Port Vale are preparing to play their first meaningful game since playing out an entertaining 3-3 draw with Charlton on January 6.
The Valiants saw their away clash with Reading abandoned due to fan protests, before last Saturday's home meeting with Wycombe Wanderers was postponed because of a frozen pitch.
Although they have at least two games in hand on the teams around them, Port Vale are currently battling for their League One survival with just four points separating them from the relegation zone.
While they are bracing themselves for a tough test, Andy Crosby's side can take confidence from the fact that they have lost just one of their last four home league games (W2, D1).
Having scored two goals in each of those four home matches, Port Vale will hope that they have the firepower required to trouble a Portsmouth side that boast the joint-best defensive record in the division.
Portsmouth, meanwhile, bounced back from consecutive defeats to claim a narrow away win over Fleetwood Town last weekend.
Abu Kamara's 25th-minute strike proved enough to condemn the relegation-threatened side to a 1-0 defeat and end Pompey's three-game winless away run.
While Portsmouth remain top of the table, they are only two points clear of third-placed Bolton Wanderers, who have two games in hand over the league leaders.
Pompey will fancy their chances of adding to their points tally on Saturday, having lost just two of their 14 away league games this season.
They can also take confidence from the fact that they have won two of their last three meetings with Port Vale (D1), including a 2-0 win in October's reverse fixture.

Port Vale possible starting lineup:
Ripley; Smith, Lowe, Iacovitti; Massey, Gore, Weir, Grant; Wilson, Chislett, Ikpeazu

We say: Port Vale 1-2 Portsmouth
After Portsmouth got their promotion bid back on track last weekend, we think that they will record a second straight victory this weekend, especially as they have won two of their last three matches against Port Vale.
