New Zealand boxer Shane Cameron has missed out on an opportunity to fight for the world title against Australian Danny Green.
The IBO cruiserweight World Champion has announced he'll instead fight American Antonio Tarver.
Green will fight the former multiple light heavyweight world champion at the Sydney Entertainment Centre on July 20.
The West Australian declared he was totally over the appendix problem which required surgery in a Perth hospital back in January.
"My health is fantastic, I'm feeling in good condition," Green told a media conference today.
"I lost 13 kgs. To be honest, when I was lying in hospital, I didn't think that I would be able to fight again, which was obviously fairly scary for me.
"I've recovered well and put most of my weight back on and I'm in the process to go into a training camp in about four or five weeks to get ready for the toughest test of my career.
Last week, Shane Cameron's trainer Barry Michael told ONE News Green's best option was to fight the New Zealander.
"I've been a promoter for over 30 years and I really believe what the Cameron camp has offered Danny Green is a far better offer than what he could possibly do fighting Antonio Tarver in Australia," Michael said.
"They're going to bring out a guy out of retirement who's 42 years of age. I can't see it being credible to be honest."
However, Green believes taking on the American will be the toughest fight of his career.
"Antonio Tarver is a monster of a bloke and his credentials are impeccable."
Tarver, 42, (28-6) is dropping down after one fight in the heavyweight division.
Both Tarver and 38-year-old Green (31-3) have knocked out former multiple-division world title winner Roy Jones jr.
Tarver wasn't worried about Green's impressive knockout record and planned to arrive at least two weeks before the bout to ensure he's fully acclimatised and ready.
"I've faced punches before, they have to land in order to be effective so I'm not worried about that," Tarver said from the United States.
"I know Danny Green is going to bring his attitude, his aggression. He's a proud fighter, so am I. So this fight makes to be a great fight."
