Dundee United will be without centre-half Frederic Frans for tomorrow’s game and beyond after the full extent of his groin injury was confirmed by a specialist.
Calum Butcher will also be missing through suspension but Rachid Bouhenna is back after recovering from a facial knock against Falkirk last Saturday.
United boss Robbie Neilson said: “Freddy is still struggling with his groin and we are expecting him to be out for six weeks which is disappointing.
“Bouhenna will be back in but Butcher is out for this one which is disappointing and there will have to be a change.
“We will look at it and make a decision.”
Meanwhile, United’s American owner Mark Ogren, who watched Tuesday night’s league game against Inverness, will also be in the stands for the Scottish Cup tie against the same opponents.
Neilson added: “He will be here Sunday and I think he leaves early next week.
“We’ve had a few good meetings – it’s been great. He’s been pleased with the way things have been going.
