During the Buffalo Bills vs Kansas City Chiefs rivalry game, tensions were running high. To make matters worse, a big fight erupted between the two teams on Sunday.

It was five minutes into the second quarter when the Bills were leading 13-7 that a fight broke out. It is not clear what caused the fight, but Chiefs guard Trey Smith pushed Bills linebacker Dorian Williams into JuJu Smith-Schuster.

As the three players fell to the ground, other Bills players, like A.J.Epenesa, tried to separate Smith from their teammate by throwing punches. Eventually, the referees stepped in and both Smith and Epenesa were given penalties for their actions.
