QPR forward Karamoko Dembele will be out until February after undergoing knee surgery.
The 21-year-old, who is on loan from French side Brest, had scored one goal in 10 Championship starts for the R’s.
He has not played since the 1-1 draw with Coventry City on 22 October and is the latest Rangers player to be forced out with injury.
Michael Frey, Jake Clarke-Salter and Ilias Chair are not expected to return until early next month.
But QPR have been boosted by the news that Joe Walsh, Morgan Fox and Kenneth Paal are available to face Stoke City this weekend while Jack Colback could feature next week.
