Pompey have been hovering just outside the League One play-off places for a number of weeks now.
But attention switches away from a battle for promotion this weekend, as they make the long trip north to face Fleetwood in the third round of the Emirates FA Cup (5.31pm kick-off).
They have yet to face their opponents from the same division this term, with November’s scheduled league contest postponed because of international commitments.
It means that this clash will be the first of three meetings taking place in the space of a little over nine weeks.
There could be even more if a replay is required, while both sides also remain in the Leasing.com Trophy.
The Cod Army are currently one point – and two places – above the Blues in the League One standings, having played one game fewer.
Joey Barton’s side reached this stage of the famous old competition with away victories at Barnet and Crawley, but have never made it to the fourth round.
There have been only six previous competitive contests between the teams and Pompey have won each of the past four encounters with an aggregate score of 12-4.
The most recent one – which occurred just over a year ago – saw the Blues battle from behind before ultimately securing a comfortable 5-2 triumph.
Pompey could hand a debut to left-back Steve Seddon following his arrival on loan from Birmingham.
Ryan Williams is still absent after injuring his groin in the Boxing Day victory over Wycombe at Fratton Park.
Ross McCrorie (hamstring), Lee Brown (Achilles) and Brandon Haunstrup (meniscus) are also sidelined.
Bryn Morris (groin) is still in the treatment room, while Jack Whatmough is not yet ready for selection following his knee problem.
Fleetwood will be without midfielder Jordan Rossiter (knee), while Peter Clarke, Jimmy Dunne and Ashley Hunter have all departed in the past few days.
