The Kansas City Chiefs secured a decisive 30-8 victory over the Buffalo Bills in Week 12 of the 2026 season, maintaining their position in the playoff race. With both teams vying for critical momentum as the season approaches its final stretch, the Chiefs showcased their dominance on both sides of the ball. Patrick Mahomes led the Chiefs' passing attack with 164 yards, but it was RJ Harvey’s remarkable performance on the ground that stole the show, racking up 181 rushing yards. Tua Tagovailoa managed to find the end zone for the Bills with a single touchdown pass, but the offense struggled to keep pace with Kansas City's explosive plays. Defensively, the Chiefs were a formidable force, highlighted by Dexter Lawrence II's four sacks that disrupted the Bills' rhythm throughout the contest. The game's turning point came when Marshon Lattimore intercepted Tagovailoa, stifling a potential scoring drive and shifting momentum firmly in Kansas City's favor. The Chiefs' defensive prowess ultimately sealed the victory, limiting Buffalo to just eight points.
