Hoping to rebound from their loss to the Cleveland Browns, the Indianapolis Colts remained at home for a week three intra-conference matchup with the Pittsburgh Steelers on Sunday night.  Indianapolis trailed early in the first quarter as Steelers kicker Shaun Suisham got a 48-yard field goal, followed by quarterback Ben Roethlisberger completing an 81-yard touchdown pass to wide receiver Mike Wallace.  The Colts would answer in the second quarter with a 21-yard field goal from kicker Adam Vinatieri, followed by defensive end Jamaal Anderson returning a fumble, forced by Dwight Freeney, 47 yards for a touchdown.  Another defensive turnover allowed the Colts and Vinatieri to score a 25-yard field goal, giving them a 13-10 lead at halftime.  After a scoreless third quarter, Pittsburgh took the lead in the fourth quarter with a Suisham 44-yard field goal, followed by safety Troy Polamalu returning a fumble 16 yards for a touchdown.  Indianapolis would tie the game again on running back Joseph Addai's 6-yard touchdown run with 2:15 remaining in the game. However, the Steelers were able to capture the win with a final 38-yard field goal from Suisham, dropping the Colts to 0-3.
