Doncaster goalkeeper Neil Sullivan and midfielder John Oster will return to Sean O'Driscoll's squad.
Sullivan has been struggling with a knee/shin injury that has kept him out of the last five matches and O'Driscoll must decide whether to include him in the starting line-up or retain deputy Gary Woods.
Oster has been sidelined for two matches due to a calf injury but returned to full training this week and could go straight back into the starting line-up.
Striker Paul Keegan, who only arrived at the Keepmoat Stadium in January, has been ruled out for the rest of the season following surgery to resolve knee cartilage trouble, but O'Driscoll has no other new injury or suspension problems.
Leading goalscorer Billy Sharp (groin) and defenders Joe Mills (foot), James Chambers (hamstring), James O'Connor (foot) and Mustapha Dumbuya (knee) remain sidelined.
Wayne Routledge is the only fresh injury concern for QPR boss Neil Warnock ahead of the clash.
The on-loan winger picked up an ankle injury on Monday and only returned to training on Thursday.
Warnock could make one unforced change, with Danny Shittu in line to replace Kaspars Gorkss at the heart of the Hoops' defence following his return from a one-match ban.
Fellow defender Fitz Hall looks set to shake off the knock which he picked up in the 2-1 victory over former club Crystal Palace last weekend.
Hall appeared to be limping during the London derby against the Eagles but Warnock expects him to start at the Keepmoat Stadium.
Rangers have lost on their last three visits to Doncaster without finding the back of the net.
