What time is the USC-UCLA football game?

Saturday’s renewal of the USC-UCLA rivalry won’t be decided until late at night. The game at the Rose Bowl will kick off at 7:30 p.m.

The start time means Fox passed on the game as its first choice among Pac-12 matchups.

The network chose instead to air Washington State’s trip to Colorado at 12:30 p.m., a game that USC fans will watch with interest — the Trojans still need a win on Saturday and losses by Colorado and Utah to claim the Pac-12 South Division title.

ESPN, which selected games second, picked up the game at the Rose Bowl.

The game will be the fifth time that UCLA has kicked off at 7 p.m. or later. USC has played only one such game, a Thursday-night affair against California.

The last time this rivalry game started in the late time slot at the Rose Bowl, in 2010, a pregame drunken brawl sent two men to the hospital with stab wounds and three people to jail. About 50 to 75 people were involved in the melee.
