Pompey will try to reach the final of the Checkatrade Trophy for the first time – including any of the competition’s previous guises – tonight.
But first they must see off a Bury team who are full of confidence as they try to secure automatic promotion to League One.
Ryan Lowe’s side sit second in the standings and are just two points behind leaders Lincoln – who have a game in hand – in the battle for the title.
While Wembley will be a welcome reward for both sides, the main priority for the hosts will be bouncing back to the third tier at the first attempt following last season’s relegation.
The Shakers are unbeaten in 12 matches in all competitions and have won nine of those fixtures, including a 3-1 victory over Oldham at the weekend.
Their path to this stage started with finishing as runners-up to Rochdale in Northern Group B, which also included Leicester U21s and Fleetwood.
Bury have since seen off Mansfield, Accrington and Oxford, and are also trying to reach the final for the first time.
The sides have never previously met in this competition, but Pompey were beaten 1-0 on their last trip to Gigg Lane in the penultimate game of last season.
Lloyd Isgrove, Bryn Morris and the injured Andy Cannon are all cup-tied, having featured in the competition this season for their previous clubs.
Pompey will also be without Jack Whatmough (knee), while there is a doubt over Omar Bogle (hamstring), but Nathan Thompson is available again.
Jermaine Beckford (knee) is out for the hosts and Stephen Dawson (foot) is struggling, although Caolan Lavery could feature against his former club,
HEAD TO HEAD
Pompey: 12 wins
Bury: 13 wins
At Gigg Lane
Pompey: 3 wins
Bury: 10 wins
Seats are no longer available to buy from Pompey, but can be purchased at the Gigg Lane ticket office or from the cash turnstiles this evening.
The game has been selected for live television coverage, so there will be no live video on iFollow for overseas subscribers.
