There will be a feeling of déjà vu for many Pompey fans, as they prepare to make the long trip north to Sunderland.
It was just two weeks ago that the sides played out a 1-1 draw at the Stadium of Light, with Jamal Lowe cancelling out Tom Flanagan’s opener.
Now the Blues are heading back to the north-east for the first leg of the play-offs (7.30pm kick-off), with a spot at Wembley up for grabs.
The two sides have already been to the national stadium this season, of course, with Kenny Jackett’s side emerging triumphant from a penalty shoot-out in the Checkatrade Trophy final.
And Pompey also came out on top in a league meeting at Fratton Park just before Christmas, as Gareth Evans, Ronan Curtis and Ben Thompson all scored in a 3-1 win.
There will be a slight feeling of frustration in both camps about missing out on automatic promotion to the Championship.
They are only facing off at this stage because a late goal for Charlton in their final day rout of Rochdale saw them snatch third spot from the Blues on goal difference.
The Fratton faithful are looking for their side to secure Championship football for the first time since 2012.
But the Black Cats are aiming for an instant return, having suffered a second successive relegation after finishing rock bottom last term.
Pompey are close to having a fully-fit squad to choose from, with Dion Donohue (groin) and Jack Whatmough (knee) the only absentees.
Sunderland have no major injury concerns, with Aiden McGeady returning to training after recovering from a broken bone in his foot.
