The hosts extended their losing run on Saturday afternoon with a defeat against Barnet, while Oldham earned a point at home against playoff-chasing Solihull Moors.
Match preview
Wealdstone's worrying period of results continued on the weekend as they lost 2-0 at home to Barnet, extending their losing run to three matches in the National League.
Second-half goals from Nicke Kabamba and Harry Pritchard ensured the points were awarded to the Bees at the full-time whistle - the Stones have now failed to register a goal in back-to-back home matches.
A three-game winning streak at the beginning of March raised expectations among the Wealdstone faithful that a playoff charge may have been on the cards, but their side are currently down in 11th in the standings, seven points behind seventh-placed Boreham Wood.
Stuart Maynard has guided the Stones to successive bottom-half finishes in the National League since taking the charge in early 2021 - he will be aiming to land the club their first-ever top-half spot in the fifth tier.
Oldham are now three games without a win after a 1-1 draw at Boundary Park against Solihull Moors on Saturday afternoon, with the visitors bagging a 94th-minute equaliser through Jack Stevens.
The Latics faithful were left feeling deflated after the cruel manner in which two points were snatched away from them, but their side have an immediate opportunity to put things right on Tuesday night in Middlesex.
David Unsworth's men are one of the few sides in the National League who can safely assume they will be playing fifth-tier football next season, with the club currently nine points ahead of 21st-placed Gateshead with just eight games left to play.
Oldham have struggled massively on their travels this campaign having earned maximums in just three of their 19 fixtures away from their Boundary Park home - only four other sides have won fewer on the road.

Team News
Wealdstone boss Maynard was pleased with his side's performance despite the Derby Day defeat against Barnet on Saturday, although the likes of Tarryn Allarakhia and Dominic Hutchinson will be pushing for starts.
Sam Howes returned in between the sticks on Saturday for the Stones after he went off for England C duty earlier in the week - the keeper is expected to retain his place in net on Tuesday night.
Oldham have a host of injury concerns ahead of this midweek clash, with Alex Reid set for a race to be fit by the end of the campaign due to a hamstring strain.
Both Chris Porter and Hallam Hope remain sidelined as long-term absentees for the Latics - boss Unsworth has very limited options at the top end of the pitch.
Wealdstone possible starting lineup:
Howes; Clayden, Barker, Cook, Taylor; Habergham, Simper, Ferguson, Andrews; Obiero, Olomola
Oldham Athletic possible starting lineup:
Hudson; Green, Yarney, Hogan, Kitching; Sheron, Sutton, Rooney, Shelton; Sambou, Nuttall
We say: Wealdstone 1-0 Oldham Athletic
