Oregon State rallied from a 28-point second-half deficit, as Jake Luton came off the bench to throw for 310 yards and three touchdowns to beat Colorado 41-34 in overtime.
Jack Colletto ran a 1-yard quarterback sneak in overtime to give the Beavers their first lead of the game. OSU's defense then responded, turning back four consecutive Colorado passes from inside the 10 to pull off the upset.
Oregon State, a 24-point underdog heading into the game, ended a 22-game road losing streak. It was the Beavers' first Pac-12 and FBS win since beating Oregon in the 2016 Civil War.
