Passage: Hoping to rebound from their loss to the Redskins the Cowboys played at home ground for an NFC duel with the Bears. In the first quarter Dallas trailed early as kicker Robbie Gould nailed a 38-yard field goal. Then they replied with WR Dez Bryant returning a punt 62 yards to the endzone for a touchdown. The Bears got the lead back when QB Jay Cutler made a 39-yard TD pass to TE Greg Olsen. In the 2nd quarter the Cowboys replied again when QB Tony Romo made a 1-yard touchdown pass to RB Chris Gronkowski, but fell behind with Cutler making a 9-yard TD pass to WR Devin Hester, followed by kicker Robbie Gould making a 40-yard field goal. In the third quarter Dallas would reply with kicker David Buehler nailing a 28-yard field goal. However, they continued to struggle in the fourth quarter when Cutler made a 3-yard TD pass to RB Matt Forte, but the Cowboys made the final score of the game when Buehler got a 48-yard field goal.
