After taking a 7-0 lead on a Jay Cutler 4-yard touchdown strike to tight end Greg Olsen, the Bears offense got the ball back and proceeded to again march down the field, at one point facing first and 10 at the Buffalo 21-yard line. But the offense self-destructed in the form of three costly penalties that pushed the Bears back and forced Robbie Gould to attempt a 42-yard field goal, which he missed wide right.
Buffalo took over with under two minutes left in the half, and with the help of a Charles Tillman 15-yard penalty for a late hit out of bounds, the Bills were able to move the football and tie the game on a Ryan Fitzpatrick 14-yard touchdown toss to Roscoe Parrish.
For the most part, it was a very good half for Cutler, who completed 11 of 18 passes for 129 yards and one touchdown.
The defense only allowed Buffalo to manage 114 total yards, with 68 of those yards coming on the final scoring drive of the half.
