Riley Nelson, BYU: Having been sidelined for two weeks with a back injury, is Nelson healthy enough to lead the Cougar offense?

Key matchup

BYU secondary vs. Oregon State QB Cody Vaz: Vaz, who hasn't taken a snap in a game since 2010, is making his first start. BYU is No. 1 in the nation in rushing defense, so the Beavers could look to throw the ball plenty. Vaz has a couple of outstanding receivers at his disposal, but will he be able to deliver the ball to them?

Injury report

Oregon St.: Quarterback Sean Mannion is out indefinitely with a left knee injury.

BYU: Quarterback Taysom Hill is out for the season with a left knee injury.
