Rangers manager Walter Smith has urged Fifa to end weeks of uncertainty and reach a verdict on Daniel Cousin's proposed transfer to Fulham.
Cousin has scored nine goals for Rangers this season
A £3m fee was agreed but special dispensation is required because the striker also played for Lens this term.
Fifa have not yet set a date for making a ruling on the 30-year-old's case.
"The problem is that it's taking so long that his lack of match practice is going to be a problem whichever way the decision goes," said Smith.
"If he goes to Fulham, they will obviously have the same problems as ourselves at the present moment, that he won't have had sufficient match practice in the last few weeks.
"So, it's beginning to get to that stage where we are going to have to look and see what's best for both parties.
"We can use him just now, he still remains a player we can use.
"But it's complicated by the fact that, once we have made arrangements to transfer the player and he has gone through medicals at Fulham, it becomes awkward to play him because you take the chance of the player becoming injured.
"It's an awkward situation and not one that we're used to but we are hoping for a resolution shortly.
"It would only be fair from all sides that they do that and let us get on with whatever the decision is.
"If the decision goes against the transfer, then we will have no hesitation in bringing him back and playing him. There is no problem with that."
Fifa regulations forbid a player from playing for more than two clubs in one season.
Cousin played an InterToto Cup match and 20 minutes of league football for Lens before completing his summer switch to Ibrox.
With Jean-Claude Darcheville banned for three European games, Cousin may be a handy player to have as Rangers prepare for their Uefa Cup tie with Panathinaikos.
But Smith insisted: "We wouldn't have agreed to the transfer if we didn't feel we could cover for injury or suspension.
"That's a basic thing. We would rather have Jean-Claude playing for us but we take the chance every week of picking up injury or suspension."
