Wolves striker Steven Fletcher is a doubt as he battles to recover from a groin problem.
The Scot picked up the injury in last weekend's 2-0 defeat by Tottenham and it was initially feared he could be sidelined for a spell but boss Mick McCarthy is hopeful he will be available.
Winger Stephen Hunt and defender Kevin Foley have both missed training this week with ankle niggles but McCarthy is confident they, too, will be fit for the match.
QPR manager Neil Warnock was expecting no fresh injury concerns ahead of the game.
Rangers' new signings all came through Monday night's goalless draw with Newcastle relatively unscathed and should be available again for the Molineux clash.
Kieron Dyer (foot), Jamie Mackie (leg) and Rob Hulse (knee) remain sidelined.
