SHAUN Williams will miss Saturday's match at Elland Road through suspension.
The midfielder picked up his tenth booking of the season against Charlton last time out and subsequently serves a two-match ban, starting tomorrow.
Midfielder Jimmy Abdou is likely to replace Williams' in the matchday squad of 18.
Scott Malone has trained fully this week since returning to the bench for the goalless draw with the Addicks after a hip problem and could start against Leeds.
The terms of Steve Morison's loan move to Millwall stipulate that he cannot play against his parent club, so Stefan Maierhofer or John Marquis look set to come into the side.
DJ Campbell resumed training on Thursday following a hamstring strain and could feature, but Jermaine Easter, Nicky Bailey and Danny Shittu are definitely out.
Fede Bessone (ankle), Lee Martin (knee) and Richard Chaplow (Achilles) are doubts.
For Leeds, Rodolph Austin is hoping to shake off a knock but Jimmy Kebe (hamstring) is out.
