Hoping to rebound from their Sunday night loss to the Packers, the Bears played their Week 2 home opener against the defending Super Bowl champions, the Pittsburgh Steelers. The Steelers took an early lead in the first quarter as quarterback Ben Roethlisberger completed a 1-yard TD pass to tight end Matt Spaeth, but the Bears immediately fired back in the second quarter as quarterback Jay Cutler completed a 7-yard TD pass to tight end Kellen Davis to tie the score 7-7. In the third quarter, Pittsburgh retook the lead once more as Roethlisberger got a 2-yard run, but Chicago would rally in the fourth quarter as Cutler threw a 7-yard touchdown pass to rookie wide receiver Johnny Knox. The Steelers would then miss 2 field goal attempts, as the Bears drive the ball down to Steelers territory, ending the drive with kicker Robbie Gould's 44-yard field goal, to give the Bears the lead. The Steelers then fumbled the ball on the ensuing kickoff, ending any chance for a last second hail mary.
