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.
