A club spokesman said: "There is obviously a lot of interest in the Leeds game and we have been given an initial allocation of 2,400.
"At this stage we aren’t expecting that there will be a demand for any more than that.
"If there is a rush next week, there is the option to take a further ticket delivery from Leeds United."
Supporters Club spokesman Nigel Bennett said: "When the draw was made I thought that we would probably take a couple of thousand to Leeds.
"I’m sure that’s more than enough to make some noise and really get behind the lads.
"It should be a great night out for everyone.
"I think we travel more in hope than expectation but if we can get another decent result at Barnsley on Saturday and with Leeds’ confidence clearly not that high at the moment, who knows?
"But whatever happens, let’s enjoy it."
Tickets for game are priced as follows: £10 (adults) and £5 (concessions). A family ticket (two adults and two under 16s) can be purchased for £25.
