As world champion Buvaysa Saytiev of Russia and Murat Gaidarov left the mat they appeared to exchange heated words and punches, triggering a melee that delayed the competition for several minutes.

The International Wrestling Federation (FILA) said the athletes and federations faced sanctions and a possible 10,000 dollar fine.

"I have issued both delegations warnings and both athletes and federations face the possibility of sanctions and a minimum fine of 10,000 dollar depending on the findings of the disciplinary committee," said FILA president Raphael Martinette.

Resembling a scene from professional wrestling, the officials appeared uncertain what to do as spectators quickly joined the scuffle and members of both teams swung wildly at each other.
