Coming off their road win over the Lions, the Steelers went home for a divisional match with the Cleveland Browns.  After a scoreless first quarter, Pittsburgh came out striking in the second quarter as quarterback Ben Roethlisberger completed an 8-yard touchdown pass to tight end Heath Miller and a 52-yard touchdown pass to wide receiver Hines Ward.  The Browns immediately struck back as wide receiver Joshua Cribbs returned a kickoff 98&#160;yards for a touchdown. Pittsburgh would close out the half with a 32-yard field goal from kicker Jeff Reed. Cleveland tried to catch up as quarterback Derek Anderson completed a 1-yard touchdown pass to fullback Lawrence Vickers, yet the Steelers answered with a 2-yard touchdown run from running back Rashard Mendenhall.  Pittsburgh would then close the game out in the fourth quarter with Reed kicking a 39-yard field goal. With their 12th-straight win over the Browns, the Steelers improved to 4-2.  With the Ravens' loss to the Vikings, and the Bengals' loss to the Texans that same week, the Steelers are now tied with the Bengals at the top of the AFC North.
