Bills: The Buffalo Bills were off in Week 12, so they didn’t move in our rankings. They are still the clear No. 2 team in the AFC, and you can make an argument that they are No. 1 after beating the Chiefs in Week 11.

The Buffalo Bills had a week off to rest after their victory over the Kansas City Chiefs in Week 11. The bye week came at a great time for Buffalo, riding high after that victory over the Chiefs pushed their win streak to six games.

Even after a week off, the Bills are still considered the second-best team in the NFL, at least according to this week's power rankings.

It’s Week 13 in the NFL, and the Buffalo Bills are preparing to host the San Francisco 49ers on Sunday Night Football at 8:20 p.m. Buffalo (9-2) enters the contest having won six straight and is coming off a bye week. Meanwhile, San Francisco (5-6) has dropped two straight and three of five as injuries continue to pile up.

There is a high Risk of Weather Impact (ROWI) for the NFL's Sunday Night Football matchup between the 49ers (5-6) and the Bills (9-2) in Buffalo.

Buffalo Bills face the injury-plagued San Francisco 49ers at home. With potential snow showers and strong winds, the game's outcome remains uncertain.
