The teams may no longer be Northern California neighbours, but the rivalry remains strong between fans of the 49ers and Raiders.
While the Raiders packed up and left Oakland for Las Vegas in 2020, there remains a fervent fan base in the Bay Area.
The Niners also are billed as representing San Francisco, but have played out in Santa Clara — roughly 85 km south and closer to San Jose — since 2014.
Those shifts in geography didn’t seem to matter much to some rival fans as the teams clashed on Sunday at Levi’s Stadium, as the opposing sides duked it out in a wild parking-lot brawl that left several men knocked unconscious.
What happened in the brawl?
Instagram user @frisco_phillyb4x posted a video showing a huge brawl in the parking lot before the game as fans of both teams clashed during tailgate festivities.
The clip, which has gone viral after being shared by several users on Instagram and X, begins with two fans squaring up and one lands a heavy shot to his rival’s jaw, knocking him out and causing him to drop to the ground with his legs bent at awkward angles.
WARNING: Violent scenes
Another fan wearing a 49ers jersey then rushes in and knocks the second fan unconscious with a haymaker of his own. A group of fans from both sides then converge, with more punches being thrown and one man viciously attacking the second man who had been knocked out as he lay on the ground.
Police sirens are heard as some fans begin to scatter and the clip comes to an end.
None of the identities of the fans involved have been revealed and there hasn’t been any update on injuries suffered by anyone involved in the incident.
The fights didn’t end there, either. The Instagram user also shared several posts of other altercations between fans inside the stadium during the game, including fights in the lower bowl and in the upper deck.
It’s unclear if police will further investigate the violent incidents.
What happened in the game?
On the field, the 49ers won the game 38-17 to improve their record to 7-1 while Vegas dropped to 4-5 and faces further questions over when the team could turn to first-overall pick Fernando Mendoza at QB.
Unfortunately for the Niners, they lost rookie defensive tackle Gracen Halton for the season due to a broken ankle suffered late in the contest.
