Jimmy Thelin has confirmed Jamie McGrath will be out for the next two months of Aberdeen’s European push.

The Irishman has suffered a shoulder injury against Hearts and will be out until the end of March, at the earliest. McGrath has not long returned from a similar injury but this time it is the opposite shoulder he has hurt. Thelin confirmed: “Jamie is out for a couple of months because of his shoulder injury. He can play in different positions. He's always giving everything. Sometimes you have some consistent pattern injuries, but now we have these shoulder injuries. It's really bad luck. Actually, we tried to save Jamie because of his legs in this game and then after 30 seconds he fell and hurt his shoulder in that game.”

McGrath adds to Aberdeen’s growing injury list that includes Gavin Molloy, Ester Sokler, Vicente Besuijen, Jack Milne and Dimitar Mitov. Midfielder Dante Polvara also misses Saturday's game through a minor issue. Aberdeen got back to winning ways in the cup last weekend at Elgin City and he wants to back it up with three points in the league against St Mirren.

It could be an emotional day as the Dons pay tribute to their former manager, Jimmy Calderwood, who passed away earlier this week. Thelin said: “Yes, I haven't met him personally, but he's had a huge impact on the club and he means a lot to a lot of people. “I’m sad for his family.

“I think he's always a historic person for the club and you always have to show this respect. I think that's really important.”

The Swede believes everyone at the club has been given a shot in the arm from the win at Elgin and look forward to the visit of the Buddies. Thelin claimed: “We're looking forward to it, of course. “I think we are well prepared.

“Our aim is now to be a more stable team. We have worked a lot this week to take the positive things from the cup game.

“There has been more focus on these things and trying to do this really properly on Saturday. I think some players are back in training, the competition is stronger in the training sessions and the intensity is increasing.

“It's good for us that we have this intensity and everybody feels the competition inside the squad is really strong. Everybody has to be on the limit to play the games. We also have different characteristics to use against a specific opponent.”
