The Philadelphia Eagles improved to 5-1 on the season last night with a 28-23 road win over Cam Newton and the Carolina Panthers, putting the Eagles atop the NFC standings. 

During the second half of last night's game, a Panthers fan was sucker punched in the face and left bloody... but it wasn't an Eagles fan who did the damage. As it turns out, both parties involved were rooting for the Panthers, but shit got real when the victim told the attacker and his girlfriend to sit down and stop obstructing his view.

Here's an account of what went down, according to a fan who witnessed and videotaped the attack,

"dude bro & his chicka were standing for the entire game. words gradually got more and more escalated. there previously was a single mom and her son between us, they left halfway through the 3rd. after that, the lid was off. the dude took offense to the couple never sitting down and obstructing his view. the victim telling the dude bro how they’re being jerks and how rude they are for not sitting. the dude bro turns around and calls the victim a “geriatric fuck”, “faggot”, and “hick”. then sucker punches him right in the face. i don’t know if he got away or left in handcuffs, but i hope it’s the latter."

According to the NFL Network's Ian Rapoport, the NFL is investigating the assault.
