The Pilgrims are set to host the Posh (kick-off 7.00pm) in a 120-minute contest at the Jakemans Community Stadium.
Both teams are expected to field two different XIs, with the new campaign only two-and-a-half weeks away.
With the exception of injured defender Kieran Coates, United are expected to utilise their full squad.
Tickets are on sale here – with contactless payments accepted on the turnstiles.
In addition to terracing in the East Stand (Away) section, Posh supporters can also purchase seats in Block A of the Acorn Taxis (West) Stand.
