EUGENE -- Justin Herbert returned to practice for Oregon on Wednesday, though he did not take any early reps with the offense, and wide receiver Dillon Mitchell was present but not fully dressed out.
Since Oregon's loss at Arizona last Saturday, Herbert and Mitchell have been in concussion protocol, which was to run though this morning.
Oregon coach Mario Cristobal will speak later this morning to address the latest the availability of the two offensive stars.
Backup quarterback Braxton Burmeister worked with the first-team offense and Tyler Shough worked with the second-team during an early period of practice.
