Saturday's Sky Bet League One game against Burton Albion has been postponed due to a frozen pitch after colder than forecast temperatures overnight.
Match official Marc Edwards inspected the playing surface on Saturday morning and, with temperatures forecast to remain below freezing until the afternoon, felt the pitch was unlikely to be playable in time for the match.
City took steps to protect the playing surface, with frost covers and lighting rigs in place since the start of the week - with an EFL official deeming the pitch playable on Friday afternoon.
Tickets will remain valid for the rearranged date which will be announced in due course.
