Coming off their win over the Raiders, the Steelers flew to Ralph Wilson Stadium for a Week 12 intraconference duel with the Buffalo Bills.  Pittsburgh delivered the opening punch in the first quarter with a 1-yard touchdown run from running back Rashard Mendenhall.  The Steelers would add onto their lead in the second quarter with a 45-yard and a 46-yard field goal from kicker Shaun Suisham.  Suisham sets the NFL record with all 4 FGs being 40+ yards & with the OT game winner. The Bills answered in the third quarter with quarterback Ryan Fitzpatrick completing a 65-yard touchdown pass to running back Fred Jackson.  Buffalo continued to creep closer in the fourth quarter as kicker Rian Lindell got a 29-yard and a 32-yard field goal.  Pittsburgh regained the lead with Suisham's 48-yard field goal, but the Bills tied the game again with Lindell making a 49-yard field goal.  In overtime, the Steelers got the last laugh as Suisham nailed the game-ending 41-yard field goal.
