While Swansea sit four points adrift of Welsh rivals Cardiff City, Millwall have recorded a point fewer after failing to win either of their two games since the resumption.
Having put together a three-match unbeaten streak before the coronavirus pandemic, Millwall boss Gary Rowett would have been confident of prolonging that run upon the resumption.
However, despite showing glimmers of their qualities at both ends of the pitch, just one point has been recorded from fixtures against Derby County and Millwall respectively.
After seemingly being on the brink of moving into a playoff spot, Millwall now face an uphill task just to remain in contention, reaching a point where a defeat at this stage could realistically leave them out of the picture.
Nevertheless, Rowett will view a home encounter against opponents just above them and the following three games coming versus teams looking to avoid relegation as a window of opportunity.
Millwall have no-one left to play who currently occupy a position in the top eight, arguably providing them with the best run-in of any clubs looking to earn promotion to the Premier League.
Like the London outfit, Swansea missed out on a chance to gain maximum points against a side sitting in the bottom three at the weekend, suffering defeat at home to then-bottom-placed Luton Town.
Since netting three times in the first half at Middlesbrough last weekend, Swansea have gone three halves of football without finding the back of the net, a record which will naturally concern Steve Cooper.
The Welsh club now possess the second-worst scoring record, coincidentally behind Millwall, of the teams in the first 13 places, and the pressure is on their forward players to improve that return.
On a positive note, Liverpool loanee Rhian Brewster has produced his best performances away from the Liberty Stadium, netting all but one of his half-a-dozen goals on the road.

Swansea City Championship form: WLDDWL
Swansea boss Cooper will be without Jordan Garrick, who picked up a red card after being introduced as a substitute against Luton.
Barring any fitness issues or tiredness within the ranks, Cooper could retain the same starting lineup.
Millwall possible starting lineup:
Bialkowski; Romeo, Hutchinson, Cooper, M.Wallace; Williams, Woods; J.Wallace, Molumby, Ferguson; Smith
Swansea City possible starting lineup:
Woodman; Roberts, Guehi, Wilmot, Bidwell; Byers, Grimes; Kalulu, Gallagher, Ayew; Brewster
We say: Millwall 1-1 Swansea City
Given what is at stake, both clubs can ill-afford a defeat on Tuesday evening. With that in mind, we are expecting a tense, low-scoring draw to be played in East London.
