Hoping to rebound from their home loss to the Panthers, the Cardinals flew to Soldier Field for a Week 9 duel with the Chicago Bears.  Arizona would deliver the opening strike in the first quarter as quarterback Kurt Warner completed an 11-yard touchdown pass to wide receiver Larry Fitzgerald.  The Bears would respond with quarterback Jay Cutler hooking up with tight end Greg Olsen on a 33-yard touchdown pass, yet the Cardinals would answer with Warner finding tight end Ben Patrick on a 6-yard touchdown pass.  In the second quarter, Arizona would unleash a firestorm as Warner found Fitzgerald again on a 17-yard touchdown pass, followed by tight end Anthony Becht on a 15-yard touchdown pass.  Afterwards, the Cardinals would close out the half with a 43-yard field goal by kicker Neil Rackers. In the third quarter, Arizona would get the period's only points as Rackers booted a 30-yard field goal.  Chicago would begin to rally in the fourth quarter as Cutler found Olsen again on a 3-yard and a 20-yard touchdown, yet the Cards closed out the game with Warner hooking up with wide receiver Steve Breaston on a 4-yard touchdown pass.
