Angry fans in Buffalo turn on each other as fists fly in the stands of Highmark Stadium... as the Bills lose to the Broncos on a walk-off field goal

Frustration boiled over in 'the City of Good Neighbors' as Buffalo Bills fans were seen fighting each other in the stands.

On a night that Buffalo ended up losing the game on a walk-off field goal to the Denver Broncos, the lack of good performance on the field led to Bills Mafia looking more like a mob in the seats of Highmark Stadium.

One video captures a man in a white hoodie and a Josh Allen jersey taking on multiple fans at once.

That fan landed some good shots on a man in a white jacket but appeared to catch a right hand from a man in a brown plaid shirt.

Judging by the fact that the speakers were playing the Bills' edited version of The Isley Brothers classic 'Shout' - this fight occurred sometime after Buffalo scored some points.

This is just the latest in a string of incidents that have marred this NFL season - as fan violence appears to be getting worse.

Earlier this year, a New England Patriots fan got into an altercation with a fan of the Miami Dolphins. The Pats fan ended up passing away due to his injuries.

Other fights have been sighted at AT&T Stadium in Dallas, SoFi Stadium in Los Angeles, and MetLife Stadium in the New Jersey Meadowlands.

SoFi Stadium in particular has seen plenty of violence - with multiple reported fights during a game between the Chargers and the Raiders. Weeks later, Chargers fans were brawling with Cowboys fans as well.

The NFL has not yet announced a plan to separate rival fans from each other. But with incidents like tonight, such a plan wouldn't be useful.

Additionally, ticket re-sale culture in the United States would essentially make it impossible to ensure that rival fans would separate from each other.

Buffalo went into the final moments of the game leading 22-21 over Denver and fans thought they won the game when a Broncos field goal went wide right.

However, referees found that there were 12 men on the field, leading to a re-kick that Denver's Will Lutz knocked through with ease.
