Kansas City Chiefs starting right tackle Mitchell Schwartz ruled out vs. Buffalo Bills with back injury
Schwartz, 31, started the game after being listed as questionable to play on the final injury report of the week.
Starting left guard Mike Remmers moved to right tackle after Schwartz left the lineup. Remmers was replaced by Nick Allegretti.
Until last season, Schwartz hadn’t missed a snap since arriving in the NFL in 2012 with the Cleveland Browns. He left the Chiefs’ lineup last year for a handful of snaps during a game against the Tennessee Titans.
The Chiefs also lost backup defensive end Alex Okafor during the Bills game with a hamstring injury.
