Raiders Fan Socked In Face In Violent Fistfight At Chargers Game

A Las Vegas Raiders fan had a really rough Sunday afternoon in Los Angeles ... his team not only lost to the Chargers -- he was socked in the face by a huge haymaker while attending the game.

The Howie Long supporter was decked after he got into a spat with a Justin Herbert fan during the Raiders vs. Bolts tilt at SoFi Stadium ... and the wild fight was all captured on video.

You can see the fracas appeared to start when the Long supporter got into the face of the man in the powder blue jersey.

Apparently not liking the guy in his grill, the Herbert supporter got up and seemed to headbutt the Long fan ... before uncorking a massive right hand that caught the guy flush in the face.

The blow sent the Raiders fan straight to the ground ... but when he got up, he was hit by another couple punches. Eventually, the Herbert fan pushed the guy down several rows of stairs.

Thankfully, a man in a black Charles Woodson jersey stepped in to break up the fight before things escalated further.

It's unclear if either combatant was kicked out of the game over the melee.
