The fixture will now take place at St. Andrew's on Tuesday 7 January, 2014 and will kick-off at 7.45pm.
The change has been confirmed by the FA after last night's second round replay between Crawley and Bristol was called off towards the end of the second half because of a water-logged pitch.
Blues supporters that have already purchased a ticket for the original date on 4 January will be able to use those tickets on the rearranged date. Should they not be able to make the new date they can claim a refund on their ticket by contacting the Blues ticket office.
