In the NFC, three division leaders -- Atlanta (12-2), San Francisco (10-3-1) and Green Bay (10-4) -- have clinched playoff spots.
Seattle (9-5) is the wild-card leader.
The Vikings (8-6) would nab a wild-card berth and the sixth seed if the playoffs started this week, but the Vikings still wouldn't necessarily qualify for the playoffs if they win out.
Washington, Dallas and the N.Y Giants are all 8-6 and battling for the NFC East title.
• Washington and Dallas play each other in Week 17, so either team would claim the East title by winning out.
• The Giants can earn at least a wild-card spot by winning out. If the Vikings and the Giants both go 10-6, the Giants would win the tiebreaker (better record in conference games).
• If the Vikings and Chicago both go 10-6, the Vikings would win the tiebreaker (better division record).
• If Seattle and the Vikings both go 10-6, the Seahawks win the tiebreaker (victory in head-to-head meeting).
Losing Sunday at Houston wouldn't necessarily eliminate the Vikings from a playoff spot. If they beat Green Bay in Week 17, they still could make the playoffs if the Bears finish 9-7 and both the Giants and Cowboys lost in Week 17, changing the tiebreakers.
