Answer based on context:

In a Thursday Night showdown against the rival Green Bay Packers, the Bears struggled throughout much of the game, and the offense was only able to muster one touchdown and 168 yards. Quarterback Jay Cutler was sacked seven times, and completed 11 of 27 passes for 126 yards with one touchdown, four interceptions and a 28.2 passer rating. Cutler's counterpart Aaron Rodgers was sacked five times, and ended the game by completing 22 of 32 passes for 219 yards and a touchdown, an interception and a passer rating of 85.3. In the first quarter, Packers kicker Mason Crosby opened the game with a field goal, and the Bears would fall behind even more when Packers holder Tim Masthay threw a pass to tight end Tom Crabtree on a fake field goal. In the third quarter, Matt Forte sustained an ankle injury (originally reported as a high ankle sprain), and was lost for the game. After Cutler was later intercepted by Tramon Williams, Bears linebacker Lance Briggs dropped a possible interception, as Green Bay later increased the lead on another field goal. The Bears would later score on a Robbie Gould field goal, but the Packers later scored ten points (a Crosby field goal and a Rodgers 26-yard touchdown pass to Donald Driver) in 21 seconds early in the fourth quarter. After Tim Jennings intercepted a Rodgers pass, Cutler connected with Kellen Davis to narrow the score to 23-10 with 6:49 left in the game, but the Packers would hold for the win.
