(Eugene, OR) -- Oregon starting quarterback Justin Herbert was released from concussion protocol and returned to practice. He did not take any reps with the first two units, but took all the reps in a hand off drill against the scout team defense. Backups Braxton Burmeister and Tyler Shough split reps with the first two teams. Ducks coach Mario Cristobal said he would wait until later in the week to name a starter for the Saturday game against UCLA. Leading receiver Dillon Mitchell has yet to practice after his concussion last Saturday against Arizona.
