Pompey have won two of the past three away games to reignite a play-off push.
But now they will be hoping to get their home form back on track by beating Blackpool this weekend.
A run of one victory from 14 games saw the Seasiders suffer an alarming drop down the League One table.
They arrested the slide with an impressive 2-0 triumph at high-flying Wigan recently, though, and go into Saturday’s contest on a four-match unbeaten run.
But Gary Bowyer’s men – who were promoted via the play-offs last term – are still only three points above the drop zone.
And they will arrive at Fratton Park having collected three points on the road just four times all season.
Pompey emerged 3-2 victors when the sides clashed at Bloomfield Road earlier in the campaign, courtesy of a second half goal-fest.
And you have to go all the way back to 1971 to find the last time the Blues were beaten by the Seasiders on the south coast.
Kal Naismith has recovered from a groin injury, but Gareth Evans and Brett Pitman are both still sidelined with hamstring problems.
Nathan Thompson serves the second game of a four-match ban following his red card at Southend last Saturday.
Pompey are also still without the injured trio of Stephen Henderson (thigh), Stuart O’Keefe (groin) and Danny Rose (leg).
Blackpool will be without Callum Cooke (heel), Mark Cullen (hamstring) and Jim McAlister (leg), but top Kyle Vassell has returned to fitness.
