Close to 40 people were involved in the brawl before Saturday's USC-UCLA football game.
At one point, you can see an officer using what looks like pepper spray.
Pasadena police received a call about 4:20 p.m. about a fight in Parking Lot 1 where USC and UCLA fans were tailgating before the game began.
During an investigation, they found two men with stab wounds, who were said to be in fair condition after being treated at a local hospital.
During the fight, 24-year-old Vimal Patel was stabbed in the back, and 27-year-old Joshua Dirling was stabbed in the face.
Two officers suffered minor injuries.
Three people were arrested, one on attempted murder charges.
