United will probably be without midfielder Nick Montgomery (ankle ligaments) who picked up a serious injury against Burnley in the 4-2 other a week ago.
Warnock will also be checking on the fitness of Peter Ndlovu (ear infection) and Stuart McCall (ankle), but they too are likely not to be involved against the Rams.
Derby, on the other hand will defiantly be
without on loan striker Tommy Mooney. Mooney did not complete his three month loan spell at Bramall Lane so the Blades were allowed to retain his registration and therefore were able to stop the Rams from playing Mooney against United.
A doubt is former Blade Lee Morris, who has recently been suffering with a bout of sciatica and will have a late fitness test, while star player Izale McLeod is likely to play through the pain of an ankle injury.
Georgian International Giorgi Kinkladze has suffered with back pain, but the former Blades target is probable to make the bench, though Adam Murray will not play due to a chest infection. Possible Starting Line-Ups:Blades Rams Kenny Grant Jagielka Mills Murphy Barton Page Elliot Kozluk Boertein Morrison Burley Javary Lee Brown Bolder Tonge Ravinelli Windass Hunt Kabba McLeod
Prediction: Sheffield United 1-0 Derby County
