Isaiah Newell ran for the go-ahead touchdown with 8:11 remaining, and No. 22 Oregon State took advantage of critical mistakes in the fourth quarter by No. 10 Oregon to rally for a 38-34 victory on Saturday.

The Beavers (9-3, 6-3 Pac-12, No 21 CFP) trailed 31-10 late in the third quarter and 34-17 early in the fourth, but the Ducks (9-3, 7-2, No. 9 CFP) gave their rivals a short field on three consecutive possessions, leading to touchdowns.

First, Oregon gave up a 48-yard kickoff return by Silas Bolden, and a facemask penalty set up Oregon State at the Ducks 36. Newell ran for a 15-yard touchdown to make it 34-24.

Next, Oregon punter Alex Bales dropped the snap and fell on the ball at his own 2. Two plays later, Ben Gulbranson pounded it in from 1 yard to get Oregon State within 34-31.

Oregon then went for it on fourth-and-1 at its own 29, and quarterback Bo Nix was stopped for a 1-yard loss on the Ducks' only called QB run of the game. Newell scored four plays later, with a convoy of blockers helping to push him into the end zone from 6 yards out.

The Ducks can still make the Pac-12 championship game but needed Washington State to beat rival Washington later Saturday. If Washington wins, No. 14 Utah would advance to the title game against No. 5 Southern California.

Oregon State ran for 268 yards and five touchdowns, overcoming its lack of a passing game. Damien Martinez led the way with 103 yards on 15 carries. Ben Gulbanson was just 6 of 13 for 60 yard with two interceptions, but he ran for two scores. Newell scored on his only two carries of the game.

Nix passed for 327 yards and two touchdowns and Oregon finished with 470 total yards, but Nix's inability to run was a major factor.
