Red-shirt senior Kuony Deng forced a pair of fourth-quarter fumbles, both recovered by Cal, to help the Golden Bears take a 21-17 upset victory over No. 23 Oregon in Berkeley. Both fumbles were forced in Cal territory to end potential go-ahead drives, including the final one just inside the one-minute mark recovered at the Cal 36-yard line on the Ducks' final offensive play of the game.
