With Josh Cullen having played for Ireland U21s on Saturday afternoon and Nathaniel Knight-Percival ruled out after picking up a cut to the face in training on Friday, both Billy Clarke and Kevin Toner are named in McCall's starting XI.
Cullen has travelled with the squad but he was not been risked following his efforts for Ireland just 24 hours earlier.
Nicky Law is also not involved due to the same knee injury that has also ruled him out of City's previous four fixtures.
For Toner, it will be the Irish defender's first outing in City colours following his loan move from Aston Villa on transfer deadline day at the end of January.
City's third change for the Sunday lunchtime encounter with the Iron sees Alex Jones replace Jordy Hiwula.
Hiwula is named on the Bantams' bench, along with young professionals Jacob Hanson and Daniel Pybus.
Colin Doyle keeps his place in City's side after temporarily returning from international duty with the Ireland senior side on Saturday.
