Barner left the game for the second-ranked Ducks late in the first quarter holding his hand and grimacing on the sideline before being taken to the locker room. He came back to the field before the next series and got on the field for one play without getting the ball.
Barner ran for a school-record 321 yards and scored five touchdowns in last week's win over Southern California. His 19 rushing TDs on the season are two shy of tying LaMichael James' single-season school mark.
Byron Marshall replaced Barner and scored on a 3-yard run on his first play after the injury.
