EUGENE -- Oregon could once call on Drayton Carlberg to fill in at defensive end as Austin Faoliu remains hampered by an ankle injury he suffered last month.
Oregon coach Mario Cristobal said Faoliu, who was again limited during Wednesday's practice, is "50-50" to play against Arizona on Saturday (7:30 p.m., ESPN).
Faoliu missed the game at Cal, returned against Washington and had four tackles with .5 for loss and had one tackle as a backup last week against Washington State.
Carlberg, who had two tackles against Cal, one against Washington and one against Washington State, has worked with the first-team defense again this week with Faoliu out.
