FIFA said on Tuesday it would open a disciplinary investigation into the circumstances surrounding France captain Zinedine Zidane's head-butt on Italy's Marco Materazzi during the World Cup final.
'FIFA will open a disciplinary investigation into Zidane's conduct to enable it to clarify the circumstances surrounding the incident as exactly as possible,' world soccer's governing body said in a statement.
Italy won the final in a penalty shootout after Zidane was sent off for the head-butt.
