There was plenty of action on the field during the Chargers vs. Raiders game Sunday — but there was even more of it off the gridiron … with fans from both teams getting in violent brawls throughout the afternoon.

One of the bigger ones happened just outside of SoFi Stadium near one of the parking lots … when a fan in a Divine Deablo jersey got thrown to the ground by a Chargers supporter rocking some Derwin James threads.

You can see in video captured by a bystander, a Maxx Crosby fan tried to step in to break things up … but he was quickly hit in the face by not just the Raiders fan — but a woman too.

The woman in the fracas then got re-involved in the mix — pulling the Crosby fan off the pile, and after a few more moments of scuffling, the Crosby supporter then body slammed her to the ground before leaving the area.

Inside the stadium, meanwhile, two Raider fans got into it with a couple Chargers backers in the seats — leading to a flurry of punches being thrown between the men.

The fans were seemingly inspired by the action on the field, as players between the two squads got into a spat late in Sunday’s contest … with Chargers receiver Joshua Palmer and Raiders cornerback Jack Jones both ejected for their roles in the tussle.
