A 48-45 USC win over UCLA at the Rose Bowl in the waning hours of Saturday evening clinched one of two spots in the Pac-12 Championship Game.

One year removed from a 4-8 record, USC is headed to Las Vegas as one of two confirmed participants in the Pac-12 title game. UCLA was eliminated from contention with its third conference loss in the last five games. Three teams are left alive in the race for the other spot as we approach the final week of the regular season — Oregon, Utah, and Washington

Here are the paths for each to reach the title game, according to longtime Pac-12 insider John Canzano:

Oregon makes the title game IF…

  • the Ducks beat Oregon State (12:30 p.m. PT, ABC)
  • the Ducks lose to Oregon State AND Washington State beats Washington (7:30 p.m. PT, ESPN)

Washington makes the title game IF…

  • the Huskies beat Washington State AND Oregon State beats Oregon AND Cal beats UCLA (1:30 p.m. PT, FOX; Friday)
  • the Huskies beat Washington State AND Oregon State beats Oregon AND UCLA beats Cal AND Colorado beats Utah (1 p.m. PT, Pac-12 Network)

Utah makes the title game IF…

  • the Utes beat Colorado AND Oregon State beats Oregon AND Washington beats Washington State AND UCLA beats Cal

According to Canzano, such a sequence of results would create a three-team tie between Washington, Utah, and Oregon and trigger the fourth tiebreaker in the Pac-12’s protocol, which involves the combined winning percentage in conference games of conference opponents. This scenario would give the Utes the edge.

The Pac-12 Championship Game will be played on Friday, Dec. 2 at Allegiant Stadium in Las Vegas. Kickoff has been set for a 5 p.m. PT kickoff on FOX.
