Celtic defender Cameron Carter-Vickers will miss Saturday’s game with St Johnstone and is a doubt for the Champions League clash against Borussia Dortmund.
Carter-Vickers sat out last weekend’s Premier Sports Cup win over Falkirk with a toe injury and will be absent again in Perth.
Manager Brendan Rodgers said: “Callum will miss (Saturday), he’s just got pain on his big toe, in the join there. So we just have to look at it each game.
“He’d been playing with it for a little while but we have got to try and manage it now because he was in pain in the Bratislava game. So hopefully it will settle down quite quickly and then we’ll see where he’s at it for Tuesday.
“It’s difficult to tell. Our concentration is on this game really and then we’ll see where he’s at over Sunday and Monday.”
Rodgers does not believe the injury will require any major treatment.
“It’s not that, it’s just the tolerance of pain,” he said. “He’d gone through a lot and pushed him through a lot, but it’s not getting any better and he was having to go through too much pain really.
“He’s a tough character, Cam, but we just felt that it’s obviously one of those ones that with rest it will self-correct.
“But there comes a point where you could just see he wasn’t quite at the level that he would want to be at and I would want him to be at, and when it’s at that point you want to take him out and let him recover.”
Full-back Alistair Johnston will return in Perth after recovering from a minor injury and training all week
