Featherstone chief executive Craig Poskitt says the dual-registration system is "bad for the integrity of the sport".
Rovers, minor premiers in the Championship for the past three seasons, have refused to adopt the system and a partner club, as have rivals Leigh, Sheffield and Halifax.
It has led to much criticism, but Leeds coach Brian McDermott said last week that he believed dual-registration is raising standards outside Super League and is good for the game.
Poskitt told the Yorkshire Evening Post: "It is not working.
"I think from Super League clubs’ point of view they will be quite happy saving six-figures per annum with no Under-20s.
"But it has been bad for the progression of the game and certainly for the integrity of the lower clubs, it is abysmal."
This epic clash will be the last time that Rhinos' rugged veterans Jamie Peacock, Kylie Leuluai and Kevin Sinfield will wear the Leeds colours, and they will be keen to end their playing careers on a high.
