Allott has missed the York City, Curzon Ashton and Blyth Spartans fixtures due to a thigh strain but Elliott is hopeful, once again, that his 10-goal striker will be back to face the Quakers (kick-off 3.00pm).
Fellow striker Andre Johnson missed out against Blyth due to illness and could potentially return to the squad this weekend.
Bradford City loanees Tom Clare and Cameron Hawkes will be hoping for further opportunities, with the former having made four substitute appearances to date while the latter is still awaiting his United bow.
Darlington, who overcame the nine-man Pilgrims 1-0 in the reverse fixture in October, are 10 points clear of the relegation zone with four matches to play.
They have picked up four wins and eight draws on their travels so far this season.
Last season's corresponding fixture ended 1-1 way back in September 2017.
Saturday's match referee is James Bell, who has presided over United's victories against Guiseley (home) and Kidderminster Harriers (away) so far this season.
