Coming off their win over the Jagaurs, the Steelers flew to the University of Phoenix Stadium for a Week 7 interconference duel with the Arizona Cardinals, in a rematch of Super Bowl XLIII.  Pittsburgh delivered the game's opening punch in the first quarter as quarterback Ben Roethlisberger found tight end Heath Miller on a 12-yard touchdown pass.  The Steelers would add onto their lead in the second quarter with Roethlisberger hooking up with wide receiver Mike Wallace on a 95-yard touchdown pass.  The Cardinals would answer with running back Alfonso Smith getting a 1-yard touchdown run.  Pittsburgh would close out the half with a 41-yard field goal from kicker Shaun Suisham. Arizona began the third quarter with quarterback Kevin Kolb completing a 73-yard touchdown pass to running back LaRod Stephens-Howling, yet the Steelers responded with Roethlisberger connecting to wide receiver Emmanuel Sanders on a 4-yard touchdown pass, along with Kolb getting called for intentional grounding in his endzone, resulting in a safety.  In the fourth quarter, the Steelers continued to pull away with a 42-yard and a 39-yard field goal from Suisham.  The Cardinals tried to rally with Kolb completing a 2-yard touchdown pass to wide receiver Early Doucet (with a failed two-point conversion), yet Pittsburgh held on to preserve the victory.
