Thomas caught a pair of 12-yard scoring passes and ran for a 38-yard touchdown. He had 64 yards rushing on three carries and four receptions for 55 yards.

Mariota finished 19-of-23 passing for 216 yards and running back Kenjon Barner scored a pair of first-half touchdowns for the Ducks.

Arkansas State was led by quarterback Ryan Aplin, who threw three touchdown passes and ran for another, but all came when the game was out of reach and against Oregon’s reserves.
