Andrew Davies (knee), Luke Oliver (Achilles) and Garry Thompson (knee) are all expected to miss out for Bradford.
However, the Bantams have few other injury worries as they prepare to host Premier League opposition yet again this season.
Paul Lambert, meanwhile, will have to juggle his squad as the Villans have a number of injury problems to contend with across several positions.
Marc Albrighton is doubtful for the clash after injuring his foot against Ipswich but could make the squad whilst Richard Dunne (groin) and Stiliyan Petrov (leukaemia) have no set return dates.
Ron Vlaar (calf) and Nathan Baker (hamstring) should both still be out while long-term absentee Gary Gardner (knee) will be absent until May.
Neither side has any suspensions for the game.
