Town manager Joe Royle has admitted that he may look at bringing in a loanee if both Tommy Miller and Fabian Wilnis are unavailable for this Sunday's Sky game at Sunderland (KO 1pm).
Miller has an injured elbow, while Wilnis has picked up a wrist problem and both are considered doubts.
Royle has been tracking a number of potential loan players all season but, with money tight, is loath to bring anyone in unless they are going to play a part.
The Town boss said: "If both players wee missing we would be heading towards a crisis and we would have to look at bringing someone in."
Royle says the club should be in a position to know whether either player will miss out by Wednesday.
