Fifa have confirmed they will investigate what led to Zinedine Zidane's extraordinary reaction to Marco Materazzi's comments during the World Cup final.
Several theories have been forwarded as to what the Italy defender said to provoke such an angry response from the France captain, who was taking part in his final game before retiring.
Materazzi has denied calling Zidane a "terrorist" and some sources claim he insulted the Frenchman's family.
"Fifa will open a disciplinary investigation into Zidane's conduct to enable it to clarify the circumstances surrounding the incident as exactly as possible," read a statement from the governing body.
If the Internazionale centre back is found guilty of making any racist remarks to Zidane, he can expect to be banned by the authorities.
Zidane was sent off for the offence and France went on to lose the final on penalties after their midfield maestro had gone closest to scoring in extra time when forcing a flying save out of Gianluigi Buffon.
