EUGENE, Ore. (AP) — Oregon's defense found a way to stop Chris Perry — and the rest of Michigan's lauded offense, too.

Perry, the nation's leading rusher going into the game, ran for just 26 yards as No. 22 Oregon upset No. 3 Michigan 31-27 on Saturday in front of the largest crowd ever at Autzen Stadium.

Jason Fife, half of Oregon's quarterback tandem with Kellen Clemens, ran for one touchdown, tailback Terrence Whitehead rushed for another, and the Ducks (4-0) were able to take advantage of some key Michigan (3-1) errors before 59,023 yellow-clad fans.

Michigan (3-1), making its first road trip of the season, narrowed it with John Navarre's 36-yard TD pass to Steve Breaston with 2:18 left, but couldn't get any closer.

After Oregon jumped out to and early lead, the Wolverines turned up the pressure in the fourth quarter.

Navarre's 9-yard scoring pass to Breaston and conversion pass to Braylon Edwards made it 24-21, but the Ducks answered with Jordan Carey's fumble recovery in the end zone with 6:55 left.

It started when Keith Lewis blocked Adam Finley's punt. The ball sputtered just out of reach of Oregon's Ryan Shaw, but free safety J.D. Nelson got to it, only to fumble on the 1 before Carey landed on it in the end zone for the score.

Michigan, which was averaging more than 307 yards on the ground so far this season, lost 3 yards on 19 carries.

Navarre completed 28 of 55 passes for 360 yards and three touchdowns, but he wasn't able to carry the offense.

Clemens, who started for Oregon, was 15-of-23 for 160 yards, while Fife was 5-of-8 for 93 yards. For the fourth straight game, the pair did not throw an interception.

On its first series of the game, Oregon went for it on fourth-and-1 on Michigan's 25, and Clemens hit Tim Day with a 21-yard pass play to put the Ducks on the 4.

Michigan's defense was able to hold off an Oregon TD, even when it appeared that Clemens had punched through on a 1-yard keeper. On fourth down, Oregon was called for a false start and pushed back five yards.

The Ducks decided to go for the field goal, but Jared Siegel's 22-yard attempt was blocked by Marlin Jackson and scooped up by Jeremy LeSueur — who ran untouched 78 yards down field for the score.

While Finley missed the extra point, Michigan still managed a 6-0 first quarter lead even though the Wolverines' overall time of possession was just 56 seconds. Oregon had possession for the remaining 14:04.

The Ducks turned things around early in the second quarter on Whitehead's 19-yard TD run.

The Wolverines were hurt on the next series when they tried a fake punt and the snap was fumbled by linebacker Scott McClintock. Oregon defensive end Igor Olshansky jumped on the ball and the Ducks went on to score on Jason Fife's 15-yard run.

Oregon further surprised the Wolverines when Steven Moore ran a punt back 61 yards for a touchdown, making it 21-6 at halftime.

Siegel opened the second half for the Ducks with a 36-yard field goal.

Michigan narrowed the margin to 21-13 when Navarre hit Jason Avant with a 23-yard pass that Avant stretched into the end zone.

Michigan, a perennial Big Ten force, authoritatively shut down Notre Dame 38-0 last Saturday to move up two spots in the national rankings. And until the loss to the Ducks, Perry was averaging 183 yards a game.

The Wolverines have lost four straight road openers.

The Ducks jumped into the Top 25 after a 48-10 rout of Arizona last Saturday.
