SEATTLE -- The Washington Huskies remain No. 4 in both major college polls while the Washington State Cougars broke into the rankings at No. 25 Sunday.

Both teams remain on a collision course for what may be the most consequential Apple Cup ever when they meet for the 109th time.

The Huskies (5-0 Pac-12, 8-0 overall) survived a 31-24 win over Utah while the Cougars (5-0, 6-2) came back from a 24-6 halftime deficit to beat Oregon State 35-31 Saturday night.

The wins virtually guarantee one of the two Evergreen State teams will represent the north in the Pac-12 Championship Game on Dec. 2. The next closest team is Stanford (3-3, 5-3), which both the Dawgs and Cougs have beaten head-to-head.

Washington faces Cal (2-3, 4-4) next week. A Huskies' victory would eliminate Cal and Stanford from the race. The Cougars visit Arizona (0-5, 2-6).

The Huskies remain on track for a shot at the national championship as long as they keep winning. The first official College Football Playoff rankings come out Tuesday, but multiple bowl projection polls have them playing in the national semifinals.

The best the Cougars can hope for is a Rose Bowl berth, but they may have to win the Pac-12 title to make that happen, which means going through the Huskies for the north title.

And that may be decided in Pullman the day after Thanksgiving.
