Scottish Championship bottom side Partick Thistle "will not accept" being relegated to League One after the SPFL proposed to end the term as it stands.
The 42 SPFL clubs have until 17:00 BST on Friday to vote, and should 75% of teams in each divisions support it Thistle would be demoted to League One.
The Firhill club were two points behind Queen of the South having played a game fewer when the season was halted.
Thistle say they are "engaging with others to amend the proposal".
- Clubs to vote on ending lower-league season
- Rangers call for money, not rule changes
- Hearts will not vote for SPFL plan

A club statement added: "We believe that the proposal requires significantly more discussion, scrutiny and debate before any vote can be taken.
"We believe it doesn't meet the basic principle that no club should be left worse off by this important decision.
"It also seems to link acceptance of the proposal before payments can be made to hard-pressed clubs but, in our opinion, the two things do not need to be linked.
"Money to clubs is a priority, the proposal could be debated in slower time."
Thistle had nine games left to try to salvage their second-tier status, but face having it taken out of their hands.
Should nine Premiership clubs, eight in the Championship, and 15 in Leagues One and Two combined support the proposal, the Glasgow side's relegation would be confirmed.
However, the SPFL says that, should the plans be approved, it would commit to consulting with clubs in April and May about reconfiguring the leagues for the 2020-21 campaign.
Queen of the South will discuss the proposals as a board before voting but acknowledge there will be "winners and losers".
Chairman Billy Hewitson added: "I think we have reached the stage where the majority of clubs will want the season finished so they can get the balance of the money they are owed."
It would be the second time in recent years that Thistle had been demoted as a result of rules changing.
In 2004, the Firhill side finished bottom of the top flight but seemed likely to avoid relegation on account of second-tier champions Inverness Caledonian Thistle not meeting stadium criteria.
However, after two round of votes, it was decided to let the Highland side groundshare with Aberdeen and take their place in the top league.
