Queens Park Rangers have suffered a blow after on-loan Portsmouth defender Martin Cranie broke his leg in Tuesday's 2-1 defeat at Coventry.
England U21 international Cranie joined Pompey in the summer
An X-ray confirmed that Cranie, 21, had fractured his fibula, and he has now returned to Pompey for treatment.
"It's similar to the injury Simon Walton sustained in pre-season," physio Paul Hunter told QPR's website.
The England Under-21 international had started six Championship games since moving to Loftus Road in October.
Rangers also lost Mikele Leigertwood and Marc Nygaard to injury in the same game.
Leigertwood will see a specialist after suffering a broken nose, while Nygaard will have a scan on a hamstring problem.
