QPR will give a fitness test to Wayne Routledge, who picked up an ankle injury in training this week.
Fitz Hall seems to have shaken off a knock, while Dan Shittu is available again after serving a suspension.
MATCH PREVIEW QPR are overwhelmingly confident they will not be docked points after recently being hit with Football Association charges relating to their signing of Argentine midfielder Alejandro Faurlin.
And they can head to the Keepmoat Stadium with plenty of confidence given their recent form and injury-hit Doncaster's slide towards a relegation battle.
Rangers, who have not been out of the automatic promotion places all season, are seven points clear at the top and 10 clear of third-placed Swansea. Another win on Saturday would be their fifth victory in six matches, and their 21st of the season.
Doncaster were part of the promotion race themselves at the end of 2010. They were one place outside of the play-off zone in December, but are now alarmingly close to the drop zone after a run of only one win in 10 matches.
MATCH FACTS Head-to-head
• Doncaster and QPR have each won six of their 13 previous league matches between these clubs.
• QPR won 2-0 on the club's first visit to Rovers, in April 1951, but have only taken a total of one point from their five subsequent trips.
• Having conceded 66 goals in 37 Championship games, Doncaster have the joint worst defensive record in the division.
• Rovers have picked up only two points from the last possible 12 at home.
• A win would give the Yorkshire club their 300th league point under manager Sean O'Driscoll.
Queens Park Rangers
• QPR boast the best defensive record in the Championship, having conceded fewer goals (23) and kept more clean sheets (20) than any other team.
• They have won 14 matches this season by two or more goals.
• A goal for Tommy Smith would be the 100th of the forward's career.
