It was a long-time tradition between the two schools. The last game where the Bruins and Trojans did wear their home uniforms was 1982, the first year UCLA moved to the Rose Bowl, which resulted in a win for UCLA.
The NCAA then dictated that two teams couldn't wear home uniforms. It passed a rule stipulating that a visiting team does wearings its home uniforms will forfeit a first-half timeout and be penalized.
We've heard that Rick Neuheisel and USC's Pete Carroll have agreed that the home team will take a timeout at the beginning of the game to offset the timeout lost by the visiting team. The penalty will be declined.
From our sources, both Neuheisel and Carroll have vowed to have their teams where their home uniforms in the rivalry game as long as both are coaching UCLA and USC.
Also, there has been a great deal of speculation about Neuheisel possibly changing UCLA's uniforms. To date, we've heard that the uniforms will remain as they've been. There will also be no plans to wear throwback uniforms.
