SANTA CLARA, Calif. >> Patrick Mahomes overcame two interceptions to deliver a few big plays with his feet and the Kansas City Chiefs remained the league’s only undefeated team, beating the San Francisco 49ers 28-18 Sunday in a Super Bowl rematch.

The stakes weren’t the same as eight months ago when Mahomes and the Chiefs (6-0) beat the 49ers (3-4) 25-22 in overtime for their Super Bowl title in five seasons.

The game came with a potentially heavy price for San Francisco with star receiver Brandon Aiyuk getting carted off after getting hit on his right knee while making a catch late in the first half. Aiyuk’s absence proved crucial during a key point late in the third quarter when the 49ers were intercepted.

The Chiefs then turned that into a touchdown thanks in part to a 33-yard scramble by Mahomes that was his longest regular-season run ever.

Mahomes then scored on a 1-yard scramble on fourth-and-goal for his first rushing touchdown since the 2022 season.
