In a thrilling showdown, the Kansas City Chiefs defeated the Buffalo Bills 84-66 in Week 12 of the 2026 season, solidifying their position in the playoff race. Both teams showcased explosive offenses, but it was Kansas City's firepower that ultimately prevailed in this high-scoring affair. Patrick Mahomes was outstanding for the Chiefs, throwing for six touchdowns while racking up significant yardage. However, it was Kenneth Walker's impressive 255 rushing yards and Xavier Worthy's jaw-dropping 389 receiving yards that truly highlighted Kansas City's offensive dominance. The Chiefs’ ability to stretch the field and find the end zone consistently kept the pressure on the Bills. Defensively, L'Jarius Sneed's two interceptions were crucial in stifling Buffalo's attempts at a comeback, while Kaleb Elarms-Orr of the Bills made a strong impact with seven tackles and three sacks. The turning point came when Sneed picked off Allen in the third quarter, giving the Chiefs a critical opportunity to extend their lead. Kansas City’s defense, although not flawless, managed to make the necessary plays when it mattered most, allowing them to secure the victory.
