Chiefs quarterback Patrick Mahomes was injured on a touchdown throw in the fourth quarter.

Mahomes rolled to his right on the third goal and something in his leg appeared to give way on a non-contact play. He fired the ball over the top from Lavonte David to running back Samaje Perine for a 7-yard touchdown with 14:14 remaining.

Mahomes remained on the field and needed help getting to the sideline.

He entered the team’s medical tent before heading outside to jog along the sideline. The crowd at Arrowhead Stadium erupted.

Carson Wentz was warming up, but Mahomes has since started throwing on the sideline.

ESPN sideline reporter Lisa Salters reported that Mahomes has an ankle injury but will return.

The teams are tied 17-17.
