Rangers have been dealt a double blow with the news Kyle Lafferty could be out for a further six weeks and Kyle Bartley for a month.
Striker Lafferty has been out of action for a number of weeks already with a hamstring tear and faces being sidelined for another four to six weeks, while on-loan Arsenal defender Bartley, who missed last week's loss to Kilmarnock, faces up to four weeks out with a groin problem.
Bartley could now find himself the victim of administrators' anticipated cuts in staffing next week, given that he could return to parent club Arsenal for treatment.
Ibrox manager Ally McCoist told Gers' official website: "Kyle Bartley has a problem with his groin and he is going to be out for three to four weeks.
"It's certainly another problem we could do without because we are stretched.
"We know that whoever comes in for the injured players will have to be on top of their game."
Lee Wallace has also been ruled out for this weekend's Scottish Premier League trip to Inverness due to a knock sustained in last week's defeat to Kilmarnock.
Fellow left-back Sasa Papac is suspended for the visit to the Highlands, while manager McCoist is hopeful full-back Steven Whittaker will soon return following a hernia operation.
