Detroit advanced its lead in the NFC North to two games and Green Bay improved to 6-6 Sunday. The Vikings dropped to 6-6 after Thursday's loss to Dallas.

The race for the division championship will leave little room for error in the final four weeks of the regular season.
The Vikings and Packers will most likely have to win their final four games and the division to claim a playoff berth. The Lions have a difficult final stretch, but own the head-to-head tiebreaker against the Vikings. Detroit lost its first meeting with Green Bay and they won't meet again until the season finale.
The Vikings have 1-in-3 odds of making the playoffs and 1-in-6 odds of winning the division according to makeNFLplayoffs.com, arguing the likely path to the postseason would be through the wild card. The Lions are currently the No. 3 seed in the NFC, the Vikings are No. 8 and the Packers No. 9.
Here is a look at the three team's remaining schedules:
