Season ticket holders have until 4pm on Saturday to claim their usual seats for the replay next Tuesday (ko - 7.45pm).
Season ticket holders are also advised that they can now book their own seats online using a new e-ticketing system set up by Synchto. Usernames and passwords were sent out to all season ticket holders before Christmas.
Season ticket holders in the South Stand will not be able to claim their usual seats because Nuneaton have taken an allocation of 5,000 tickets.
Tickets are also on general sale for some seats not used by season ticket holders. All tickets are priced at £10 for adults and £5 for concessions.
