Bo said in today's presser that Qvale and Thompson are both day-to-day with injuries. Ben Cotton and Andrew Rodriguez are doubtful for Michigan.
EDIT - here's an updated from the LJS:
Bo Pelini was asked about several injuries Monday.
-- Starting tight end Ben Cotton is doubtful for Saturday's game at Michigan, the Husker coach said. Cotton's right arm was in a sling after the Penn State game.
-- Starting LG Andrew Rodriguez also is doubtful. He didn't make the trip to Penn State because of an undisclosed injury, which I believe happened late last week in practice.
-- Reserve offensive guard Brandon Thompson and backup wideout Khiry Cooper are "day-to-day" because of injuries.
-- Pelini expects reserve guard Brent Qvale to return to action this week. He could be a big help with depth behind guards Seung Hoon Choi and Spencer Long, who played every down at Penn State.
