Kilmarnock chief Michael Johnston reckons commercial concerns will prevail over principles of sporting integrity when SPL clubs meet on Monday.
The SPL clubs will meet on Monday to vote on financial fair play proposals.
New rules would see greater penalties for clubs in administration and sanctions on clubs who undergo an "insolvency transfer", which would see them docked 10 points for two seasons and 75 per cent of their SPL income for three years.
Earlier this week, the vote was adjourned for seven days and American Bill Miller subsequently assumed preferred bidder status from Rangers administrators Duff and Phelps.
Miller plans to create a new company and buy the club's assets while Duff and Phelps aim to take the current club out of administration via a Company Voluntary Arrangement.
He will have to apply to the SPL board to acquire Rangers' share in the competition, with any potential sanctions currently at that body's discretion.
Kilmarnock chairman Johnston, who is not on the board but will vote at Monday's general meeting, told BBC Scotland: "We need more clarity on Bill Miller's plan for Rangers and how it will it structured.
"There is a feeling that member clubs see the commercial benefits of having Rangers in SPL, even if it is a newco.
"Member clubs are mindful of a sporting integrity aspect but the commercial benefits outweigh that."
