Pompey will search for just a second away league victory of the season when they face Bristol Rovers on Saturday.
Kenny Jackett’s side remain unbeaten on home soil, but have collected only four points on their travels.
Their opponents are sitting in 11th position and with five more points, albeit having played two games more.
But Graham Coughlan’s men go into the contest on the back of successive 2-0 defeats to Doncaster and Bolton, becoming the first team to lose to the latter this season.
That brought to an end an impressive eight-match unbeaten run in all competitions, which included four league triumphs.
The Pirates are aiming to improve on last term’s 15th-placed finish, with just four points separating them from the drop zone.
They are competing at this level for a fourth consecutive campaign following their dramatic final day promotion in 2016.
Pompey won 2-1 in last season’s corresponding fixture, with Ronan Curtis netting a late winner after Chris Lines’ penalty had cancelled out Gareth Evans’ opener.
Pompey have no new injury concerns ahead of the weekend, but Brett Pitman is still a major doubt with a groin strain.
Oli Hawkins (foot), Bryn Morris (groin) and Jack Whatmough (knee) are definitely all missing for the Blues.
Bristol Rovers will be without their top scorer Jonson Clarke-Harris (calf), while former Fratton loanee Tareiq Holmes-Dennis, Josh Hare and Sam Matthews are all long-term absentees.
