Starting Oregon State OLB Dwight Roberson is expected to miss Saturday’s Pac-10 opener at home against Arizona State due to a sprained knee, coach Mike Riley said Sunday.

WR James Rodgers has a minor concussion, but is expected to be back to practice Wednesday. Starting DE Taylor Henry (back) shouldn’t miss any time.

Who takes Roberson’s place will be determined Tuesday. Options include Devin Unga, Keo Camat, Cameron Collins and Michael Doctor. Here’s a link to the full story in Monday’s GT.

Riley wasn’t happy about helmet-to-helmet hits Rodgers and WR Markus Wheaton took in the game.

“I don’t know what to say about that,” Riley said. “It was helmet-to-helmet. James was in the middle and I don’t know if it was inadvertent.”

He was also mad about the non-calls on the horse collar tackles on Rodgers. “The official tired to pull his flag out, but didn’t,” Riley said.
