It is fourth versus fifth at the Wham Stadium tonight as Accrington and Pompey both look to close the gap on the automatic promotion places.
A win for the Blues would leave them six points behind third-placed Plymouth, who still have to visit Fratton Park this season.
This match was originally scheduled to be played in January, but a frozen pitch meant it was postponed a few hours before kick-off.
It was one of a number of Stanley games to have fallen victim to the weather this season, leaving League Two’s surprise package playing catch up.
A hectic schedule has perhaps hindered John Coleman’s side in recent weeks, as they have taken just two points from their last three games.
But Accrington were unfortunate not to beat AFC Wimbledon at the weekend, with referee Trevor Kettle controversially blowing for half-time, just before Billy Kee put the ball in the back of the net.
They have already visited Fratton Park twice this season, drawing 0-0 in the league before being defeated 1-0 in the second round of the FA Cup.
And Stanley will welcome a host of familiar faces tonight, with Blues boss Paul Cook and assistant Leam Richardson, as well as midfielders Gary Roberts and Kal Naismith, all returning to their former club.
Pompey are close to having a clean bill of health, with only goalkeeper Brian Murphy (calf) currently sidelined.
Accrington are without Terry Gornell (ankle) Josh Windass (hernia), Dean Winnard (chest) and Joe Wright (knee).
Former Blues utility man Rommy Boco will not feature because of a gentlemen’s agreement between the sides.
Stanley are waiting to hear whether they have been successful in appealing goalkeeper Ross Etheridge’s red card against AFC Wimbledon at the weekend.
