De Vos currentley looks doubtful with a thigh injury sustained in the 5-1 midweek thrashing of Sheffield United, however it will be left until the last possible moment before making a decision on if he will be involved in the match in some shape or form.
With Canadian De Vos rated worse than 50-50 to be involved by manager Joe Royle yesterday, Antonio Murray and Scott Mitchell have been added to the 16 that made up the starting eleven and five substitutes on Tuesday.
Kelvin Davis is now fully fit again and Town boss Joe Royle must decide whether to reinstate the former Wimbledon keeper, or keep faith with Welsh Under 21 international Lewis Price who has impressed in his absence.
Full Squad: Bent, Bowditch, Collins, Counago, Davis, De Vos, Diallo, Horlock, Kuqi, Magilton, Miller, Mitchell, Murray, Naylor, Price, Richards, Westlake, Wilnis.
