Kolb's Cardinals beat Raiders in final minute

Kevin Kolb played just two series for the Arizona Cardinals on Thursday night, unofficially beginning a new era for a team in desperate need for stable No. 1 quarterback but only willing to dip its toes in the water for a preseason opener.

Kolb completed four of his seven passes for 68 yards against the Oakland Raiders, including a 43-yarder to Larry Fitzgerald, the franchise cornerstone wideout who lobbied to get the former Eagles quarterback in a Cardinals uniform.

After the first quarter, Kolb handed the ball over to the backups and Arizona eventually won the game, 24-18, on Isaiah Williams' 28-yard touchdown catch in the final minute.

Starting Raiders quarterback Jason Campbell also played just two series, completing 6-of-9 passes for 66 yards. Kyle Boller was 7-of-8 for 42 yards and new addition Trent Edwards saw the bulk of the snaps, passing for 140 yards and a touchdown on 10-of-19 passing.
