Ticket sales for Norwich City's home clash with Birmingham City, due to begin on Monday, January 9, have been postponed.
Birmingham's FA Cup clash with Forest Green Rovers this weekend was called off, meaning it is as yet unknown whether the Blues will be in the next round of the competition.
The fourth round games are scheduled for the same weekend as the Canaries' Sky Bet Championship meeting with Birmingham at the end of this month.
Tickets for the Burnley fixture on Saturday, February 4, will still go on sale as normal tomorrow.
Further details will be made available to supporters when the re-fixed third round game has been played.
