Thomas dropped by France
France coach Philippe Saint-Andre has dropped rising star Teddy Thomas for Saturday's Test against Argentina after he missed a training session.
The 21-year-old Racing Metro wing, who has scored four tries in his first two appearances, has been replaced in the squad by Maxime Medard after he failed to attend training on Wednesday evening.
"In the France group there are rules that everyone should respect," Saint-Andre told L'Equipe.
"Teddy, who we love a lot, has forgotten these. When you play in the France team you have to be beyond reproach and respectful on and off the field.
"I had a meeting yesterday (Wednesday) with Teddy and he understands. I'm sure it will make him grow up."
Vice-president of the French rugby federation Serge Blanco added: "The message is clear: There are rules of life in the France team that must be respected."
Thomas apologised for his actions his official Facebook page.
He said: "The rules of the France group shouldn't be broken and I want to offer my sincerest apologies to the staff and the France team, to my team-mates, to all the Bleus fans and our sport.
"I also want to clarify, not by way of justification, that it was my fault and although it should be punished, it was in no way a question of insolent or arrogant behaviour.
"My support of the team for the game this weekend is total and unwavering."
The other changes to France's starting line-up sees Maxime Mermoz replace the injured Alexandre Dumoulin while Sebastien Vahaamahina comes in for Yoann Maestri in the second row. Xavier Chiocci makes his first start at loosehead while Benjamin Kayser has been named as starting hooker.
Argentina are set to welcome back captain Agustin Creevy from injury in one of four changes to their starting XV at the Stade de France.
Nicolas Sanchez is named at fly-half, Juan Martin Hernandez moves to inside centre and Marcelo Bosch starts at outside centre while Juan Imhoff returns to the right wing.
France have won their autumn internationals against Fiji (40-15) and Australia (29-26) while Argentina were beaten 41-31 by Scotland before claiming a narrow 20-18 victory against Italy.
