This fixture was initially scheduled to be an all-ticket game for City fans but the Blades will now allow Bradford supporters to pay on the day.
Match ticket prices will increase slightly, however, from the original pre-match admission prices.

Ticket prices on the day will be:
Adults - £21.50
Senior & disabled supporters - £14.00
Student & Young Adults - £12.00
Juniors - £8.00
