Rangers have suffered more injury problems in defence after a scan revealed Emilson Cribari has torn his calf.
The Brazilian centre-back faces a month on the sidelines with Sebastien Faure already out after hernia surgery, the same procedure Ross Perry is expected to undergo following discussions with a specialist this week.
Rangers manager Ally McCoist, whose team face East Stirlingshire on Saturday, told RangersTV: "Emilson has a first degree tear in his lower calf just above the Achilles and it looks like he will be out longer term too."
He added: "It looks as though Ross has a hernia problem which will need to be operated on and that is going to be six or seven weeks sadly.
"So it looks as though we will be without these two lads for a number of weeks now.
"Sebastien will also be five weeks minimum so that's another problem.
"However, I felt Chris Hegarty and Lee McCulloch did well at the heart of the defence last Saturday."
