A violent altercation involving around 10 individuals unfolded in a burger restaurant in California, resulting in two people sustaining stab wounds, as reported by local law enforcement, per Yahoo! News.

The incident, captured on video, depicts individuals donning jerseys representing the San Francisco 49ers and the Las Vegas Raiders engaging in a brawl inside the Santa Clara In-N-Out Burger.

The altercation occurred following a pre-season football match between the San Francisco 49ers and Los Angeles Chargers at the nearby Levi's Stadium.

The storied rivalry between the Raiders and the 49ers, bolstered by their history as former Oakland and San Francisco teams, is well-known in the sports world.

Although both teams had previously faced off earlier in the summer, tensions still simmered.

Responding to a reported altercation within the fast-food eatery at approximately 11:12 pm on August 25, the Santa Clara Police Department disclosed that officers detained multiple individuals at the scene.

Two victims with multiple stab wounds were identified and promptly taken to a medical facility for treatment.

As the search for the alleged assailant continues, the police have yet to release information regarding the condition of the injured individuals.
