Pompey’s final scheduled midweek away fixture of the season sees them make the trip to London Road to face Peterborough.
The sides are closely matched in the table, with the Blues a single place and point above their 11th-placed hosts.
Grant McCann’s Posh outfit came roaring out of the traps at the start of the season, winning their opening four League One fixtures.
Victories have not arrived quite so frequently since, however, with just three to celebrate since the start of September.
But there has been some success in other competitions, with progress to the knockout stages of the Checkatrade Trophy and a 5-0 rout of Tranmere setting up a game at Woking in the FA Cup.
United fans will now be searching for some progress from last term, when they finished 11th and were only marginally closer to the play-off spots than the drop zone.
Pompey fans can feel confident making the trip north, though, as their side have only ever been beaten once at Peterborough.
Their last visit was for a Championship clash in January 2012, with Erik Huseklepp’s brace and a Jason Pearce header securing a 3-0 triumph.
Pompey have no new injury concerns, but are still without the injured trio of Milan Lalkovic (Achilles), Damien McCrory (knee) and Jack Whatmough (knee).
The hosts are also almost at full strength, with only Junior Morias (thigh) and Liam Shephard (groin) on the sidelines.
