Coming off their shutout home win over the Seahawks, the Steelers flew to Lucas Oil Stadium for a primetime game against the Indianapolis Colts on Sunday night (Pittsburgh's first primetime game of the year).  Pittsburgh scored first in the first quarter with a 48-yard field goal by kicker Shaun Suisham, followed by quarterback Ben Roethlisberger finding wide receiver Mike Wallace on an 81-yard touchdown pass.  The Colts answered in the second quarter with kicker Adam Vinatieri getting a 21-yard field goal, followed by defensive end Jamaal Anderson returning a Roethlisberger fumble caused by Dwight Freeney 47 yards for a touchdown. Vinatieri got another 25-yard field goal before the end of the half.  After a scoreless third quarter, the Steelers regained the lead in the fourth quarter with a 44-yard field goal from Suisham, followed by safety Troy Polamalu returning a fumble forced by James Harrison 16 yards for a touchdown.  However, Indianapolis replied with running back Joseph Addai getting a 6-yard touchdown run. Pittsburgh prevailed, however, with Shuisham hitting a game-winning 38-yard field goal with 4 seconds remaining.
