However, if the Steelers lose and the Chargers win, Los Angeles would advance to No. 5 in the AFC playoffs and the Steelers would drop to No. 6.

In that case, the Steelers would travel to Baltimore to face the Ravens for the third time this season. The Steelers and Ravens split their two regular season meetings, with the Steelers winning 18-16 in Pittsburgh and the Ravens winning 34-17 in Baltimore in Week 16.

Two-time defending champion Kansas City (15-1) secured the No. 1 seed with its win over the Steelers on Christmas Day.

Buffalo (14-3) secured the No. 2 seed with its win over the New York Jets on Sunday.

Houston is seeded No. 4, while the seventh spot remains open between the Bengals (8-8), Dolphins (8-8) and Broncos (9-7).

If the Broncos win against Kansas City in Week 18, Denver will clinch the final playoff spot in the AFC. If Denver loses and Miami and Cincinnati both win, Miami will secure the final spot.

Cincinnati can only secure the No. 7 seed in the playoffs with a win over the Steelers and a loss against the Broncos and a loss or tie against Miami.

The Dolphins end the regular season against the Jets in New York.
