St Mirren manager Danny Lennon has no fresh injury worries for the visit of Gers.
Goalkeeper Paul Gallacher, David Barron and Craig Dargo (all knee), Steven Thomson (calf) and Sean Lynch (knock) are all making good progress.
However, none of them will be ready in time for the visit of the Scottish champions.
Vladimir Weiss has been rated doubtful for Rangers.
The winger has been struggling with a heel problem and could miss the visit to Paisley on Sunday.
But Madjid Bougherra and Kyle Lafferty are both expected to recover from slight calf strains ahead of the match.
St Mirren (from): Samson, van Zanten, McAusland, Potter, McGregor, Travner, Cregg, Mooy, Murray, Higdon, McGowan, Wardlaw, Mathers, McCluskey, Brady, McQuade, Mclean, Kennedy.
Gers (from): McGregor, Papac, Weir, Bougherra, Broadfoot, Davis, McCulloch, Edu, Naismith, Weiss, Fleck, Lafferty, Miller, Whittaker, Foster, Loy, Hutton, Alexander.
