St Mirren chairman Stewart Gilmour admits even his own board are split on league reconstruction plans as he stressed the Paisley club still needed more details before formally voting for the current proposal.
Saints and Motherwell have both arranged a meeting of supporters in the coming days to explain plans for a merged 12-12-18 Scottish league structure.
Scottish Premier League chief executive Neil Doncaster revealed on Monday after a meeting that the 12 top-flight clubs had given their "unanimous backing" to move forward with the plans, which will be debated by Scottish Football League clubs on Thursday.
But nothing has been decided yet and the St Mirren board will present their feelings to fans and listen to views at a meeting at St Mirren Park at 7pm on Thursday.
In a statement, Gilmour said: "I would wish to clarify that contrary to some media reports, no formal vote was taken although the clubs have agreed unanimously to take this proposal forward to the SFL for further talks and discussion.
"We as a club and many other clubs will not vote until we know exactly what is on the table in front of us, this will not be clear until discussion between the SFL clubs takes place and they take their view on this proposal.
"One thing is certain, we will never all agree on a system for 42 clubs, nor are any of us certain that our own thoughts are the correct ones, even the board of your club have differing thoughts, it is an impossible situation for us all to agree.
"However, it is important we discuss the options available to us which include the current one, which is under heavy criticism."
Motherwell directors will meet on Saturday afternoon with members of the Well Society, the fans' group with a stake in the club.
