Sunday at Tennessee will depend on how he does in the mandatory "baseline test" of his cognitive functions. Whisenhunt says the test probably will be administered on Tuesday.

Warner's head was slammed into the turf in the second quarter. He stayed in the game to complete the touchdown drive, then left for good. Whisenhunt says that Warner had concussion-like symptoms and would not have gone back in the game under any circumstances.
