David Healy is already ruled out of the game due to a suspension.
Frazer Richardson is now also facing a new spell on the sidelines after suffering further problems with his troublesome knee. The 23-year-old has been sent for a scan after suffering a reaction following his return to training earlier this week.
Injury-plagued Eirik Bakke is facing another two weeks out after picking up a new injury in training. The Norwegian international had recovered from the hamstring strain he sustained while on loan at Aston Villa and was on the verge of a recall to the squad. But he will now not probably play until March.
Meanwhile, Rob Hulse has consulted a London specialist this week in a bid to resolve a long-standing hip problem. The striker is expected to be named in the squad for the weekend though.
