City look to end a three match losing run when the face Q.P.R. at Loftus Rd today.
The hosts will monitor the fitness of Grant Hall ahead of the clash with Cardiff.
Hall made his first start since April following a lengthy battle with a knee injury at Millwall on Friday night and appeared to be struggling towards the end of the game.
"The nature of the injury he's had for the last six or seven months is one where we're all hoping that he doesn't get a recurrence of the tendinitis," boss Ian Holloway said after the 1-0 loss to the Lions. "We'll have to wait and see."
Josh Scowen is available after suspension, while Luke Freeman returned from a ban at The Den and should keep his place. Jack Robinson missed out through illness on Friday night but may yet recover in time to face the Bluebirds.
Cardiff winger Junior Hoilett should return against the club he made over 120 appearances for between 2012 and 2016.
Hoilett dropped to the bench for Friday's home defeat to Preston after a bout of illness but came on as a second-half substitute.
Bluebirds boss Neil Warnock is considering changes after three successive defeats, but his options are limited by a heavy injury list.
"I know my 11 starters for New Year’s Day. I’m going to try something different." said Warnock.
Aron Gunnarsson (ankle), Sean Morrison (groin), Danny Ward (knee), Kadeem Harris (knee) and Jazz Richards are all out, while Craig Bryson and Joe Bennett face fitness tests after picking up festive knocks.
QPR have won 12 of their last 16 home league matches against Cardiff (D1 L3), winning 2-1 last season.
The Bluebirds' last league double over QPR came in the 2007/08 season - they won 2-1 against the Hoops earlier this season.
QPR are winless in four home league games (D2 L2), their worst run since Ian Holloway returned to the club in November 2016 - including his first spell in charge, the Hoops have never gone five home league matches without a win under Holloway.
Neil Warnock hasn't won away from home at Loftus Road since December 2007, when his Crystal Palace side won 2-1 against a QPR team managed by Luigi De Canio.
Ian Holloway has won five of his last six home league meetings with Warnock (D1) since losing 1-0 during his first spell as QPR boss against Warnock's Sheffield United in August 2004.
Sol Bamba has found the net in both Championship appearances against QPR for Cardiff, scoring twice.
