Cardiff midfielder Gavin Rae has been ruled out for the remainder of the season ahead of the Bluebirds` home clash against Reading.
The 32-year-old requires ankle surgery having ruptured tendons and is likely to be sidelined for around 12 weeks.
The news comes following the timely return of Joe Ledley after a double hip operation, with the Wales international playing his first full match in just over two months as the Bluebirds held Nottingham Forest to a goalless draw on Monday.
However, fellow midfielders Peter Whittingham and Chris Burke remain doubts to face the Royals due to muscle injuries and will both undergo late fitness tests, along with defender Kevin McNaughton.
Captain Mark Hudson is back in full training after a lengthy absence following ankle surgery of his own and may play a part, although manager Dave Jones could opt to give him another week of training before throwing him back in at QPR next Saturday.
Reading will be without Matt Mills. The Royals skipper was able to play in the 3-0 win over Coventry on Monday after appealing the red card he was shown at Ipswich last Saturday but begins a four-match ban in Wales after the FA rejected his appeal.
Midfielder Jem Karacan was handed a rare start against Chris Coleman`s side but came off with a dead leg and is a doubt while Brian Howard is hopeful of a return after missing out with a neck injury.
Top scorer Gylfi Sigurdsson was granted a rest on Monday but should return to play behind the striker but manager Brian McDermott remains without Ivar Ingimarsson (hamstring), Czech Republic midfielder Marek Matejovsky (stomach) and Kalifa Cisse (thigh).
Noel Hunt and Chris Armstrong remain long-term absentees with their knee injuries.
