Trainer Tony Mundine has reportedly quit his son Anthony's camp just a month before the eagerly-awaited showdown with Danny Green.

Tony Mundine said all was not right in the camp which led to his decision to quit.

"(There were) a few things I didn't like. I want to quit ... and just concentrate on my life," he told the Nine Network.

The news is a major blow to the Mundine camp ahead of its much anticipated showdown with Green on May 17 at Aussie Stadium.

Tony Mundine has been by his son's side since his boxing career started in 2000 after the former rugby league player quit St George Illawarra.

Tony Mundine won Australian titles in four divisions and unsuccessfully challenged legendary Argentinian Carlos Monzon for the WBA middleweight title in Buenos Aires in 1974.

A shocked Anthony Mundine said he was hoping to meet with his dad to try to resolve their differences.

"Tempers flare, certain misunderstandings happen hopefully we can clarify this.

"It's upsetting ... hopefully he can put personal issues aside and think 'I got to be there for my boy'.

"If I have to go in there to do my thing without my dad I have to, it will be very sad," he told the Nine Network.
