Rangers will be without Kyle Lafferty and Steven Smith for their Clydesdale Bank Premier League game against St Mirren.
Both players are suffering from food poisoning and have been ruled out of the match at Ibrox.
Madjid Bougherra has failed to recover from a knee injury, meaning teenager Danny Wilson is set to make his home debut.

St Mirren midfielder Steven Thomson returns from illness on Saturday.
However Lee Mair is suspended following his red card in the 2-0 defeat by Hamilton last weekend.
