Geoff Cameron is available for QPR after he missed the loss at Blackburn with a hamstring injury, but is in contention to return.
Striker Tomer Hemed is a doubt with a groin problem which saw him miss the same game.
Brentford could select the same side which earned a 2-0 win over Millwall, ending a nine-game winless sequence.
Lewis Macleod could be available again after a slight hamstring problem, but fellow midfielder Kamohelo Mokotjo has a calf injury which will see him miss four to six weeks.
