Eugene, Ore. • Jordan Williamson hit a 37-yard field goal in overtime to help No. 14 Stanford upset No. 1 Oregon 17-14, denying the Ducks a chance to clinch the Pac-12 North and derailing their straight shot at the BCS championship game.
If both Stanford and Oregon finish with wins in their final games next weekend, both will finish with one conference loss, which means Stanford will win the head-to-head matchup and go to the Pac-12 championship game for a chance to play in the Rose Bowl.
Stanford (9-2, 7-1) will visit No. 17 UCLA, which defeated No. 21 USC 32-29 earlier in the day to claim the Pac-12 South. Oregon (10-1, 7-1) will play rival Oregon State in the annual Civil War rivalry game in Corvallis.
The loss snapped a 13-game winning streak for the Ducks, which was the longest current streak in the nation. It was Stanford's fifth straight win.
Oregon was the only Pac-12 team that Stanford hadn't defeated over the past two seasons.
