St Mirren will be without Kyle Magennis and Danny Mullen until after the winter break.
Midfielder Magennis and striker Mullen both went off injured during last Wednesday’s draw with Hibernian.
Manager Oran Kearney told the Paisley Daily Express: “Kyle’s hurt his hamstring – it’s a tear, which isn’t good news at all. He is probably going to be out for months rather than weeks.
“Danny has had an operation on his foot so he will also be (sidelined for) six to eight weeks.”
