Manager Ally McCoist insists league reconstruction plans would be a “slap in the face” for Rangers and their supporters if put in place for next season.
The Scottish Premier League and the Scottish Football League have agreed in principle to a restructuring plan that would see the organisations merge in a 12-12-18 structure.
A vote on the proposals is likely to take place later this month and, if approved, could come into effect as early as next season.
That would mean Rangers remaining in the bottom tier of Scottish football for a second consecutive season, even if they win the Irn-Bru Third Division title.
The potential time frame for a return to the top flight would remain the same, but McCoist is furious with plans to “move the goal posts”.
He said: “I don’t think the league reconstruction can go through. There is a complete lack of sporting integrity.
“I think the vast majority of the footballing public - the fans included - are probably in agreement that we need change, but you can’t have change during a season.
“You can’t move goal posts and effectively waste people’s seasons.
“If it goes ahead and starts next season, this season is meaningless for a lot of teams.
“There would be no point. What a slap in the face that would be to everybody in SFL3, including our fans and players.”
