Answer based on context:

Following the Packers miraculous 37-36 comeback win against the Dallas Cowboys, the Packers returned to snowy Lambeau Field to take on the Pittsburgh Steelers. Once again, Aaron Rodgers was inactive and Matt Flynn got the start. The two teams traded TDs in the first quarter, and Eddie Lacy ran 14 yards for a TD at the 2-minute warning. Pittsburgh responded with a 31-yard field goal to make it 10-14 at halftime. In the 3rd quarter, both teams once again traded TDs to make it 17-21. Pittsburgh then took the lead with an 11-yard TD pass to Matt Spaeth. On the Packers' next drive, Matt Flynn collided with Andrew Quarless, disrupting a pass that was intercepted and returned 40 yards for a TD by Cortez Allen to extend their lead 31-21. In the 4th quarter, The Packers managed to tie the game with a 22-yard field goal and a 1-yard run by John Kuhn. With a little less than 3 minutes remaining, Troy Polamalu forced a Matt Flynn fumble at the Packers 17. The Steelers took a 38-31 lead with a 1-yard TD run from Le'Veon Bell. After a 70-yard kick return by Micah Hyde, the Packers were at the Steelers 31-yard line with 1:25 remaining. 3 plays later they reached the Steelers 1-yard line. However, a false start penalty both pushed them back 5 yards and ran 10 seconds off the clock, leaving the Packers with one play to get into the endzone. On the final play, Matt Flynn's pass for Jarrett Boykin was incomplete, and time expired. With the 38-31 loss, The Packers fell to 7-7-1, and their playoff hopes rested on the outcomes of the games played by the Detroit Lions (7-7) and the Chicago Bears (8-6). Detroit lost to the New York Giants 23-20 in OT and was eliminated from playoff contention. Meanwhile, Chicago had an opportunity to clinch the NFC North division with a win over the Eagles on Sunday Night Football, but the Eagles beat the Bears 54-11. This set up a win-and-in matchup between Green Bay (7-7-1) and Chicago (8-7) the following week. The winner would obtain the 4th seed in the NFC playoffs, and the loser would be eliminated from playoff contention.
