Wayward Rebel Danny Cipriani is so far off-side with his Melbourne teammates, they voted him off the plane for their Super Rugby tour of South Africa.

The players, as well as management, said on Monday they had lost confidence in the former England Test five-eighth after his latest disciplinary breaches and didn't want him in their line-up.

The club has been reluctant to comment on Cipriani but issued a statement that revealed why he wasn't chosen in their 26-man squad, which departs Melbourne on Tuesday ahead of their clash with the Bulls in Pretoria on the weekend, followed by the Cheetahs the following round in Bloemfontein.

"The playing group and management have lost confidence in Danny after the latest in a series of off-field breaches of the team's behavioural standards," said Rebels chief executive Ross Oakley.

It was initially believed the 23-year-old, as well as teammate Richard Kingi, were stood down from last Friday's clash with the Queensland Reds because they had breached a team curfew after the loss to NSW the preceding round.

However Oakley revealed Cipriani, who was also in trouble back in February when he was ejected from a Melbourne nightclub around 3am after allegedly taking a bottle of alcohol, offended further.

"To put the decision in context, Danny also chose to stay out late again the night after the incident in Sydney, and did not attend training the following day," Oakley said.

"Management is addressing these issues with Danny and we support the decision to not allow him to join the tour to South Africa."

The revelation casts further doubt on the future of Cipriani at the new Super Rugby club, which prides itself on its culture and had players sign up to a five-star pledge along with their initial contracts.

He originally signed a two-year deal which he said last month he wanted to play out - however the Rebels may have other ideas.

Cipriani is expected to remain in Melbourne and continue training over the next two weeks.

He will also be expected to carry out "community engagement" with local clubs and schools.

All members of the touring party, including injured backs James Hilgendorf and Mark Gerrard as well as Kingi, came through the Rebels' final training session.
