St Mirren boss Stephen Robinson is sweating on a potentially serious injury to Northern Ireland goalkeeper Trevor Carson.
The 34-year-old is nursing a knee injury and the club is awaiting a medical update to deetrmine if surgery is required.
A long spell on the sidelines would be a huge blow to Carson who previously worked with Robinson at Motherwell, Morecambe and Northern Ireland.
Carson wasn’t risked in Saturday’s Premier Sports Cup win against Cowdenbeath, with Peter Urminsky stepping in while the club assessed the ex-Motherwell stopper’s knee complaint.
Robinson said: “Trevor is having scans on his knee. He’s seeing the specialist.
“We’ve taken him out of everything at the minute, just to make sure we’re not taking any kind of risk.
“If it had been league games, we may have played him. But we’ll know a lot more soon if he needs to rest it, play through it or something needs done with it.
“It’s a huge concern for us. You think you’ve got your squad together, you maximise the budget that you have and then you get a potential blow like this.
“But it happens and it happens to every manager. You just have to deal with it. Peter came in at the weekend and showed he’s going to be good back up. He’s still a young boy learning the game.”
St Johnstone, meanwhile, have signed Scott McCann, the teenage brother of Northern Ireland midfielder Ali, who left Saints for Preston North End in 2021.
