The Hawks may look to new addition Jonté Smith to provide the cutting edge as they host Hayes & Yeading at Westleigh Park (3pm).
Manager Lee Bradbury is without two key attackers – winger Christian Nanetti and striker Dennis Oli.
The duo limped out of the midweek clash with Farnborough which Hawks won 2-1 on Wednesday.
They could be facing weeks on the sidelines.
Bradbury brought in Bermuda striker Smith, on loan from Crawley, earlier this week.
The Hawks boss has also recruited Pompey’s Ashley Harris on a month-long loan deal to improve his options further.
Smith was originally signed up to supplement the talents of the attacking trio Oli, Nanetti and Sahr Kabba.
But he could now be the man to step in and fill the void with injuries hitting hard at Westleigh Park this season.
‘They are two big losses for us,’ said Bradbury.
‘Christian has been fantastic and Dennis will be a big player for us once fully fit.
‘Losing both of them blunts our strike-force a bit.
‘We have been missing a fox in the box – someone who can show a bit of composure in front of goal.
‘Sahr Kabba is our only striker to score so far this season with two goals.
‘Jonté scored lots of goals on loan at Met Police, albeit at a lower level, but now maybe he can help us take more of our chances.’
Bradbury will hope the additions of Harris and Smith can help his team build on their impressive midweek victory.
The Hawks were pleased to get back to winning ways with the 2-1 win over Farnborough.
Goals from Nic Ciardini and Ryan Woodford proved enough to halt the run of two defeats with a welcome three points.
But it wasn’t a completely polished display from the Hawks as they struggled at times.
They suffered a poor 45 minutes and then conceded a disappointing goal late on in the contest.
‘We have been sloppy at times with too many passes going astray,’ said Bradbury.
‘It took us a while to get to grips with the wet surface.
‘Once we did, in the second half, we were the better side and ran out deserved winners.
‘You can’t play for 45 minutes, though, and expect to be contenders and we are looking at our consistency levels.’
Experienced defender Pedro Monteiro is also an injury doubt.
Entry at Westleigh Park this season is £5 for Pompey season-ticket holders and £1 for accompanying children.
Hawks: Fitzsimons, Strugnell, Woodford, Harris, Blanchett, Ryan, Kewley-Graham,Ciardini, Hutchinson, Monteiro, Kabba, Smith, Jones, Ramsey, Newton, Przespolewski, Searle.
