Celtic left-back Greg Taylor faces at least two weeks out with a hamstring injury.
The Scotland international went off in the first half of Celtic’s 2-2 draw with Rangers on Monday after aggravating a problem he had experienced in his previous match.
Ange Postecoglou revealed the update on Friday.
He said: “Greg has got a slight hamstring (injury) so we got a scan. It’s not too serious but he will definitely miss a couple of weeks.”
The Celtic manager revealed that the league leaders are still missing Sead Haksabanovic, Stephen Welsh and James McCarthy for the game against Kilmarnock on Saturday.
“In terms of the ones returning, they are all closer but none are available for,” Postecoglou said.
