UEFA have confirmed Marseille fullback Patrice Evra is facing a lengthy ban after attacking a fan last night.
Evra was sent off and on Friday UEFA announced the 36-year-old would miss "at least one match", with the organisation's disciplinary body set to discuss his case at its next meeting on November 10.
Marseille have begun an investigation into the incident.
"A professional player must maintain self-control despite provocations and insults, no matter how unjustified they may be," the Ligue 1 club said in a statement.
"At the same time, the club can only condemn any destructive behaviour by pseudo-supporters which hurts their own players at a time when they should instead be supporting their team."
Further to UEFA investigation's into Evra, the governing body has charged Marseille with breaches of Article 16 of its disciplinary regulations: namely the "field invasion by supporters, the setting-off of fireworks and acts of damages."
