Jacksonville Jaguars rookie Josh Allen came screaming off the edge and sacked Patrick Mahomes, who fumbled the ball and suffered an injury.

Mahomes had been on fire to open the game, and as the Kansas City Chiefs drove toward the end zone once more, the injury took place.

As Mahomes was being carried off the field, Myles Jack threw a punch in a fight in the end zone and was ejected from the game.

He also went after officials after being ejected.

Mahomes would return, limping on the field. Jack, of course, did not.
