The Bills won't have cornerback Taron Johnson to help them try to slow down the Chiefs offense on Sunday afternoon.

Cam Lewis and Ja'Marcus Ingram are expected to handle nickel duties against Patrick Mahomes and the Chiefs, while Buffalo gets some good news with Terrel Bernard and Matt Milano returning.

Bills nickel corner Taron Johnson is questionable for Sunday's game against the Chiefs, while coach Sean McDermott says safety Taylor Rapp is "probably" done for the season after going on injured reserve with a knee injury.

Johnson first appeared on Buffalo's injury report Friday with a groin injury. He entered the weekend deemed questionable to suit up Sunday but ultimately isn't going to be able to play. Cam Lewis is set to start in the slot in Johnson's stead.

The latest iteration of AFC armageddon takes place Sunday afternoon at Highmark Stadium when the 5-2 Bills host the 5-3 Chiefs in a game that, as always, figures to have huge ramifications down the line when it comes to deciding division races and conference playoff seeding.

Buffalo ranks ninth in points allowed (20.9), but do a great job of pressuring and suppressing quarterbacks, allowing just 161.9 passing yards per game. They are a team that can be run on, though, allowing 5.5 yards per rush and 150.3 per game, which both rank 31st in the NFL.

Johnson (groin) is listed as questionable ahead of Sunday's matchup against the Chiefs.
