Todd makes defensive switch
Influential midfielder Marc Bridge-Wilkinson, who missed last Saturday's 1-1 draw with Yeovil, is struggling to be fit in time.
Tom Kearney joins the subs' bench, but striker Steve Claridge misses out.
Last month, City recorded their first win in all cup competitions since 2001 by thrashing Rochdale 5-0.
Bantams squad (probable): Howarth, Edghill, Wetherall, Bower, Emanuel, Muirhead, Schumacher, Crooks, Petta, Windass, Cooke, Stewart, Swift, Holloway, Kearney, Cadamarteri.
