Oregon State will be without at least two more starters due to injury Saturday at UCLA.
The Beavers' injury report, which the team released Tuesday, announced that left guard Gus Lavaka and outside linebacker Bright Ugwoegbu are out.
Lavaka, a 22-year-old freshman, has started the last five games after junior Fred Lauina went down with a leg injury at Colorado on Oct. 1. Lavaka (knee) has been part of a resurgent offensive line that reshuffled its parts when left tackle Sean Harlow returned for the Colorado game. He left the 26-15 loss to Stanford with his injury Saturday and Lauina, who has been back for multiple weeks, is likely to replace him.
