Hoping to rebound from their loss to the Patriots, the Steelers stayed at home for a Week 11 duel with the Oakland Raiders.  Pittsburgh trailed early in the first quarter as Raiders kicker Sebastian Janikowski made a 41-yard field goal. However that would turn out to be the Raiders' only points of the game. The Steelers took the lead in the second quarter with a 5-yard touchdown run from running back Rashard Mendenhall, followed by quarterback Ben Roethlisberger's 16-yard touchdown run and his 22-yard touchdown pass to rookie wide receiver Emmanuel Sanders.  After a scoreless third quarter, the Steelers added onto their lead in the fourth quarter as Roethlisberger found wide receiver Mike Wallace on a 52-yard touchdown pass.  Afterwards, Pittsburgh punctuated the game with a 16-yard touchdown pass to running back Isaac Redman.
