TEMPE, Ariz. (AP) -- Arizona quarterback Kevin Kolb went through a substantial practice for the first time since his injury three weeks ago and says he is optimistic he will be able to play Sunday at St. Louis.
Kolb, who says he took 35 to 40 reps in Wednesday's workout, has been frustrated by his slow recovery from a right turf toe and bruise on the side of the same foot. He was injured in the Cardinals' 30-27 loss at Baltimore on Oct. 30.
Backup John Skelton started in wins over St. Louis and Philadelphia, but struggled in Arizona's 23-7 loss at San Francisco last Sunday.
Coach Ken Whisenhunt says whether Kolb starts against the Rams will depend largely on how his foot responds to the increased practice.
