A Super Bowl rematch showed how the Chiefs keep rolling despite losing their explosiveness in a Week 7 that included another ugly loss for the Jets after a big trade.

The 49ers were without three of their top playmakers for much of the matchup, with running back Christian McCaffrey (Achilles) and wide receivers Brandon Aiyuk (knee) and Deebo Samuel (illness) all sidelined by the end of the day. Their final touchdown, a sneak by Purdy, came with under two minutes to play.

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 after beating the San Francisco 49ers 28-18 in a Super Bowl rematch.
