The 2012 college football schedule features Pac-12 conference battles in Week 4. All but two of the teams are in action against conference foes as the race for division titles and bids to the Pac-12 championship game heat up.

The UCLA Bruins look to continue their hot start as they host the Oregon State Beavers in their Pac-12 opener on Saturday. The Bruins are 3-0 after blowout victories over Houston and Rice, to go along with a signature non-conference win over the Nebraska Cornhuskers. The Beavers have played just one game this season, an upset victory at home over the Wisconsin Badgers.

USC began their conference slate last week on a sour note when they fell to the Stanford Cardinal on the road. They will look to rebound on Saturday as they face the California Golden Bears at home. Cal is 1-2 on the season, but nearly defeated Ohio State on the road in Week 3.

Here is the complete Pac-12 schedule for Week 4 (all times Pacific):

Oregon St. at UCLA, 12:30 p.m. (ABC/ESPN2)

Colorado at Washington St., 1 p.m. (FX)

California at USC, 3 p.m. (PAC-12 NETWORKS)
