Captain Mark Hudson and regular central defensive partner Ben Turner are both doubts for the reunion with former Bluebirds boss Dave Jones at Hillsborough.
Hudson had to be substituted in the 1-1 draw with Leicester on Tuesday with an ankle injury and is rated `doubtful' while Turner also sustained an ankle problem in the build-up to the match and is said to be `touch and go'.
The off-form Bluebirds finished the match with Matthew Connolly and Ben Nugent in central defence and they could link up again with Kevin McNaughton replacing Connolly at right-back.
Cardiff's lead at the top of the table has been cut to four points after just one win in their last five matches.
