Luke Varney starts on the bench with Lloyd Sam and Hameur Bouazza on the flanks and Jose Semedo partners Nicky Bailey in the centre of midfield.
The defence remains unchanged and despite reports linking Alan Pardew's side with a move for Blackburn and former Addicks keeper Jason Brown, Nicky Weaver remains in goal after his two mistakes in the 3-2 defeat to Birmingham last weekend.
Possible side for Sheffield United: Weaver, Moutaouakil, Hudson(c), Primus, Youga, Sam, Semedo, Bailey, Bouazza, Gray, Waghorn
Subs: Elliot, Cranie, Varney, Holland, Todorov
