Ally McCoist has revealed that strikers Kyle Lafferty and Nikica Jelavic are both struggling with injury after Rangers returned to form with a 3-0 win over Motherwell at Ibrox.
Jelavic - the Gers' top scorer with 12 league goals - missed Monday's SPL win over the Steelmen with a groin problem, and the Scottish champions were dealt another blow when Lafferty was carried off early on.
Strikes from David Healy, Sone Aluko and an own-goal from Stephen Craigan ensured a comfortable win for Rangers, but McCoist admits he is keen to see his first-choice attacking line-up back to full fitness.
"Nikica didn't make it with a groin strain, he attempted to train on Sunday and had a go on Monday morning, but he wasn't fit enough to play or be involved," said McCoist.
"The injury to Lafferty is a big, big blow for us. Make no mistake about it. I don't know the full extent of the injury, but it looks like he has pulled his hamstring and my guess would be four or five weeks. Hopefully Nikica's is more short term."
Jelavic has been tipped by many pundits for a January switch to the Premier League, but McCoist is more concerned with which players he can bring in to Ibrox and is planning talks with owner Craig Whyte.
The Rangers boss said: "The only enquiries we have had are for John Fleck for loan, which would probably be put on the back-burner now.
"I'll look at the whole thing again on Tuesday and reassess the injuries, but I would have to say it would be doubtful he would be going anywhere."
"I'll sit down with Craig tonight or tomorrow and have a wee chat and see where we are.
"We look as though we need strengthening in forward areas. The injuries to Jelavic, Lafferty and long term to Steven Naismith certainly hasn't done anything to change my opinion. We know we need bodies in."
