Australia flanker Michael Hooper has been cited for an alleged act of foul play during their 33-13 Rugby World Cup victory over England on Saturday.
World Rugby confirmed that Hooper has been reported by independent citing commissioner Steve Hinds for allegedly "charging into a ruck or maul without use of the arms or grasping the player".
The incident happened a minute before half-time in the game at Twickenham, when Hooper challenged England full-back Mike Brown.
Hooper played a key role in the victory which means Stuart Lancaster's side cannot qualify for the knockout stages of the tournament.
Hooper will now face a disciplinary hearing in London on Tuesday, where his case will be heard by Independent Judicial Officer Alan Hudson, and could be ruled out of their final Pool A match with wales which will determine who tops the group.
The 23-year-old could be ruled out for the duration of the tournament, with sanctions for charging ranging from a two week ban at the lower end of the scale, through to five weeks if it is classed as mid-range, or 10 weeks and above if regarded as a top-end offence.
In a statement, World Rugby said: "Michael Hooper has been cited by independent citing commissioner Steve Hinds (New Zealand) for an alleged act of foul play contrary to law 10.4 (h) (charging into a ruck or maul without use of the arms or grasping the player) during the 39th minute of the Rugby World Cup 2015 Pool A match between England and Australia on Saturday, October 3.
"The hearing will take place at 1000 on Tuesday, October 6 at the offices of RWC official law firm Clifford Chance in London. The case will be heard by independent judicial officer Alan Hudson (Canada)."
Meanwhile, Australia winger Rob Horne's shoulder injury is not as bad as feared and he will stay in the Wallabies World Cup squad while it is treated.
Horne was taken off in the 11th minute of the 33-13 victory over England on Saturday that secured Australia's place in the quarter-finals and there were concerns the 26-year-old might join Wycliff Palu and Will Skelton in being sent home.
"We've had the reports back on Rob Horne and they were better than expected, so we're going to just sit on that and wait and see how it unfolds," said defence coach Nathan Grey.
"The medical staff will be doing all they can. Results were better than they thought, so they will assess day by day. Other than that, everyone is pretty good."
