City's visit of Leyton Orient next year will now take place on Tuesday February 1, and get underway from 7.45pm.
Originally set to take place on Saturday January 8 (3.00pm), the clash has been rearranged as a result of Orient's participation in the third round of the Emirates FA Cup.
The Utilita Energy Stadium encounter will now fall between the Bantams' visit of Crawley Town on Saturday January 29, and trip to Harrogate Town on Saturday February 5.
Tickets for the rearranged fixture will be available to purchase in due course, via the club's official ticketing website.
