Pompey will search for back-to-back victories for the first time in more than a month when they travel to Wycombe on Saturday.
Paul Cook’s side know they need to follow up the midweek rout of York with another good result in order to maintain pressure on the top three.
But they are facing a Chairboys side who sit just two places and one points outside the play-off spots.
Like the Blues, it is their away form that is more impressive, with wins on the road compared to just three at Adams Park.
Wycombe will be playing on home turf after a run of four successive away games that has seen them drop only two points and progress in the FA Cup.
They finished fourth in League Two last term, but lost on penalties to Wycombe in the play-off final at Wembley.
Wanderers also failed to beat Pompey, with both of the league clashes finishing all square.
TEAM NEWS
Paul Jones (knee), Gary Roberts (ankle) and Matt Tubbs (ankle) are all sidelined, while Jayden Stockley and Jack Whatmough are not yet ready for first team action.
The hosts could hand debuts to midfielders James Ferry and Jermaine Udumaga, who have arrived on loan from Brentford, but former Blues loanee Marcus Bean is out with a knee injury.
