Australia openside flanker Michael Hooper has been cited for alleged foul play during Saturday's Rugby Championship fixture against Argentina.
Hooper is alleged to have contravened Law 10.4 (a) Punching or striking, when he made contact with Argentina fly-half, Nicolas Sanchez in an incident that occurred in the 59th minute of the match between the Pumas and Wallabies.
The case is to be considered in the first instance by SANZAR Duty Judicial Officer Chris Morris.
All SANZAR disciplinary matters are in the first instance referred to a Duty Judicial Officer hearing to provide the option of expediting the judicial process.
For a matter to be dispensed with at this hearing, the person appearing must plead guilty and accept the penalty offered by the DJO.
