Danny Hylton is unlikely to return for the visit of the Daggers as the Shots look to keep their survival hopes alive.
The 12-goal striker was back in training a couple of weeks ago having been missing since the start of March with a knee problem but the injury has not responded as had been hoped and a couple of minor setbacks have delayed his return to match action.
Shots boss Andy Scott still hopes Hylton may have a part to play over the last two games of the campaign but a comeback is looking increasingly doubtful.
Midfielder Adam Mekki made his return from a groin injury as a second-half substitute in Tuesday night's disappointing 2-0 home defeat to Southend, while fit-again defender Troy Brown made his first start since February after a knee injury.
Scott is not expected to have any new injury or suspension problems but remains without long-term absentee Aaron Morris (cruciate ligament damage).
The Shots, bottom of League Two and four points from safety, realistically must win both of their final two games of the season to have a chance of avoiding relegation out of the Football League.
Goalkeeper Chris Lewington faces another fitness test ahead of Dagenham's trip to the Shots.
Lewington failed to prove he had fully recovered from his back injury ahead of last weekend's 1-0 home defeat to Oxford, duly forcing him to miss a fourth match in succession.
And he will again be assessed prior to the encounter at the EBB Stadium, with Jordan Seabright expected to retain his place between the posts if Lewington fails to make it.
Interim boss Wayne Burnett, who has no new injury or suspension problems, remains without strikers Sam Williams (knee) and Josh Scott, who has picked up a neck problem having recovered from his hip complaint.
The Daggers, boasting just one win in seven, sit just three points above the drop zone with two matches remaining, although their fate is in their own hands as they come up against bottom-of-the-table Aldershot before a final-day clash at home to 21st-placed York.
