The proposed merger between Racing 92 and Stade Francais will be discussed at an emergency meeting of France's Ligue Nationale de Rugby (LNR) on Friday.
The two capital-based outfits stunned the rugby world on Monday when they announced they would pool their resources from next term and form a Top 14 Paris super club.
But the move has been frowned upon in some quarters with France's Stade centre Jonathan Danty revealing that the news had sent shock waves through the Les Bleus camp, and claims the players had voted to strike.
The LNR has responded by convening an emergency meeting with Racing 92 and Stade officials, as well as the representatives of players and coaches from both clubs, to discuss the plan.
An LNR statement said: "The project to bring together the professional sections of the Stade Francais Paris and Racing 92 is provoking numerous reactions, questions and concerns, both on the social and cultural impacts linked to this rapprochement and on the sporting consequences on the Top 14.
"After reviewing this exceptional situation by the steering committee, the LNR proposes to convene an emergency meeting on Friday with representatives of the two sports companies and the two associations, and representatives of players and coaches to evaluate and ensure the best treatment of this project.
"The LNR calls for dialogue and will pay close attention to this unprecedented dossier in the world of professional rugby and intends to ensure the interests of all stakeholders, in particular players, coaches and co-workers of both clubs."
