Last time out, Danny Cowley’s men secured a well-earned point at play-off rivals Ipswich to remain in the play-off hunt.
And a win at the sixth-placed Pilgrims could see Pompey reduce the deficit to the top six to four points – keeping them in with a chance of securing promotion.
Cowley made two changes for the trip to Ipswich on Saturday but could make just the one tonight as he continues to rotate his central midfielders.
Here’s how we predict Pompey will line up tonight.
1. GK: Gavin Bazunu
Despite an uncharacteristic mistake against Crewe seven days ago, the Manchester City loanee kept his 15th clean sheet on Saturday against Ipswich and will continue his place between the sticks. Photo: The News
2. RCB: Hayden Carter

3. CB: Sean Raggett
Hasn't scored in his last two games and is due a goal. Almost put Pompey ahead in the second half against Ipswich and has been a regular feature in the Blues' back-line this season. Photo: The News
4. LCB: Clark Robertson
With Connor Ogilvie filling in at left-wing back over recent games, Robertson has been forming a solid partnership with Raggett and Carter. His injury woes seem to be behind him and he's impressed with his consistency since his return. Photo: The News
