Bayonne scrum-half Mike Phillips and wing Cedric Heymans have been suspended indefinitely by the Top 14 club according to reports in France.
Phillips, who is Wales' first choice number nine, was fined and suspended while Heymans, who has played on the wing and at full-back for France, received only a suspension until further notice for what Bayonne president Alain Afflelou described as "unacceptable off-field behaviour".
"I'm furious - outraged," he told L'Equipe.
"This is unacceptable and not worthy of a professional player.
"It shows a lack of respect for the club's partners and the public.
"He will not play again until further notice and we will also punish him financially."
Afflelou revealed that Phillips, who is out if action due to a hand injury at the moment, has been in trouble for similar behaviour before.
"This is not the first time he's been sick," he said.
"I'll talk to the players tomorrow to tell them that from now on, we'll only give opportunities to those who want to fight with commitment and respect for the team, our commercial partners and the public.
"Others, regardless of who they are - if they carry on behaving like spoiled children, they will no longer wear the shirt of this club."
Bayonne are currently one place off the bottom of the Top 14 table and it is believed that Phillips and Heymans were punished after they were partying after last week's 35-6 defeat to Toulouse.
