Sunderland's upcoming Sky Bet Championship game at Birmingham City will be re-arranged following the Blues' progression in the Emirates FA Cup.
City beat Burton Albion 1-0 to move on to the Fourth Round, with ties to be played on the weekend of 27th/28th January.
Therefore, the Black Cats' trip to the Midlands - originally scheduled for the 27th - will now be rescheduled.
A new date will be announced in due course.
