CORVALLIS -- Oregon's running back corps suffered another injury during the Civil War.
Tony Brooks-James suffered an apparent left knee injury on the opening kickoff of the second half.
The senior went down following the 14-yard return, his only touch of the game, and left the field on crutches.
Oregon's only healthy running backs are CJ Verdell, who entered the fourth quarter with 22 carries for a career-high 186 yards and three touchdowns and a 21-yard touchdown catch, and Travis Dye, who had 22 carries for 119 yards and a touchdown entering the fourth quarter.
The Ducks lost quarterback Justin Herbert before halftime with an apparent right shoulder/collarbone injury.
