The Nice midfielder has been banned for the final 11 games of the season after seriously injuring Jeremy Clement in his side's 4-0 demolition at the hands of Saint Etienne.
The midfielder's sentence means he will miss the rest of the season after his tackle on Jeremy Clement resulted in a broken leg and several shattered ankle ligaments.
The horriffic lunge on Clement, who is expected to be out for around six months, took place 24 minutes into the Ligue 1 tie with the score at 1-0. The Monaco loan signing will not be appealing the decision.
"I have nothing to say about the penalty, it is their decision." the 20-year old Eysseric told L'Equipe as he left the hearing. "I explained my feelings and the action, they all listened."
Les Aiglons' defeat meant they were overtaken by St. Etienne in the Ligue 1 table as they dropped to fifth place, two points behind Les Verts in fourth.
