But as the NFL announced Tuesday afternoon, the Seahawks can take it one step further this week against the 49ers. If Seattle wins or ties, then it will lock of the NFC West title and earn a first-round by in the playoffs.

Other playoff scenarios:

The Saints can clinch a playoff spot with two scenarios. The first is by defeating the Panthers and having the Eagles lose or tie, the Cowboys lose or tie and the Cardinals lose. The second is by beating the Panthers and having the Eagles lose or tie, the Cowboys lose or tie, the 49ers lose and the Cardinals tie.
