Oregon State's offensive line took a hit this week when starting left tackle Michael Philipp injured his left knee and now may miss the rest of spring practices.
Philipp will have his knee scoped on Wednesday, according to The Oregonian.
As a true freshman, Philipp started all 13 games as the Beavers left tackle and earned a number of freshmen All-American honors.
The offensive line already was missing starting guard Grant Johnson (shoulder).
Timi Oshinowo, who missed the 2009 season with a knee injury -- an injury that pushed Philipp into the lineup -- will step in for Philipp. Starting right tackle Mike Remmers might see some action there as well, as could Wilder McAndrews, who is trying to come back from a long-term wrist problem.
