WBA world light heavyweight champion Danny Green has called a press conference for later Tuesday where he is expected to announce his shock retirement from boxing.

The 35-year-old, who had been due to defend his title in Perth for the first time next month, is believed to have made his decision over the weekend, and will hold the conference at Perth's Observation City hotel after returning from Sydney.

He had been there preparing for the mandatory defence Argentina's Hugo Garay on April 27, after taking the title from Croatian Stipe Drews in December last year.

An unabashed family man, Green and wife Nina had their second child, Archie, six days after Green fulfilled his long-stated promise to win a world title in front of his home crowd.

Family considerations are likely to have been a major consideration in Green's decision.

And Green's apparent decision to hang up his gloves will mean there will no be no rematch with long-time rival and verbal sparring partner Anthony Mundine, costing both men millions of dollars.

After first coming to public prominence at the 2000 Sydney Olympics, Green turned professional in 2001, winning his first 16 fights before suffering a controversial fifth round disqualification loss to Germany's Markus Beyer in a WBC world title challenge in August 2003 in Nuremberg.

Green won the WBC interim super middleweight belt with a sixth round stoppage of Canadian Eric Lucas in Canada four months later.

He suffered a second loss to Beyer in March 2005, dropping a majority points decision in Zwickau.

Green subsequently severed ties with his trainer and former triple world champion Jeff Fenech and hired Cuban trainer Ismael Salas.

His long-awaited domestic clash with Mundine finally eventuated in May 2006 when he suffered a unanimous points loss in a bout at Sydney's Aussie Stadium attended by around 30,000 spectators.

Green then decided to move up to the light heavyweight division and scored inside the distance wins over old rival Jason DeLisle, Paul Murdoch and Otis Griffin, before getting a world title crack at Drews.

The Australian totally dominated the bout against a surprisingly passive opponent, achieving his world title dream by earning three lopsided scores on the judges' cards.
