Mahomes would not re-enter the game, giving way to backup quarterback Chad Henne for the Chiefs final drive.

According to ESPN, Mahomes had cleared concussion protocol and was available to get back on the field, but the team decided against it with the game already out of reach.

The Chiefs went on to lose 27-3. It was the first time the Chiefs failed to score a touchdown in a game since their loss to the Tampa Bay Buccaneers in Super Bowl LV.
