Rangers will be without Borna Barisic for their Premiership trip to Perth to face St Johnstone on Sunday.
The Croatian left back suffered a kidney injury during their 3-2 win over Braga in the Europa League, and although he trained on Friday morning, has been ruled out.
That means Andy Halliday is likely to come back into the starting XI while Ryan Jack is also set to return.
The midfielder missed the Braga clash through suspension but should take his place in midfield for Sunday's game.
Liam Craig returns to the St Johnstone squad the game. The midfielder missed the Ross County game with a knock.
Murray Davidson (fractured arm) remains on the sidelines.
St Johnstone provisional squad:
Clark, Ralston, Duffy, Booth, Tanser, McCart, Kerr, Holt, Swanson, Craig, Gordon, McCann, Kane, May, Wotherspoon, Hendry, Butcher, O'Halloran, Jones, Wright, Parish.
