The Baltimore Ravens (13-4) entered the final week having already clinched the AFC North, the top seed in the AFC and a first-round bye. The Ravens elected to rest Lamar Jackson and other starters during a 17-10 loss to the Pittsburgh Steelers and finished the regular season at 13-4.

The Kansas City Chiefs (10-6) enter their final regular-season game against the Los Angeles Chargers having secured the AFC West division title.

The Cleveland Browns (11-6) had already locked up just their second playoff berth since 2002 before their 31-14 loss to the Cincinnati Bengals in Week 18.

The Pittsburgh Steelers (10-7), after staying alive Saturday with a 17-10 win over the shorthanded Baltimore Ravens, clinched a playoff berth when the Jacksonville Jaguars lost 28-20 to the Tennessee Titans on Sunday. The Jaguars (9-8) needed a victory to win the AFC South and make the playoffs.

With the Jaguars' loss, the Houston Texans (10-7) became the AFC South champs. The Texans defeated the Indianapolis Colts 23-19 on Saturday to clinch a playoff berth, becoming the first team since 2012 to do so with a rookie quarterback (C.J. Stroud) and rookie head coach (DeMeco Ryans).

The Miami Dolphins (11-5) and Buffalo Bills (10-6) have each clinched a playoff spot, but the winner of their matchup on Sunday Night Football will win the AFC East to take the No. 2 seed. A win or tie would give the Dolphins their first division title since 2008. The Bills, who have won the last three division titles, locked up a playoff spot Sunday with the Jaguars' loss to the Titans.
