CORVALLIS – Oregon State will enter Saturday's game against Arizona as a rare favorite, but still has question marks at multiple positions.
The primary new addition to the Beavers' injury report, which the team released Tuesday, is sophomore wide receiver Seth Collins. Collins, who ranks second on the team with 36 catches for 418 yards, has been hospitalized with an illness since Sunday. He is in fair condition and will not play Saturday.
Running back Ryan Nall (foot) is questionable for the second consecutive week. Nall, the team's leading rusher with 93 carries for 672 yards and eight touchdowns, did not play at UCLA.
