Warnock could include Warnock
Leeds are expected to include new signing Stephen Warnock in their squad for the home clash with leaders Cardiff.
But another new recruit, Steve Morison, must wait for his debut after arriving from Norwich in a swap deal with Luciano Becchio as he is struggling with a thigh injury.
Leeds agreed a permanent deal with Aston Villa for Warnock on transfer deadline day and manager Neil Warnock must decide whether to include him from the start.
Warnock must also decide whether to recall teenage loanee Ross Barkley to his starting line-up. The Everton midfielder was not given permission to play in last Sunday's FA Cup win over Tottenham.
Paddy Kenny will be hoping to return after being replaced by Jamie Ashdown against Spurs while midfielders Michael Tonge and David Norris, plus defender Jason Pearce and striker Davide Somma are all aiming to feature.
New signing Fraizer Campbell is set to make his Cardiff debut.
The 25-year-old striker joined from Sunderland for an undisclosed fee last week.
Defender Simon Lappin is also available after signing a permanent deal with the club following his departure from Norwich.
Craig Bellamy, who returned to the Wales squad this week, missed the victory at Blackpool with a stomach bug but is fully fit and ready to feature against Neil Warnock's men, who knocked Tottenham out of the FA Cup on Sunday.
This clash is the npower Championship leaders' first match for two weeks due to their cup exit at the hands of Macclesfield and manager Malky Mackay took his side away for warm-weather training in Dubai.
The only long-term injury absentee for Mackay is Nicky Maynard, who is likely to miss the rest of the season.
