AFC Bracket
Bye: No. 1 Kansas City Chiefs
No. 7 Buffalo Bills at No. 2 New England Patriots
No. 6 Los Angeles Chargers at No. 3 Tennessee Titans
No. 5 Indianapolis Colts at No. 4 Cincinnati Bengals
Thanks to the Colts' victory over the Patriots on Saturday, Patrick Mahomes and the Chiefs leaped into the No. 1 spot in the AFC. Since the NFL expanded to seven playoff teams in each league last year, that first-round bye is especially coveted now.
That result in Indy affected three more teams. New England dipped below Kansas City for the No. 2 seed, while Indianapolis rose to No. 5 and traded places with the Chargers—who fell to No. 6.
Cincinnati's win at Denver combined with Baltimore's loss to Green Bay swapped the AFC North lead. Cincinnati owns a head-to-head victory over the Ravens, so losing that tiebreaker means Baltimore is suddenly on the outside of the picture.
NFC Bracket
Bye: No. 1 Green Bay Packers
No. 7 Washington at No. 2 Tampa Bay Buccaneers
No. 6 San Francisco 49ers at No. 3 Dallas Cowboys
No. 5 Los Angeles Rams at No. 4 Arizona Cardinals
Arizona provided the stunner of Week 15, wasting a favorable matchup and losing 30-12 to the Detroit Lions. The loss also dropped the Cardinals from No. 3 to No. 4, which the Cowboys held before defeating the New York Giants 21-6.
Heading into Sunday night's clash in Tampa, no other seeding has changed in the NFC over the weekend.
