Dramatic footage has emerged of a punchup between fans during an NFL game in the US.

The video, captured during Saturday's game between Tennessee Titans and New York Jets, shows the fans trading punches after one of them allegedly took the other's phone.

Other fans then rush in to break up the pair.

According to the filmer, the man with the Batman shirt was later put in handcuffs and led away.

Titanup is the nose bleed
Batman is the other guy.

So titanup took batman phone, batman was trying to get his phone back, but titanup had told him he'll give it back when he wants to. So batman continues, that's when titanup pushed batman and batman punched him. So batman was in handcuffs until I showed the officers the video that's when batman was asked if he wanted to press charges on titanup since he caused the assault first. Basically all this happened because he was just trying to get his phone back
