Here's a quick look at Week 13 in the conference. All times are ET.
Utah (4-7, 2-6) at Colorado (1-10, 1-7) 3 p.m. FX: Colorado leads the series 31-24-3, including a 17-14 upset victory in 2011, which prevented the Utes from winning the Pac-12 South Division title. Both teams have had disappointing seasons. Utah won't play in a a bowl game for the first time since 2002. And Colorado has posted probably the worst season in school history.
No. 25 Washington (7-4, 5-3) at Washington State (2-9, 0-8) 3:30 p.m. FOX: Washington leads the rivalry series 67-31-6 and has won three in a row, including a 38-21 win last year. The Huskies are hoping for their first eight-win season since 2001. The Cougars are hoping to avoid their second winless conference campaign since 2009. It will be interesting to see how the Huskies' rejuvenated defense does on the road against Mike Leach. The Huskies are 16th in the nation in pass efficiency defense after ranking 87th in 2011.
Arizona State (6-5, 4-4) at No. 24 Arizona (7-4, 4-4) 10 p.m. ESPN: Arizona leads the rivalry series 47-37-1 and has won three of four, including a 31-27 upset in Tempe last year. First year coaches Todd Graham and Rich Rodriguez know each other fairly well, they've coached against each other before and Graham was on Rodriguez's staff at West Virginia in 2001 and 2002. Arizona RB Ka'Deem Carey leads the nation with 144 yards rushing per game. The Wildcats have never had a back win the national rushing title. Arizona QB Matt Scott will need to keep an eye on ASU DE Will Sutton, who's fifth in the nation with 1.05 sacks per game.
No. 5 Oregon (10-1, 7-1) at No. 15 Oregon State (8-2, 6-2) 3 p.m. Pac-12 Network: Oregon leads the rivalry series 59-46-10 and has won four in a row, including a 49-21 win last year. Another good defense to test Oregon after Stanford won the battle against the Ducks last week. The Beavers are 14th in the nation in run defense and 21st in scoring defense (18.6 points per game). Oregon QB Marcus Mariota fell from first to sixth in the nation in passing efficiency after the Stanford loss. Both teams rank in the nation's top 10 in turnover margin. The Ducks are second in the nation in interceptions. Sean Mannion, who threw for 325 yards and four touchdowns in the win over California last weekend, will start at quarterback. He previously lost his job after throwing four interceptions against Washington.
No. 8 Stanford (9-2, 7-1) at No. 17 UCLA (9-2, 6-2) 6:30 p.m. FOX: UCLA leads the series 45-34-2, but it has lost three in a row to Stanford, including a 45-19 loss last year. The Bruins already have won the Pac-12 South Division and will play in the Pac-12 title game on Nov. 30. If they beat Stanford, they will play at Oregon, if the Ducks beat Oregon State. The Bruins will play at Stanford if they lose to the Cardinal (yes a second game within six days), or they will play host to Stanford if they beat the Cardinal and Oregon State beats Oregon. This will be another test for the Cardinal defense, which is fresh off shutting down Oregon in a 17-14 overtime win. UCLA ranks 16th in the nation in total offense and 20th in scoring.
No. 1 Notre Dame (11-0) at USC (7-4, 5-4) 8 p.m. ABC: Notre Dame leads the series 43-35-5, but USC has won nine of 10, including a 31-17 win in South Bend a year ago. If Notre Dame wins, it will play for the national title, likely against the SEC champion. If USC wins, it will keep Oregon's hopes alive for getting into the national title game. USC QB Matt Barkley won't play after he suffered a sprained shoulder late in the loss to UCLA. He will be replaced by redshirt freshman Max Wittek, the favorite to win the starting job next fall. Wittek will face a defense that is ranked No. 1 in the nation in scoring defense and sixth in total defense.
