Pompey will be trying to play the role of party-poopers when they host high-flying Wigan this evening (7.45pm kick-off).
The visitors need just a single point to mathematically secure their place in the Championship for next season.
And they could even claim the title if they can better second-placed Rotherham’s result at Sunderland.
It would complete a remarkable turnaround for the Latics, who narrowly avoided relegation into the basement last season, having recovered from financial turmoil.
There are plenty of familiar faces in both camps, with academy graduate Jack Whatmough and former skipper Tom Naylor returning to the south coast.
They are managed by Leam Richardson, who was assistant to Paul Cook when the Blues dramatically claimed the 2016/17 League Two title, while ex-keeper Darryl Flahavan is on his coaching staff.
Michael Jacobs twice won promotion from this level with Wigan and fellow Pompey midfielder Ryan Tunnicliffe had a couple of loan spells at the DW Stadium.
Richardson’s men won 1-0 when the sides met in the north-west earlier in the campaign and triumphed by the same scoreline on their most recent visit to Fratton Park.
Kieron Freeman (ankle), Reeco Hackett (knee) Denver Hume (back) and Jayden Reid (knee) are all still sidelined for Pompey.
But Connor Ogilvie could feature despite going off with a tight hamstring against Gillingham on Saturday.
Wigan are expected to be without Tom Bayliss (groin), James McClean (knee) and Curtis Tilt (hamstring), as well as Charlie Wyke, who continues his recovery after suffering a cardiac arrest in November.
