Warning: Video contains violence

A Panthers fan took his aggression too far Thursday night during the team’s 28-23 loss to the Eagles, sucker-punching another fan in the stands.

According to an onlooker, who posted the assault on Instagram, an older fan asked the Panthers fan and his girlfriend to sit down, as they had been standing during the game. As words were continually exchanged, the Panthers loyalist allegedly called the victim a “geriatric f–k” before throwing a punch. Others surrounding the exchange tried to keep the aggressor from doing more damage.

As the enraged Carolina twosome left the scene of the incident to an eruption of boos and shouts, the older fan stayed seated as blood dripped down his face.

The Panthers released a statement Friday, confirming they identified the person in question.

“We have reviewed video tape of the incident and have identified the perpetrator. We are working with the Charlotte Mecklenburg Police Department to pursue charges to the fullest extent of the law,” the statement read.

“The Carolina Panthers are committed to a fan-friendly and family-friendly stadium experience. The behavior exhibited by the perpetrator is unacceptable and will not be condoned at Bank of America Stadium.”

Carolina’s next home game will take place on Sunday, Nov. 5 against the Atlanta Falcons.
