Tickets for Pompey's League One visit to Oxford have now sold out.
It means that Danny Cowley's side will be backed by more than 1,700 fans at the Kassam Stadium on Saturday, February 5 (3pm kick-off).
Supporters who purchased concession tickets are advised to bring proof of age identification with them to the game.
Supporters are encouraged to take a lateral flow test at least 24 hours before the game and should not attend if they display any symptoms or have been told to self-isolate.
It is strongly recommended that face coverings are worn in the concourse areas, while supporters should santise their hands before entering the ground using the facilities provided.
There is free car parking for 2,000 vehicles on a first come, first served basis at the stadium, while free parking is also available along Grenoble Road, which is adjacent to the ground.
