City's FA Youth Cup third round game against Watford has been postponed.
The fixture was due to be played on Friday but has been rearranged with the LNER Stadium pitch unplayable following temperatures of -6C on Wednesday evening.
The forecast is for similar temperatures overnight on Thursday and, after an inspection by a referee, it was agreed the game could not take place on the original date.
Tickets will remain valid for the rearranged fixture once a new date has been confirmed.
