A violent altercation broke out between fans in the stands at Arrowhead Stadium. In a video that quickly went viral, a Broncos fan can be seen confronting two Chiefs fans, who pushed him across several rows of seats before pinning him in a headlock. The fight continued despite security's efforts to calm the situation, and what followed was even more chaos when another Denver fan punched a security guard who was trying to restore order.
