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.
