Troyes said the abuse was picked up over the microphones of the Amazon Prime broadcast of the match, which was played behind closed doors and ended 1-0 against Marseille.
A press release states: “These comments are simply unacceptable and taint a sport, football, which is essentially multicolored and multicultural.
“The club strongly condemns all forms of racism or xenophobia.
“ESTAC supports all the steps taken to fight against this scourge. The club will accompany the player in any action he wishes to undertake.
Ligue 1 has confirmed that the LFP, the governing body of French football, will investigate the case. Marseille did not immediately respond to CNN’s request for comment.
The match was played without supporters as a punishment for crowd problems during Marseille’s clash with Paris Saint-Germain in October. The result leaves Marseille fourth in Ligue 1, while Troyes is 17th after three consecutive defeats in the league.
Suk, who joined Troyes from Reims last year, has scored 10 goals in 68 French league appearances.
