During the final moments of a tight game Sunday night, Pittsburgh relied on its old standbys. Troy Polamalu and Ben Roethlisberger. Polamalu returned a fumble 16 yards to give Pittsburgh the lead, and Roethlisberger drove the Steelers 60 yards to set up Shaun Suisham for a 38-yard field goal with 4 seconds left that sent the Steelers to a 23-20 victory at Indianapolis.
