Next Tuesday is likely but I wouldn`t rule out the game being scheduled for Monday as this might fit in more conveniently for their travel plans throughout next week.
If they play Tuesday it will mean a very busy travel schedule: traveling on Monday, staying Monday night, then not arriving back home until well into Wednesday morning. They would then be back on the bus headed north the following day, Thursday for their over-nighter prior to facing Fleetwood. If the replay is next week, whether Monday or Tuesday, travel will catch up with them. Maybe they should fly !
