Knee injury: Wells not starting second half

Beanie Wells has not returned to the game for Arizona since suffering a sprained knee in the first half against Pittsburgh.

Alfonso Smith has replaced Wells. Smith has a 1-yard touchdown run.

The Cardinals miss Wells' physical running and lack sufficient depth behind him after losing rookie Ryan Williams to a season-ending knee injury. But with situational back LaRod Stephens-Howling getting free for a 73-yard touchdown reception, the Cardinals trail only 17-14 with 9:26 left in the third quarter.
