The FAI has written to League of Ireland clubs outlining the finer details of a return to action - and confirmed they will relegate teams who do not come back to finish a truncated campaign.
The FAI and the Premier and First Division clubs had agreed on an 18-game season to kick off again on 31 July.
However, some Premier Division clubs are unhappy with the prospect of a much shorter campaign deciding relegation.
On Thursday night, the FAI emailed clubs detailing the financial arrangements to support a restart following the Government commitment of €40m to the FAI, the GAA and the IRFU.
A UEFA Solidarity payment, estimated to be €700,000 , will also be split equally between all 19 clubs in the Premier and First Divisions, while each of the quarter-finalists in the FAI Cup will receive an additional payment of €25,000.
However, the clubs were told that a failure to return will result in a complete deduction of a team's points total and relegation at the end of the season.
The email, which has been seen by RTÉ Sport, says: "Any club deciding not to finish the 2020 season will have their points zeroised and will be relegated at the end of the season in line with provisions of the Participation Agreement."
On Friday, PFAI general secretary Stephen McGuinness addressed the suggestions that any club that can't return to action will be relegated.
He said there is intense work going on behind the scenes to ensure that "worst case" does not happen.
"If there is a situation where the club financially just cannot return, there’s not much we can do," McGuinness told RTÉ Sport's Tony O'Donoghue.
"We're going to work with everybody to ensure that that doesn't happen. But if a club takes that decision and feels that financially they can’t run, then we have to accept that.
"The player's contract will still be there so there's a lot of work to be done on that with ourselves and Stuart Gilhooly our lawyer to try and resolve the financial side of things, but in the main I think the majority of clubs realise that it's important to come back and play."
