Oregon State's lengthy injury list added a new name Friday: starting cornerback Brandon Hardin, who will be out indefinitely with a shoulder injury that requires surgery.
Hardin has 15 career starts. The Beavers' secondary was widely viewed as the defense's decided strength heading into preseason practices.
Sophomores Rashaad Reynolds and Sean Martin will move up in the pecking order at cornerback opposite Jordan Poyer. Also, redshirt freshman Malcolm Marable has switched to corner from tailback to bolster depth.
On the positive side of the Beavers' 15-man injury list: Defensive tackle Kevin Frahm may be able to return for the Wisconsin game on Sept. 10. He's been diagnosed with a meniscus tear in his right knee and will have surgery Monday to repair it.
