With a victory over the Dallas Cowboys, the Chicago Bears would bring themselves within a game of the leading the NFC North division.
The Bears can match that mark with a victory over the Cowboys. While a win over Dallas would give the Bears the same record as the Lions, Detroit would hold the tie-breaker as the results of the head-to-head record between the two teams.
Needless to say, the Bears need to defeat the Cowboys on Monday. If the Bears fail to come up with a victory on Monday, not only would team remain a virtual 2 games behind the Lions, but the team would also be in third place in the NFC North division. The Green Bay Packers defeated the Atlanta Falcons on Sunday and would move into second place if the Bears lose to the Cowboys on Monday.
With Aaron Rodgers inching closer to a return, the Bears can not afford to be behind the Packers. Especially when the Bears have a game against Green Bay looming at the end of the season.
After the Lions loss and Packers victory on Sunday, the Bears now face a must-win situation against the Cowboys on Monday.
