Five people were hurt when thousands of fans poured on to the field at the Coliseum to celebrate USC's 20-17 upset victory over Stanford Saturday, KNBC-TV, Los Angeles, reported.
"They normally control it so people don't get onto the field, but this time I think there was just so much excitement they let the people go," USC fan Joe Sullivan told KNBC-TV.
Five other fan injuries were reported during the game, but details were not available.
The fire department said injuries on the field included one person who fell and another with a broken ankle. All of the injuries were considered non-life-threatening.
