November 10, 2026 – There’s an unspoken rule in sports fandom: your jersey is cotton, polyester or mesh. It is not body armor, and it is not a license to throw haymakers at strangers on a slab of asphalt.
Nobody told that to the crowd outside Levi’s Stadium on Sunday. The 49ers beat the Raiders 38-17, and the Bay Area’s old football grudge spilled out of the stands and into the parking lot.
Video Went Viral
Bystander footage spread across social media within hours. It shows groups of jersey-clad fans trading punches, with at least two people left unresponsive on the pavement while onlookers screamed and a few tried to intervene. Santa Clara police are investigating the incident, which they describe as active and ongoing.
The trouble wasn’t limited to the parking lot. After the game, 49ers lineman Keion White said he thought he saw fans fighting in the stands while play was underway.
The Police Response
Santa Clara police say the day ended with 45 ejections and 11 arrests. Seven of those arrested were cited for disorderly conduct, four were arrested for fighting in a public place, and at least one faced a drug possession charge. Police are still looking into several of the filmed brawls, so the numbers may not be final.
“Incidents of violence at large-scale events in Santa Clara will not be tolerated,” said department spokesperson Lt. Eric Lagergren. Police are asking anyone who witnessed violence to call 408-615-4700 or the anonymous tip line at 408-615-4847.
The Takeaway
This rivalry has a history. A 2018 game between these teams at Levi’s produced 32 arrests, mostly for public intoxication. Sunday’s version was uglier, and this time the damage was done by fans.
Football is supposed to be an escape, four quarters you live and die with. When the tribalism turns physical, nobody wins, not even the fans on the winning side. The 49ers took the scoreboard on Sunday. The people swinging in the parking lot took home a night in a cell or a citation.
