Tommy Lee saw a specialist on Tuesday afternoon after suffering an injury in Tuesday night's game against Oldham Athletic.
The keeper fell awkwardly late in the game after coming out to collect a cross. After attempting to continue playing, he was forced to leave the field and was replaced by Richard O'Donnell.
The results of the specialist's findings will be known on Thursday and caretaker-manager Tommy Wright will provide an update on Tommy's fitness ahead of Saturday's trip to York City.
The news will be revealed first here on the official website.
