With a trip to the Pac-12 title game at stake, No. 9 Oregon had an all-time collapse at the hands of rival No. 21 Oregon State.
Oregon had a 21-point lead with 4:46 remaining in the third quarter, but allowed Oregon State to storm back and win 38-34 in stunning fashion.
With a win, Oregon would have locked up a spot in the league championship game against USC next weekend. Instead, the Ducks now have to sweat out the result of Saturday night's Washington vs. Washington State game in Pullman.
And they have nobody to blame but themselves.
