Ross County defender Darren Barr will have cruciate ligament surgery tomorrow which will keep him out for the rest of the season.
Barr joined County on a one-year contract from Kilmarnock in the summer, having missed a large part of last season with a hip injury.
The news comes as a further blow for the 29-year-old, who suffered the injury against the Dons on Monday, November 3.
Manager Jim McIntyre fears it is inevitable Barr will miss the remainder of the season and said: “He’ll be out for a minimum of six months. It’s a cruciate ligament so I don’t think it’ll be any less time than that.”
McIntyre also confirmed fellow long-term absentee Rocco Quinn, ruled out until February with a hip injury, will come off his crutches next week.
McIntyre has urged his side to be more clinical in attack following Saturday’s 2-1 defeat against St Johnstone.
McIntyre’s men did not struggle to create chances, but he reckons they must be more clinical.
He added: “We played really well in the second-half against St Johnstone and we should have taken something from the game.
“But we’ve got to take our chances when they come and I think that was the difference between the sides.
“St Johnstone weren’t that much better than us in the first-half, but they were certainly more of a threat.
“But our second-half performance against St Johnstone was excellent. We created a number of opportunities but we just didn’t have that final touch on it. That was the disappointing thing.”
County midfielder Filip Kiss was adamant he should have had a penalty after appearing to be taken down by Chris Millar, however McIntyre feels his side must take responsibility for the chances they missed.
McIntyre added: “Rather than talk about penalty decision that went against us, I would rather look at the fact we created a couple of chances but never took them. I think that was the difference.
“It was great to see big Jake Jervis get his goal. I thought he put in a really strong performance again.
“That’s two games in a row now where he been really working hard for the team, winning a lot of headers and doing what a forward needs to do.
“He’s taking on board what we’re saying. I thought he played really well. It’s up to us to show belief in him. Then it’s up to Jake to take it on and show what a good player he is, because we certainly think he is.”
