The stage is set for Levi's Stadium in Santa Clara - the battle between the Pac-12's North and South will double as a battle between California's north and south.

By virtue of their commanding 40-21 victory in the Crosstown Showdown, the USC Trojans clinched the Pac-12 South division title Saturday, setting up a Pac-12 Football Championship Game match-up between the Trojans and the Stanford Cardinal on Dec. 5.

No. 22 UCLA

The Bruins survived their initial test last week, staving off elimination from the Pac-12 South race with a road win over Utah. But they couldn't get it done against their crosstown rivals in their final regular season game, keeping them from a 3rd Pac-12 South title and a trip to Santa Clara. The Bruins now wait to see where they're headed for the postseason.
