Pompey are looking to avoid racking up successive league defeats for the first time this season when they travel to Blackburn on Saturday.
Kenny Jackett’s side go into the game on the back of 2-1 midweek defeat at Doncaster, which saw two own-goals and a red card.
Their opponents had only slightly better fortunes, as they were held to a draw by bottom-of-the-table Plymouth on home soil.
It leaves the sides separated by single position in the League One standings, with 10th-placed Blackburn above the Blues on goal difference.
But Rovers have played two games fewer than most sides in the division, as international call-ups have resulted in postponements.
They have won half of their six home league fixtures, seeing off MK Dons (4-1), Rotherham (2-0) and Gillingham (1-0).
Tony Mowbray’s men have collected just a single point from the most recent two, however, with that Plymouth stalemate preceded by a defeat to Bury.
You have to go all the way back to 2010 for the last meeting between the teams, with a goalless Premier League encounter made famous by reporter Chris Kamara missing Anthony Vanden Borre’s sending off.
Top scorer Brett Pitman could return for Pompey after recovering from a knee injury, while Dion Donohue is available, having successfully appealed his red card at Doncaster.
But the Blues are still missing Curtis Main (hamstring), Adam May (ankle), Damien McCrory (knee) and Jack Whatmough (knee).
Rovers will be without Darragh Lenihan (metatarsal), while a late decision will be made about the fitness of Paul Downing (hamstring) and Corry Evans (ankle).
