Tony Mowbray admits he is uncertain as to how many of his injured stars will be available on Saturday.
The Celtic boss is preparing for an Active Nations Scottish Cup quarter-final with Kilmarnock at the weekend, but has his hands tied by a crippling injury list.
Mowbray was without Glenn Loovens, Jos Hooiveld, Thomas Rogne, Marc-Antoine Fortune, Diomansy Kamara, Niall McGinn and the suspended Scott Brown for Sunday's 2-0 victory over Falkirk, but insists he will have no complaints if forced to field a number of his fringe players again at Rugby Park.
"The treatment room is full as you could see with the team we had out against Falkirk, but we will wait and see," he said.
"I'm not sure how they are coming along.
"They will have to get their boots on in training next week at some stage to be in contention for the weekend.
"But what the victory over Falkirk has given me is food for thought.
"The ones who didn't play will have to fight to get back in the team if the team continues to win.
"Players will have to compete for their places."
Of those who caught the eye against the Bairns, Mowbray admits teenage defender Josh Thompson probably enhanced his reputation the most.
"(Morten) Rasmussen played his part in Keane's first goal," he said.
"I thought (Marc) Crosas and (Landry) NGuemo were good in central midfield on a difficult surface and I thought Aiden (McGeady) played well.
"But Josh Thompson grows in stature every day.
"He was playing against a big, strong powerful boy (Enoch Showunmi) with a lot of experience and if you put it in context, Josh is just a young boy who has played seven or eight games in his career.
"So he is doing okay."
