Australia flanker Michael Hooper has been cited for an alleged act of foul play during his side's 33-13 win over England at the weekend.
Towards the end of the first half at Twickenham, referee Romaine Poite awarded the hosts a penalty against Hooper for charging at Mike Brown without the use of his arms.
The 23-year-old has now been called to a disciplinary hearing in London tomorrow, where if found guilty of breaking the rules, he will be suspended for the upcoming Rugby World Cup pool encounter against Wales.
The offence tends to carry a two-week punishment, which if enforced, would also rule Hooper out of his nation's quarter-final tie.
