Lyon have sent defender Marcelo to train with the reserve team with immediate effect, in the aftermath of a dressing room incident following a recent shock 3-0 defeat to Angers.
On Tuesday the French giants released an official statement in which it was clarified that 'the inappropriate behavior of Marcelo in the locker room after the match in Angers justifies this decision, which was taken unanimously by Olympique Lyonnais' management team.'
The Brazilian is said to have acted in an inappropriate manner towards a team-mate, as tensions were high following the loss.
In the match Marcelo had been left fuming and red-faced after attempting a pass-back to goalkeeper Anthony Lopes, only for a drastic miscommunication error to occur.
Marcelo watched on as the ball slid past his goalkeeper and tucked into the bottom corner, as Angers players and fans began to celebrate all around him.
The match ended in defeat and Lyon continued their poor start to the season, with two losses from two.
Lyon's full statement read: 'The inappropriate behavior of Marcelo in the locker room after the match in Angers justifies this decision, which was taken unanimously by Olympique Lyonnais' management team.
'The player was briefed on this decision yesterday afternoon by Juninho and Peter Bosz.
'Olympique Lyonnais' management reiterates that all of its players must demonstrate an unwavering mindset and a commitment to quickly return to recording results in line with the club's ambitions.'
Marcelo, now 34, was handed a one-year contract extension earlier in the year following a sustained period of form in a Lyon side which finished the previous campaign strongly.
Now, however, it is reported that the club will soon be cutting ties with him as a result of his action.
Tellingly, at the end of their official statement Lyon added that further transfer targets were being eyed up before the window closes in two-weeks time.
The statement added: 'Olympique Lyonnais would also like to point out that its management team is actively working on several specific recruitment targets, in close consultation with coach Peter Bosz and wants to implement a relevant and coherent transfer strategy, without giving into media pressure, in order to take the best opportunities while also considering the current market and the resources available to the club to make good on its ambitions.'
