Wallabies and Rebels stars Kurtley Beale and Cooper Vuna have been sent home from South Africa following a fight on the team bus after a visit to a nightclub.
The Melbourne Rebels have confirmed that Beale and Vuna have both been stood down and will return to Australia immediately.
Head Coach, Damien Hill, said both Beale and Vuna had broken team protocols and as a result cannot be part of the team until the disciplinary process is complete.
"The Club will not tolerate this type of behaviour and I am embarrassed for everyone associated with building this Club," Hill said.
CEO, Steven Boland, said both Beale and Vuna are contracted Wallabies and as a consequence the Rebels have been liaising this afternoon with the ARU and will continue to do so in the best interests of the Rebels and Australian Rugby.
"There can be no excuses for the disrespect shown to the Melbourne Rebels Rugby Club by these players.
"The expectation of the Club and our supporters is that the management and players in South Africa focus immediately on their task of making amends for the poor on field performance in Durban on Saturday by making us all proud in Bloemfontein next weekend," Boland said.
The Rebels lost 64-7 in a ten try hammering to the Sharks on Saturday and allegedley went out to a Durban nightclub after the match and on the way back to the hotel the incident occured.
Winger Vuna alleged in a tweet that Beale hit him after he had tried to help him after he allegedley got into an argument with club captain Gareth Delve on the bus after he insisted that Beale put his shirt back on before the bus reached the hotel.
"I need to leave right now, this ain't for me! I tried to help someone but got punched so instead of putting him in hospital il leave!" Vuna posted.
The tweet was deleted but later published on a fan website, with one Twitter user asking Vuna if his alleged assailant was drunk.
Vuna replied: "Hmmmmm his name is kurtley_beale bloody grub!"
Beale did not play in the Durban match as he continues his recovery from hand surgery, while the Sharks game was Vuna's first competitive match this season after a shoulder injury.
Beale was granted bail last July to attend mediation after appearing in court charged with common assault.
He was allegedly involved in an altercation with a security guard after he and Wallabies team-mate Quade Cooper were refused entry to a Brisbane pub before Australia's first Test with Wales in June.
Beale is expected to undertake his first session of mediation next month.
