It was unnecessary roughness of epic proportions between Chicago Bears fans on Sunday. 

Another NFL weekend led to off-the-field violence during the Bears’ loss to the Minnesota Vikings.

Violence in the stands has become an ongoing issue at NFL stadiums since the season began and the latest example allegedly occurred over the bathroom, according to the X user who posted it. 

The clip, which has been viewed over 140,000 times since it was posted on Sunday, shows a fan in a Justin Fields jersey mixing it up with another fan and then appears to show him blindside a man wearing a Walter Payton jersey with a right hook. 

The punch appeared to connect with the other fan’s head and he went down to the ground instantaneously. 

The man in the Fields jersey then turns his attention to another group that was scrapping, though it’s not entirely clear if the combatants had known one another. 

Fighting at NFL games – or at any pro sporting events – is nothing new, but the problem has seemed to be a weekly occurrence across football stadiums this season. 

One of the deadliest incidents came when Dale Mooney, 53, died following a Sept. 17 altercation at a Miami Dolphins game against the New England Patriots at Gillette Stadium.

An autopsy concluded that “medical conditions” that Mooney had may have contributed to his death, according to CBS News Boston. 

Foxboro police announced last week that they were seeking criminal complaints against three Rhode Island men, which allege assault and battery and disorderly conduct in connection with Mooney’s death. 

A recent Sportsbook Review survey indicated that nearly 40 percent of football fans said that they had witnessed a crime at or around an NFL stadium. 

In a statement to the Daily Mail, the NFL called the safety of fans its top priority. 

“Our top priority is the safety of the more than one million fans who attend games each week. We deplore the activities of a handful of fans who interfere with the enjoyment of others,” the statement said.
