Longford Town manager Daire Doyle says it's a "fiasco" that his club are unsure who they will play in 16 days' time when the season commences.
And he says it's still a possibility that his club won't fulfil their proposed fixture at home to Shamrock Rovers II as opposition still exists within the First Division to the Dublin club's presence in the league.
"It's something we as a club have to be prepared to do," says Doyle.
Rovers have maintained their stance that their second string are now members of the league and will play in Longford on February 22.
Meanwhile, the entire season is facing potential chaos, depending on the outcome of the FAI's club licensing system today, with the possibility that some clubs - aside from troubled Limerick FC - could be denied a licence to play in 2020, with six clubs reported to be in peril. A revised fixture list was issued last month for the new First Division season, containing 11 clubs.
While all 10 Premier Division clubs were represented at a media day near FAI HQ in Abbotstown yesterday, there was no official presence from Limerick FC or Athlone Town. Shamrock Rovers II had a manager and a player present.
But the start of the First Division campaign is shrouded in doubt, with Limerick FC still included in the revised fixture list - even though they don't have a team.
And the uncertainty is a cause of anger to Longford boss Doyle, whose club are due to play at home to Rovers II on the first weekend of the season.
"It's a farce and shambles, club licensing is finished on Thursday and we'll only know then who exactly is in the league," said Doyle.
"Two fixture lists have come out, the second list is an embarrassment, they showed a total lack of respect for the league, they lacked any information or clarity on how it would work.
"It's stunning that I am talking two weeks out from the start of the league and we don't know who we're playing. It's a bit of a fiasco," added Doyle.
