Scottish Premier League chief executive Neil Doncaster urged clubs to vote for his now-completed draft plan for reforming the game - but then admitted a decision might not come this month as planned.
A vote had been pencilled in for the scheduled meeting on April 18, with 11 out of 12 clubs needing to back the overall package for it to be implemented, but Doncaster - whose ultimate aim is a merger with the Scottish Football League and introduction of a pyramid structure - cast serious doubt on whether agreement was imminent.
Doncaster told ESPN: "We are going to the meeting on April 18 with the clubs, they have a plan in front of them and it's up to them where we go from here. If they wish to put forward alternative ideas and suggestions, that's the time to do it."
He added: "I think there is a real need and desire for change and hopefully we will see that reflected in views that come out of the April 18 meeting.
"They can still make a decision on the day if they wish, ultimately it's down to them.
"I don't get a vote and neither does the chairman (Ralph Topping), so it's down to 12 clubs who have to decide what they want for the future of Scottish football."
The former Norwich City chief executive summarised the 100-page document on a blog on the SPL's official website.
A Premier League of 10 teams would receive 80% of the money raised, with 15% going to a Championship and 5% going to League One and League Two teams.
Doncaster claimed that would see £3.7million shared among the lower-league clubs, more than double the present cash, with the team winning the second tier receiving £500,000 - more than six times their current prize money.
The SPL promised a more even share within the top flight, "redistributing money away from the top two positions in the league and reallocating it to the other eight clubs".
