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 of Oregon's 55-15 win over Oregon State at Reser Stadium on Friday.

The senior went down following the 14-yard return, his only touch of the game, and left the field on crutches.

"He took a pretty good shot," Oregon coach Mario Cristobal said. "Maybe - I don't know, I hate to speculate. But we did put him in crutches, we braced him up because you just want to be very safe with that. We'll get him MRI'd (in Eugene) and he had the X-ray here."

The Ducks lost quarterback Justin Herbert before halftime with a right shoulder injury and relied almost exclusively on its only two healthy running backs to win the rivalry game.

CJ Verdell had 23 carries for a career-high 187 yards and four touchdowns and a 21-yard touchdown catch, and Travis Dye had 33 carries for a career-high 199 yards and two touchdowns.
