Gary Hooper, Sam Hutchinson and Morgan Fox are all ruled out for the rest of the season as Wednesday’s injury woes continue.
Long-term absentee Hooper recently saw a specialist in London and Jos Luhukay has confirmed he will not play again during this campaign.
Hutchinson is also ruled out after suffering an ankle injury against Preston on Good Friday and Morgan Fox has joined the list of players who won’t kick another ball this season after a hamstring problem forced him off at Sunderland on Easter Monday.
Injuries have already seen Ross Wallace, Steven Fletcher and Sean Clare sidelined for the remainder of the season.
