Over the last few decades, the Detroit Lions have played a lot of meaningless games on Thanksgiving Day.

But this year, not only does the annual Turkey Day fixture mean a whole lot — Detroit is currently fighting to stay atop the NFC — it could also be a clinching scenario.

The Lions would need to win and get a lot of outside help to secure a playoff spot this weekend, but it is indeed possible. Detroit is one of three teams (and the only NFC team) that can end up with a spot in the postseason based on this week’s results.

Here are the six scenarios where the Lions can clinch a playoff berth by the end of Week 13.
