San Francisco 49ers and Las Vegas Raiders fans are already in mid-season form.

Friday’s preseason game between the two teams ended in the tightest possible result, with both scoring 24 points on the night. And things would get chippy between their supporters as they were seen engaging in a wild melee.

The video below shows a concerning scene, with a Niners fan using a chair to hurt a grounded Raiders supporter who was already blooded as it appears his head was busted in.

Fortunately, other fans were able to break things up, and the bloodied party later was seen throwing up signs while being held back as a group of San Francisco fans left the area.

Fight Between San Francisco 49ers & Las Vegas Raiders Fans Generated All The Buzz On Social Media

The fight drew plenty of reactions from fans on social media, as expected.

“So what exactly does throwing up gang signs accomplish?” one fan mused.

“It’s preseason 😂,” another pointed out.

“Of course show me a time the 49ers and Raiders played there wasn’t a fight don’t worry I’ll wait 😂😂,” someone else joked.

“Homeboy was trying to put dude through the concrete with that chair 😂,” another pointed out.

As for the game, it was entertaining enough, given that most of the regulars were rested. Brock Purdy was among four quarterbacks who were involved, throwing an admirable 9/12 for 96 yards and zero touchdowns, also surrendering possession with an interception.

Nathan Peterman and Carter Bradley made appearances under center for Vegas, with Gardner Minshew, recently named QB1, a no-show.
