This match could come down to how much Birmingham would appreciate an extra fixture in their season, as they look nervously over their shoulder towards the Championship relegation zone.
They are five points clear of it as things stand, having won just one of their last seven league games. They looked set to improve on that record at the weekend, only for Adam Hammill’s goal in the last minute denying Lee Clark the win over his former side Huddersfield.
Leeds sit five points off the Championship play-off places, although their form is not top-rate either. A 2-0 defeat to Barnsley on Saturday was their third loss in four Championship games. Neil Warnock is sure to demand improvement against Birmingham, with a home tie against Tottenham on offer to the winners of the replay.
