Aberdeen defender, Michael Devlin has been ruled out for three months after suffering an ankle tendon injury.
The injury occurred in a training ground incident this week and the player now faces surgery.
Mikey has only made two appearances this season, off the bench in the recent double header against St Mirren.
His injury nightmare comes, after he returned to training following suffering a hamstring injury in pre-season.
Derek McInnes said: “Mikey Devlin has picked up an injury again, which is a real blow.
“He took a sore one, he has had it scanned and unfortunately he is going to need an operation on a tendon injury, which is going to keep him out probably three months.
“Totally innocuous, it was a shot from Ryan Hedges that he blocked at training on Tuesday. When you look at the incident I am surprised at the nature of the damage.
“I feel sorry for the boy, he has had such a hard time.
“We arranged a game last Tuesday against Celtic for him to play in but he felt his groin tighten. He trained later in the week and managed to come off the bench on Saturday but he has not started a competitive game since February, and littered in between then and now there have been various injuries.
“It’s so frustrating for him and disappointing.”
“No matter how many times Mikey has been through this, we shouldn’t just assume he knows how to deal with it,” he said.
“Having had a lot of injuries myself as a player, it’s normally just about getting your operation and then doing your rehab and working towards it.
“Sometimes when injuries accumulate there is that, ‘why me?’ and you can feel sorry for yourself.
“But Mikey has been through a lot in his career and he has always come out the other end. This is just another test for him.
“We are extremely disappointed, selfishly, right away you think, ‘we are without a good player’. But the main concern is for Mikey to get the operation and get back as quickly as possible.”
He missed the entire 2017/18 season after suffering cruciate ligament damage in his final for Hamilton and also missed three months of his first campaign at Pittodrie with a foot problem.
Aberdeen will also be without Niall McGinn and Dylan McGeouch for our match against Ross County this Saturday. Both are being targeted for returns, following a full week’s training next weekend.
