Among the weapons of the Packers offense that the Bears must attempt to hinder was the running game, as Green Bay's rookie running back Eddie Lacy has recorded over 100 yards per game in the previous six during the season, along with quarterback Aaron Rodgers. One of Rodgers' skills is passing balls longer than 20 yards, and was 16 of 32 on these attempts, which was tied with Russell Wilson of the Seattle Seahawks for the highest percentage in the league; the Bears allowed 57 percent of opponents to throw for the aforementioned distance, the second-worst score in the NFL.

On the Packers' first drive, Rodgers failed to recognize the Bears' zone defense, having expected a man-to-man defense, and Shea McClellin escaped Don Barclay's block and, along with Isaiah Frey, pulled Rodgers down, who landed on his shoulder and injured his left collarbone, and was replaced by Seneca Wallace for the remainder of the game. Afterwards, Mason Crosby kicked the 30-yard field goal to give the Packers the lead. On Chicago's first drive, McCown escaped pressure from Mike Neal and threw towards Brandon Marshall for the 7-3 lead. Once the Packers got the ball back, Wallace's pass for Jordy Nelson was tipped and intercepted by Julius Peppers, and was returned 14 yards to Green Bay's 45-yard line, but after the Bears failed to convert on third down, Adam Podlesh's punt was blocked by Jamari Lattimore. Eventually, James Starks ran 32 yards for the touchdown. However, the Bears traveled 60 yards on two plays, and Fort&#233; scored on the 1-yard run. The Bears ended the first half with Robbie Gould's 24-yard field goal to expand the lead to 17-10. In the third quarter, the Packers forced the Bears to punt, and Lacy ran 56 yards to the Bears' 1, and scored on the ensuing play. On the eventual kickoff, the Packers successfully attempted a surprise onside kick, which was recovered by Lattimore. Crosby kicked a 23-yarder on the drive. On the Bears' next drive, McCown threw a six-yard pass to Alshon Jeffery, whose size kept the ball from being knocked away by Davon House. After both teams exchanged punts in the fourth quarter, on the Bears' next drive, began attempting to run out the clock. On 4th and 1 at the Bears' 32 with 7:50 remaining, Fort&#233; ran three yards for the conversion and continuing the drive, which ended with Gould's 27-yard field goal. The drive lasted 18 plays and took up 8:58, leaving only 50 seconds remaining in the game.
