Carson Palmer was 5 for 5 for 84 yards and a touchdown in his only series and the Arizona Cardinals spoiled Bill O'Brien's first game as Houston's coach with a 32-0 rout of the Texans on Saturday night.

Ryan Fitzpatrick had a rough debut as Houston's quarterback. Playing the entire first half, he completed 6 of 14 passes for 55 yards with two interceptions as the Cardinals took a 20-0 lead at the break.

Arizona rookie Logan Thomas played the entire second half, completing 11 of 12 passes for 113 yards and a touchdown.

The Texans were without wide receiver Andre Johnson, running back Arian Foster and cornerback Johnathan Joseph — all nursing minor injuries.
