Australia captain James Horwill has been cited for an alleged incident in his side's defeat to the British and Irish Lions on Saturday.
The Wallabies skipper allegedly stamped on Lions lock Alun-Wyn Jones in an altercation in the third minute during the first Test in Brisbane.
The 28-year-old has been cited under Law 10.4 b, stating "a player must not stamp or trample on an opponent."
Horwill will appear for a judicial hearing later today.
