Patrick Mahomes Posts Career-Low Completion Rate as Chiefs Fall 28-21 to Bills

Patrick Mahomes and the Kansas City Chiefs suffered a 28-21 defeat to the Buffalo Bills, marking one of the most challenging performances of Mahomes' nine-year career, with a completion rate below 50% for the first time. Mahomes completed 15 of 34 passes for 250 yards, with one interception and no touchdowns, while facing intense pressure from the Bills' defense that sacked him three times and hit him 15 times. The Chiefs briefly led early in the game but struggled to sustain drives, and their final comeback attempt was ended by a crucial interception from rookie Maxwell Hairston. This loss dropped the Chiefs to a 5-4 record, placing them outside the AFC playoff picture heading into their bye week and trailing AFC West leader Denver by two games. Despite recent success against Buffalo in the playoffs, Mahomes emphasized the need for greater consistency and battle readiness moving forward. Buffalo quarterback Josh Allen outperformed Mahomes with a record 88% completion rate and three touchdowns, underscoring the Bills' dominance in this matchup.
