Kansas City Chiefs quarterback Patrick Mahomes exited Thursday Night Football's rivalry game with the Denver Broncos at Mile High Stadium after injuring his right knee at the bottom of a pile.
The injury came after a fourth-and-1 play inside the Broncos red zone with Mahomes running a quarterback sneak. Mahomes then laid on the ground looking helpless and unable to get up.
Television cameras showed Chiefs medical staff appearing to pop Mahomes' kneecap back into place. Mahomes was then carried off the field after a long pause laying on the ground, but did eventually limp to the locker room on his own power.
Mahomes will not return to the game.
