The NFL is in contact with Carolina Panthers security after a video surfaced from Thursday night's game showing a fan in a Panthers jersey punching another fan in the face several times in the upper deck of Bank of America Stadium during a game against the Eagles.

You can see the video here but be warned, it's graphic.

According to Instagram user odubco, who posted the video, the man in the Panthers jersey and the woman with him were standing during the game, the fan behind him "took offense to the couple never sitting down and obstructing his view" and it escalated from there.

After throwing several punches and leaving the fan bloodied, the man and woman quickly left their seats.

"We take all of these very seriously," the league said of the incident, according to NFL.com's Ian Rapoport.
