St Mirren manager Stephen Robinson faces their biggest game of the season with no experienced strikers available after Curtis Main picked up a knock at Celtic.
Main hit the post after netting a double in St Mirren’s 2-2 draw against the champions but is a doubt for Wednesday’s trip to face one of his former clubs, Aberdeen.
Tony Watt and Jonah Ayunga were already ruled out for the season while Alex Greive is struggling with a niggle and was not expected to feature again.
Lewis Jamieson, 21, and 19-year-old Kieran Offord could be in line to make their first Premiership starts of the season.
“Curtis Main has not trained since the game,” Saints manager Robinson said. “He has taken a knock but he had an X-ray and there is no break, but he is unlikely to train.
“I think he likes scoring against Aberdeen, he enjoyed his goals the last time, so he will do everything in his power to be fit.
“Alex Greive is with the physio running. We are just going to have to assess those two at the last minute.
“We have no senior fit strikers. We have young LJ and Kieran, who are very, very good young players, who may have to come into the fold, depending on where we are. We will have a session in the morning and see where we are.
“I have no qualms in throwing the two young boys in. As much as I want our senior strikers fit, especially after Curtis’s performance on Saturday, we will go with real belief whoever is in the team.”
Saints have been disappointed to lose leads against Hearts and Celtic in their last two matches but are only two points behind Hibernian with two games left in the battle for fifth and a possible European place.
Robinson is backing his side to play without fear and believes all the pressure is on Barry Robson’s Aberdeen following their defeat by Hearts on Saturday.
“We over-thought it at Hibs as a group, not to get beat, and didn’t play with our usual fluency, we didn’t press with our usual fluency, and we have just put that to bed,” he said.
“We spoke as a group and backed what we do: pressing teams how and when we want to press them, and getting on the ball and playing, and enjoying the occasion.
“We are under no pressure whatsoever. Nobody expected us to be here. Everyone expects Aberdeen to be third, everybody expects a fight between them and Hearts and Hibs.
“We shouldn’t be there in people’s eyes but we are, deservedly. We go there with no pressure but a real appetite to get a result.
“Barry’s done a tremendous job there but the expectations at Aberdeen are they should be in the top three.
“So that’s the pressures they have to live with. We will go there with a free mind and an energy to match them, because we will need to as they are a very good side.
“There can’t be any fear. We have everything to gain and Aberdeen have everything to lose.”
