Bills Defeat Chiefs 28-21; Mahomes Struggles

The Buffalo Bills defeated the Kansas City Chiefs 28-21 at Highmark Stadium, improving to 6-2 while Kansas City fell to 5-4 and third in the AFC West. Patrick Mahomes had the worst completion percentage of his career (15-of-34, 44.1%) for 250 yards, no touchdowns, one interception and took three sacks, snapping his touchdown streak. Josh Allen was near-perfect (23-of-26, 273 yards) and Buffalo got big contributions from James Cook and Dalton Kincaid as the Bills dominated complementary phases. The loss highlighted Kansas City's 0-4 mark in one-score games and concerns about consistency. The Chiefs have a bye week before a key Week 11 trip to Denver to regroup.
