Chiefs vs. Bills NFL scores, live updates: Kansas City heads to Buffalo as top 2 AFC teams face off

Roger Staubach vs. Terry Bradshaw. Steve Young vs. Troy Aikman. Tom Brady vs. Peyton Manning.

Those quarterback matchups defined decades in the NFL, and for the eighth time in the past five seasons, Patrick Mahomes and Josh Allen will face off with the entire NFL world watching. The stakes couldn’t be higher, either — at least for a regular-season game.

The Chiefs enter the matchup as the league’s only remaining unbeaten team at 9-0, having found just about every possible way to win a game this season, while the 8-2 Bills have a giant lead in the AFC East and have ripped off five straight wins, scoring 30-plus points in the past four games.

Kansas City holds a 4-3 lead over Buffalo in the seven Mahomes-Allen matchups. The Bills have actually beaten the Chiefs each of the past three years in the regular season, but in January of 2021, 2022 and 2024, Kansas City knocked Buffalo out of the playoffs, including in Orchard Park on their way to a second straight Super Bowl title last season.

The Chiefs-Bills matchup gets its own marquee spot this Sunday — a 4:25 p.m. ET national start time on CBS. Fox will show either Falcons-Broncos or Seahawks-49ers, which are both set for 4:05 p.m. ET kickoffs to round out the afternoon slate.
