On-loan full-back Jay McEveley is likely to be out of action for a month after injuring a medial ligament in the 2-1 defeat at Cardiff. McEveley picked up the knock in the incident which led to Fabian Wilnis's red card.
The Blackburn player will have scans later in the week to confirm the extent of the problem.
McEveley also misses a Scotland Futures training camp being held next week. The 20-year-old has been capped by England at U20 and U21 levels, but is keen to switch his allegiance to the Scots.
