The San Francisco 49ers secured a decisive 27-16 victory over the Kansas City Chiefs in Week 16 of the 2026 season, solidifying their playoff positioning with the win. The stakes were high as both teams aimed to boost their chances heading into the postseason, but it was the 49ers who came out on top. Patrick Mahomes led the Chiefs' offense with a solid performance, throwing for 244 yards and one touchdown, but it was Christian McCaffrey who stole the show on the ground for San Francisco, rushing for 99 yards. Tight end George Kittle also made a significant impact, racking up 85 receiving yards and contributing to the 49ers' offensive success. Defensively, the 49ers were able to apply pressure, with Alfred Collins recording a key sack that disrupted the Chiefs' rhythm. Kansas City’s Alohi Gilman led the team with seven tackles, but the 49ers' ability to make crucial stops and contain the Chiefs' explosive plays proved to be a turning point in the game, allowing San Francisco to control the pace and secure the win.
