QPR manager Neil Warnock is due to meet with the club's owners on Monday to discuss possible signings.
Warnock wants two strikers and at least one defender in the wake of injuries to Jamie Mackie and Patrick Agyemang, and the end of Kyle Walker's loan spell.
Rangers' Bernie Ecclestone-led board have spent heavily since taking over at Loftus Road in August 2007.
But they have indicated they do not want to spend on transfers or loan fees between now and the end of the season.
That would leave Warnock to chase loan deals in which Rangers would pay only a player's wages, and he is set to discuss a number of possible options with his bosses.
The R's are five points clear at the top of the Championship, but the loss of Mackie, who suffered a broken leg at Blackburn on Saturday, is a significant setback for them.
They have also lost Walker, after the 20-year-old's loan move to Aston Villa from Tottenham dashed Rangers' hopes of extending his stay in west London.
Warnock then wanted to sign Kyle Naughton from Spurs, but was told his club would not match the offer made by Leicester, who subsequently extended the right-back's loan spell at the Walkers Stadium.
