Troyes said the abuse was picked up by the microphones of the Amazon Prime broadcast of the match, which was played behind closed doors and finished 1-0 to Marseille.
A statement said: “These remarks are simply unacceptable and come to mar a sport, football, which is essentially multicolored and multicultural.
“The club strongly condemns all forms of racism or xenophobia.
“ESTAC supports all steps taken to fight against this scourge. The club will support the player in any action he wishes to take.”
Ligue 1 confirmed that the LFP, French football’s governing body, will investigate the case. Marseille did not immediately respond to CNN’s request for comment.
The game was being played without fans as punishment for crowd trouble 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 league defeats.
Suk, who rejoined Troyes from Reims last year, has scored 10 goals across 68 appearances in the French league.
