Fourteen weeks later, the age-old rivals will renew their feud with playoff possibilities on the line and frigid temperatures adding to the setting of what will be the 200th all-time meeting between the teams (including the postseason).
It's a rivalry with more longevity than any other as the Bears and Packers will become the first teams to play each other on 200 occasions with Green Bay looking to add on to its 98-95-6 lead in the all-time series -- a mark buoyed by the Pack winning six of the last seven, including this year's season opener, 10-3.
For this game in particular, it's very much a must-win for the Bears (7-6), who have a slim shot at returning to the playoffs a season after winning the NFC North, which is currently led by the Packers (10-3). Should Chicago lose and the Rams or Vikings win, the Bears will be eliminated from postseason contention. It's a stark difference for the Packers, who can clinch a playoff spot with a victory coupled with a Rams defeat.
And, of course, there's always a measure of bad blood.
