Christopher Jullien is a doubt for Celtic's match against Livingston.
The French defender will be assessed before kick-off as Neil Lennon's side welcome Gary Holt's men to Celtic Park.
Jullien picked up a knock in training on Thursday, and could miss out as the home side aim to go top of the table.
League leaders Rangers don't play until Sunday, when they face a tricky encounter against Hibs at Easter Road. A win by at least two goals would see Celtic leapfrog their rivals.
Winger Mikey Johnston continues his recovery from calf surgery.
There will be no return to Celtic Park for Anthony Stokes, who left Livingston on Monday after failing to adapt to their artificial pitch.
Manager Holt says his squad will be unchanged for the trip to Glasgow.
Steve Lawson was back on the bench last weekend following a foot injury while fellow midfielder Keaghan Jacobs is pushing for a return from a similar problem. Centre-backs Jack Fitzwater and Alan Lithgow remain out.
Celtic squad : Barkas, Jullien, Taylor, Brown, Christie, Ntcham, Ajer, McGregor, Elhamed, Edouard, Forrest, Bain, Bitton, Ajeti, Duffy, Klimala, Turnbull, Elyounoussi, Soro, Frimpong
