Kolb was beat out for the starting job in the preseason by John Skelton, a third-year pro from Fordham who went down late in the opener against Seattle with an ankle injury. Kolb came on to direct the winning touchdown drive against the Seahawks and helped the team get off to a 4-0 start.
But Kolb went out with a rib injury against Buffalo and had not been able to return.
The Cardinals have alternated between Skelton and rookie Ryan Lindley as they have been mired in a nine-game losing streak.
