Pompey fans have snapped up more than 2,500 tickets for Saturday’s match at Peterborough.
They are no longer on sale from the Blues, but do not worry if you have yet to secure your seat for top-of-the-table contest.
Peterborough are still selling tickets to visiting supporters via their eticketing site (registration is required).
Pompey fans will also be able to purchase seats in the Main Stand from the Peterborough ticket office from 10am up until midday on Saturday.
Please note that the price for adult tickets increases to £28 if bought on the day of the game.
Supporters collecting tickets should visit the booth next to the Main Stand away turnstiles.
