The offensive line was supposed to be a strength for Oregon State this year. The Beavers had four returning starters coming into the year.
Injuries have hit the line hard, though, which has contributed to the Beavers struggling in the run game. Riley said help is on the way, however, as the Beavers look to the second half of the season.
"We've got a chance if we can stay healthy this week," he said. "We have a bye after this game and we should get two guys back. We're four total down and two of them should be back, maybe three of them possibly after the bye. I think we've got a chance to get stronger as we go."
