QPR will be without Mikele Leigertwood and have major doubts over Hogan Ephraim and Marcus Bent for the visit of Doncaster.
Leigertwood will have to serve the final game of his three-match ban after Tuesday night's clash with Watford was postponed.
Winger Ephraim has an ankle injury and on-loan Birmingham striker Bent is struggling with a hamstring problem, with neither likely to be available.
Rangers are still without long-term knee-injury victims Martin Rowlands and Gavin Mahon.
Rowlands' injury will keep him out for the rest of the season but the club hope fellow midfielder Mahon will be pushing for a return by April.
Young striker Antonio German could be called up to make his full debut.
Doncaster will assess the fitness of Gareth Roberts.
The defender is back in training following a knee problem but it remains to be seen whether or not he will be included.
Martin Woods (groin) has also resumed training, but the game at Loftus Road is likely to come too soon for the midfielder.
On-loan defender Jason Shackell (hernia) will again miss out after returning to parent club Wolves to have his injury assessed, so Sam Hird is will continue in his absence.
Adam Lockwood is back in light training following a foot problem, but Byron Webster remains sidelined with a broken metatarsal.
Rovers will be looking to continue their recent good form after back-to-back victories over Nottingham Forest and Sheffield Wednesday.
