Kevin Kolb practices, could start

TEMPE, Ariz. -- Arizona's Kevin Kolb increased his participation in practice on Thursday and coach Ken Whisenhunt was optimistic his quarterback would do the same in Friday's workout.

That could mean Kolb will be back at the controls on Sunday against Cleveland. A knee to the head on Arizona's third play put him out of last week's game against San Francisco. Backup John Skelton came on to lead the Cardinals to a 21-19 victory, their third straight win and fifth in six games.

Meanwhile, safety Kerry Rhodes has gone through two full practices and appears ready to return to game action. Rhodes has been out for eight games with a broken bone in his left foot.
