The Frenchman, who missed Saturday's goalless draw at home to Norwich, suffered a groin injury in training and will know the full extent of his injury early next week.
Manager Harry Redknapp said: "He tore a groin muscle in training on Thursday and I have no idea at the moment how long he will be out.
"It was in the last minute of training, and he just struck a ball and felt it go.
"We will have to see how he is on Sunday and Monday, and then take it from there."
The 26-year-old moved to Loftus Road from Marseille just over two weeks ago.
