It’s a full League Two fixture list tonight as the season hits the home straight.
Pompey have the opportunity to cement their place in third spot, yet will also be casting glances at the outcomes of their rivals.
The clash between Carlisle and Luton represents the most intriguing encounter as fifth are pitched against sixth.
Luton’s defeat to Stevenage at the weekend has delivered a jolt, yet they remain the only club in the top 11 with a game in hand.
Despite presently five points adrift of the Blues, that spare match offers them a little hope.
In the meantime, Nathan Jones’ side travel to Brunton Park to face a plummeting Carlisle.
The hosts are reeling from four successive defeats and have won only five times since December 3, thereby relinquishing their place in the top three.
Keith Curle’s wilting team are also four points behind Pompey, so continue to remain a threat.
League Two’s in-form team are Stevenage, with four successive wins and eight victories from their past nine fixtures.
That outstanding run has lifted them into fourth, to stand four points behind the automatic promotion spots.
They are also Pompey’s opposition this weekend, when Darren Sarl’s men serve as the hosts.
Before then, Stevenage travel to Blackpool, who themselves hover on the fringes of the play-off spots.
The Tangerines have not won a match since falling to a Fratton Park defeat on Valentine’s night, a spell of six winless games.
They have, however, lost only once at Bloomfield Road in 2017 – a factor which could play in their favour.
Although, they will need to silence a Stevenage side who also boast the Sky Bet manager of the month for February.
Elsewhere, Plymouth make the trip to a Wycombe side who still retain hope of reaching the play-offs.
Since defeating Pompey at the start of February, Gareth Ainsworth’s side have won only once in nine matches in all competitions.
That dismal run has seen them drop to 11th – albeit still just three points adrift of the play-off spots.
Plymouth, with four wins from their last 10 matches, sit six points above the Blues.
Finally, League Two leaders Doncaster tonight host Notts County.
Darren Ferguson’s men are four points clear at the top – and 10 ahead of Pompey.
