I agree on both Heraghty and Ferrie. Muir has not shaped up in Div 1 for East Fife, Forfar, or Airdrie in the past. He also has previous for going in the huff when dropped. I am sorry about his injury, sounds unpleasant, but he is unlikely to replace Ferrie who is a superior all round keeper. I think Wullie might have to settle for Div 2 if he wants guaranteed first team football.
