Sasa Papac is a doubt for Rangers' Clydesdale Bank Premier League game against St Mirren.
The left-back is suffering from a sinus problem and looks likely to miss the clash at Ibrox.
Jamie Ness is out with a groin injury, while Kyle Bartley is still recovering from a hernia operation.
St Mirren have an unchanged squad with midfielders Hugh Murray (knee) and Aaron Mooy (back) yet to return to full training.
Defender Darren McGregor (knee) is a long-term absentee.
Rangers (from): McGregor, Whittaker, Papac, Bocanegra, Goian, Wylde, Davis, Edu, Bedoya, Lafferty, Wallace, Jelavic, Ortiz, Broadfoot, Perry, Healy, Alexander, Naismith.
St Mirren (from): Samson, van Zanten, Mair, McAusland, Tesselaar, McLean, Thomson, Goodwin, Teale, Hasselbaink, McGowan, Thompson, McShane, Smith, Carey, Barron, Haddad, McKee.
