Rennes manager Frederic Antonetti has intimated that Yann M'Vila and Chris Mavinga may not play for the club again this season following their behaviour while on international duty with France Under-21s.
M'Vila and Mavinga, along with Antoine Griezmann, Mbaye Niang and Wissam Ben Yedder, went nightclubbing in Paris before the second leg of France's Under-21 2013 European Championship qualifier against Norway.
The pair have since been condemned to training with Rennes' reserves, while they have not been named in Friday's squad for the Ligue 1 trip to Saint-Etienne.
"We can talk about betrayal," Antonetti said. "I talked so much with them, but it was useless. I'm the first to suffer in this situation.
"I don't know yet when they will return, but it couldn't be until May 31. I won't have confidence in them as men anymore and I can't make the difference between the man and the player. That's why I'm affected - more than I show.
"I made this decision to make them understand, but I don't know if they do. I have doubts about that. I made this decision for the club too, they have to be professional. They'll come back one day."
The French Football Federation has opened disciplinary proceedings against the five players, while France coach Didier Deschamps and UEFA president Michel Platini were critical of their actions.
