Mark Hughes has revealed that Armand Traore could be out for a couple of weeks after suffering a hamstring injury against Liverpool.
Traore was replaced at half-time of Wednesday's match following a clash with Charlie Adam and had to watch from the touchline as Queens Park Rangers came from behind to win 3-2.
The extent of the damage has now been revealed and he will sit out Saturday's game at Sunderland.
The left-back could also be set to miss the home fixture against Arsenal on 31st March ahead of a possible return at Manchester United on 8th April.
"Armand Traore is unavailable," Hughes said. "He got injured before half-time in a clash with Charlie Adam.
"Unfortunately, he hasn't made it. He has got a grade one hamstring injury so he could be out for a couple of weeks."
Clint Hill, who missed the Liverpool victory with a back complaint, is back in contention to face Sunderland.
