On-loan Juventus defender Medhi Benatia cut short a post-match television interview after claiming to hear a racist insult in his earpiece.
The France-born player, 30, was speaking to Italian broadcaster Rai after Saturday’s 1-1 draw with Torino.
“What stupid person is speaking?” said Benatia before ending the interview.
The incident comes a week after another Serie A player, Pescara’s Sulley Muntari, walked off the pitch after claiming he was being racially abused.
Benatia who plays for the Morocco national team has not commented publicly on what happened during the television interview.
The broadcaster has since apologised and promised to find out who made the “unacceptable” comments.
“Rai is sincerely saddened by the deplorable episode of racism involving the Juventus player during the broadcast of Champagne Football,” it said on Sunday, adding that the insult had not been heard by the viewers.
Benatia has made 17 league and cup appearances for Juventus, who are closing in on a sixth successive Serie A title and are in the Champions League semi-finals.
