The Bills responded with quarterback Ryan Fitzpatrick completing a 14-yard touchdown pass to wide receiver Roscoe Parrish. The Bears regained the lead in the third quarter with a 1-yard touchdown run from running back Chester Taylor. Buffalo answered with running back Fred Jackson getting a 4-yard touchdown run (with a blocked extra point). Chicago trailed in the fourth quarter as fullback Corey McIntyre got a 1-yard touchdown run, yet they came right back as Cutler found wide receiver Earl Bennett on a 2-yard touchdown pass, followed by a successful two-point conversion pass to running back Matt Forte. The Bears would eventually take the win as a Fitzpatrick throw was intercepted by cornerback Tim Jennings.
