Several first team players will feature in a Pompey XI friendly at Bognor on Tuesday evening (7.45pm kick-off).
Luke McGee, Christian Burgess, Adam May and Louis Dennis are all expected to start at Nyewood Lane.
Third year scholars Matt Casey and Dan Smith – who have been given squad numbers ahead of the 2018/18 campaign – will also be involved.
Pompey have a first team friendly behind closed doors at Brighton’s training ground earlier in the day.
Tickets for the Bognor game can be bought on the turnstiles, priced £6 for adults and £3 for under 18s.
