Skipper Steven Caldwell (groin) is definitely out while Clarke Carlisle is rated as only 50-50 with a side strain. Meanwhile Andre Bikey is absent on Africa Cup of Nations duty.
Michael Duff is expected to continue at centre-back and if Carlisle fails to make it that could mean a league debut for young Canadian defender David Edgar, signed in the summer from Newcastle.
Sidelined: Caldwell's groin problem prevents him from facing United
Team (from): Jensen, Carlisle, Edgar, Eagles, Alexander, Elliott, McDonald, Fletcher, Duff, Nugent, Blake, Thompson, Penny, Guerrero, Gudjonsson, Kalvenes, Eckersley.
