Pawel Wszolek faces a fitness test ahead of QPR’s game against Hull City, while Joel Lynch has been ruled out.
Wszolek went off during the first half of this week’s defeat at Norwich with what Rangers have since established is a back problem.
Manager Ian Holloway admitted after the game at Carrow Road that he had been unable to ascertain the nature of Wszolek’s injury.
The Pole looks very doubtful for Saturday’s game and Lynch will definitely be sidelined after picking up a hamstring injury.
Lynch was also taken off at Norwich, where Rangers lost 2-0.
QPR say Yeni Ngbakoto and Idrissa Sylla will also be assessed ahead of this weekend’s match.
Ngbakoto has been nursing an ankle problem, while striker Sylla took a knock to the head during the recent EFL Cup win against Northampton.
