Investigation opened into Ligue 2 clashes
It is the second case of violence in the French second division in a month after Venezuela defender Gabriel Cichero of RC Lens was banned for 10 months, five of them suspended, for kicking a Bastia official last month.
"Following the unacceptable incidents that happened after the Metz v Amiens game, the French professional league president Frederic Thiriez... has asked for an investigation to be conducted as soon as possible," the LFP said in a statement.
The incidents started after an Amiens player hit an opponent, triggering a brawl.
"It is a pity to finish [the game on such a sad note," Metz captain Kalidou Koulibaly told French sports daily L'Equipe on Saturday.
