The Cardinals have signed veteran free agent Tim Hasselbeck to a 1-year contract.  Hasselbeck will likely back up Tim Rattay until Kurt Warner is ready to return from injury.  Hasselbeck has played in 11 games in his NFL career and he has completed 95 of 177 passes (53.7%) for 1,012 yards with 5 TD passes and 7 interceptions (63.6 QB Rating) and he also has carried the ball 17 times for 38 yards (2.2 ypc).  The Cardinals will likely be without Kurt Warner for a couple of weeks who has a ligament tear in his left elbow.  Warner has played well this season for the Cards as he has completed 45 of 71 passes (63.4%) for 601 yards with 4 TD passes and 1 interception (103.1 QB Rating).
