Aberdeen boss Craig Brown admits he is uncertain of the extent of defender Andrew Considine's injury.
Considine missed the 1-1 Clydesdale Bank Premier League draw at Aberdeen last weekend and the duration of his lay-off is unknown.
Speaking ahead of Saturday's match with Dundee at Pittodrie, Brown said: "There is no update on Andrew Considine. We don't know how long he will be out for.
"At the moment his foot is in a boot which is inflated and is made of plaster and he takes it off when he is getting treatment.
"If it is a fixed plaster you can't do that. That means the medical team at the moment don't think he needs a solid plaster cast.
"There is a thought that it is a previous injury that has aggravated recently. If that is the case it might be good news."
Gary Naysmith is to be included in the squad after making his return from a hamstring injury in the Under-20 League.
Brown added: "It is great to have him involved again. He is an outstanding professional. He is a character and a motivator.
"We are lucky to have guys like Gary here along with Russell (Anderson), Gavin (Rae) and Stephen (Hughes). It is great to have their experience in and around the club."
