Dundee United’s already threadbare squad has been gripped by an injury crisis ahead of Saturday’s Championship tie against Morton at Tannadice.
A swathe of players are fitness doubts, with others set to remain on the treatment table long-term.
After having a tooth taken out last week, Paul Quinn came off after 10 minutes at Falkirk, complaining he was feeling drowsy.
It was thought Quinn would be fit for the weekend but the problem has escalated.
He is joined by James Keatings (dead leg), Patrick N’Koyi (hamstring) and Billy King (knock) on a list of doubtfuls for the Morton game.
On Quinn, United boss Ray McKinnon said: “It’s quite serious from what we’ve gathered.
“Some infection has got to his mouth into the abscess following the tooth extraction and it’s had an effect on him. So we just have to wait and see what the doctors are saying about that.
“He’s away to get a heart scan because of it, his heart rate was through the roof on Monday so, hopefully, he’s fine.
“N’Koyi’s still out, he’s struggling with his hamstring, Keatings took a dead leg on Monday in a bounce game, which is a blow for us and he came off after 10 minutes.
“Billy King hasn’t trained either so we’ve got a couple of wee issues leading up to the game but, hopefully, a couple of them will come through that.
“We don’t want to make excuses but we can’t get a settled team on the park right now.”
Ray was hoping to trial a Keatings-Scott McDonald partnership against Morton but that now looks unlikely to materialise.
“We were hoping Keatings would be back this week after playing last weekend,” Ray said.
“We wanted to maybe start to build a partnership but it looks as if he’s going to be out again.
“He looks very doubtful for the weekend. He took a really bad one on his thigh after 10 minutes on Monday and had to come off.
“He can’t bend his leg so it’s not ideal for him because he’s trying to get himself back so quick.
“We’ve only had Scott McDonald up there recently, although we’ve played Paul McMullan up there last Saturday, but he’s not a natural up there.
“We’ll get there, Keats will be back in a week or so. It’s only a dead leg — you never know he might be back on Saturday.”
