The Hawks include new loan recruit Ellis Martin in their squad as they host relegation-battling Boreham Wood at West Leigh Park (3pm).
Martin has arrived from Pompey for a month to bolster manager Shaun Gale's restricted resources.
'We don't have too many natural left-footed players in the side and Ellis is a six-footer, which should give us more of a physical presence,' said Gale.
'I had him with me as a kid when I was at Pompey and he will add to our strength in depth.
'He is a good athlete, technically very good on the ball, and will be a welcome addition.
'The lad will also give me extra options because he can play at left-back and wide on the left.
'Pompey boss Steve Cotterill has been very helpful and it helps both parties out.'
The Hawks will be delighted to finally stage a home game after the recent weather and a collapsed drain underneath the pitch meant that several games had to be postponed.
The home side are confident, however, that the combination of a few dry days and some urgent repair work to the drainage system will mean the game will go ahead.
It's a fixture the Hawks need to win if they are to make up lost ground on the division's leaders.
Gale is adamant the Hawks are still capable of launching an assault on the end-of-season play-offs.
'It is important that we pick up three points, particularly at home,' said Gale.
'We have been playing well but need to turn the recent draws and defeats into wins.
'The bitty nature of the last month or so hasn't helped and has prevented us picking up any momentum.
'It is important that we maintain our belief because a couple of back-to-back wins can make all the difference.
'We have a hectic period ahead – 24 games in 13 weeks – but have to make that work for us.
'There is no way our season is over and there is still plenty to play for.'
Ian Selley came through his return from a calf injury at Weston-super-Mare last weekend without any reaction and is expected to play a part against Boreham Wood.
Fellow midfielders Sammy Igoe and Craig Robson, however, are still ruled out by injuries.
Meanwhile, Leon Cashman is absent because of his sea duties with the Royal Navy.
Hawks: Howe, Newton, McDonald, Hinshelwood, Martin, Selley, Pearce, Simpemba, Fogden, Hopkinson, Williams, Tiryaki, Sole, Edwards, Ramsey, Sewell, Ashmore.
