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.
