Serie A has announced that no action will be taken against Cagliari after Blaise Matuidi's claims of racist abuse during Juventus's 1-0 win over the Sardinians on Saturday.
The French midfielder took to social media to say that he had "experienced racism during the match" and that "weak people try to intimidate with hate".
However, the Italian league claims that it cannot take any action because the referee and match observers did not hear the racial abuse.
Federico Bernardeschi scored the winner in the second half as the Bianconeri recorded a sixth win in seven games to head into the two-week winter break one point behind table-topping Napoli.
The game came just two days after Hellas Verona received a suspended partial stadium ban and fine for a section of their fans racially abusing the 30-year-old in Juve's 3-1 away win on December 30.
