Jack Robinson and Jake Bidwell are struggling with injuries ahead of QPR’s trip to face Sheffield United.
Both players were hurt during the home win against Bolton at the weekend and face fitness tests before Tuesday’s game at Bramall Lane.
Robinson has a toe injury, while Bidwell is nursing a shoulder problem.
James Perch has been passed fit to return to the squad and could well play if either Robinson or Bidwell miss out.
Idrissa Sylla is still unavailable but manager Ian Holloway has said the striker is close returning.
