Oregon State quarterback Darell Garretson will miss the rest of the season because of an ankle injury.
Garretson, who started the first six games for the Beavers, was injured in the second half of Saturday’s 19-14 loss at home to Utah. Afterward he was seen on crutches.
Beavers head coach Gary Andersen announced that Garretson was done for the season at his Monday media availability.
Backup Conor Blount, who was also on crutches following the loss to the Utes, is unavailable for Saturday’s game at No. 5 Washington. The nature of his injury was not known.
Andersen said Marcus McMaryion would start at quarterback against the Huskies. There is also the possibility that Seth Collins, who played quarterback for the Beavers last season before switching to receiver, could see snaps.
