Rangers are set to be without Borna Barisic as they welcome Livingston on Saturday, as they look to keep their slim title hopes alive.
Defeat to Kilmarnock at Rugby Park in midweek saw Rangers slip 10 points behind Celtic and while they have a game in hand to play they can't afford any more dropped points.
Manager Steven Gerrard looks set to be without Barisic for the second match in a row as the Croat continues his recovery from a thigh injury.
Jermain Defoe remains sidelined with a calf injury and centre-back Filip Helander will not be fit to play as he battles a foot problem.
Livingston, meanwhile, will hope to have Marvin Bartley available.
The midfielder was taken off halfway through their midweek win over St Mirren with an ankle injury.
Chris Erskine (groin) remains out, while Cece Pepe and Nicky Devlin are still working their way back from injury.
