The Bears hosted the 6-5 Seattle Seahawks in Week 13, who had lost five of their first six road games. The Bears started the game strong, with Brian Urlacher forcing Marshawn Lynch to fumble, and the ball was recovered by Kelvin Hayden, and Jay Cutler eventually hit Earl Bennett on a 12-yard touchdown pass. The Bears would later fail twice to expand their lead; first, Lovie Smith called for Michael Bush to run up the middle on fourth-and-one at the Seattle 15, and he was stopped for no gain. On the second occasion, Bennett dropped a potential 62-yard touchdown pass. The Seahawks capitalized on the two blunders, with rookie quarterback Russell Wilson hitting Golden Tate on a 49-yard pass, and eventually scored on Lynch's 4-yard touchdown run. Wilson would complete 23 of 37 passes for 293 yards with two touchdowns and a 104.9 passer rating while rushing for 71 yards on nine carries. Seattle then took the lead on Steven Hauschka's 31-yard field goal to close the half. Seattle would have scored a touchdown on the previous play, but Braylon Edwards dropped the potential 10-yard touchdown pass in the end zone. In the third quarter, Chicago regained the lead on Cutler's 12-yard touchdown pass to Matt Forte, but Wilson would lead the Seahawks 97 yards to take back the lead on a touchdown pass to Tate. Cutler would then hit Brandon Marshall on a 56-yard pass to set up Robbie Gould's game-tying 46-yard field goal. In overtime, the Seahawks won the toss, and Wilson took the offense 80 yards, and threw the game-winning touchdown pass to Sidney Rice. On the play, Major Wright hit Rice while he was catching the ball, appearing to knock Rice unconscious and the ball out of his hands, but the review upheld the touchdown, giving Seattle the victory. The loss dropped Chicago down to 8-4, once again tying them with the Packers for the NFC North lead. The 459 yards allowed are the most by the team all season. This would mark Urlacher's final game in a Bears' uniform. Urlacher was inactive for the final four games of the 2012 season, and he retired from the NFL on May 22, 2013.
