Boss Neil Warnock will check on Lee Cook ahead of QPR's home game against Plymouth.
Winger Cook was ruled out of Saturday's win over West Brom having been suffering all week with a cold.
But Warnock may opt to stick with the starting line-up which picked up an impressive 3-1 victory in his first game in charge.
That would mean no place for striker Marcus Bent, who missed out at the weekend as Rangers fielded the maximum five loanees allowed in a matchday squad.
Midfield duo Martin Rowlands and Gavin Mahon remain long-term absentees with knee injuries.
Rowlands will not figure again this season but Mahon hopes to be able to play some part before the end of the campaign.
Plymouth midfielder Craig Noone is an injury doubt.
Noone was in top form in Saturday's 1-1 draw with Preston following his half-time introduction but, having cannoned a shot off the crossbar in the 89th minute, the livewire winger suffered a stoppage-time leg injury.
Fellow midfielder Chris Clark is also an injury doubt following his 54th-minute substitution.
Head coach Paul Mariner explained: "The whole of his right side was tight."
With central defender Reda Johnson (groin) already ruled out, Mariner may have to make further changes to his starting XI, which included debutant Richard Eckersley - on loan from Burnley - on Saturday.
Eckersley will keep his place at right-back with Karl Duguid switching to central midfield.
On the flanks, Mariner can choose from Luke Summerfield - recalled on Saturday - Yannick Bolasie or on-loan Blackburn playmaker Alan Judge should Noone and Clark fail to pass fit.
