Australian rugby league Test stars Paul Gallen and Greg Bird have signed up to fight New Zealand rugby union players in a charity fundraiser in Auckland.
NSW captain Gallen and State of Origin teammate Bird will get into the ring for the Fight for Life boxing event in December, dubbed the "battle of the codes", to help raise money for prostate cancer awareness.
The pair will join former Australia international Willie Mason and 22-Test Kiwi Jarrod McCracken on the rugby league team for the bout.
Current Super Rugby players Hika Elliot and Rene Ranger, and former All Blacks Carlos Spencer and Troy Flavell will provide the opposition on December 15 at The Trusts Arena in Henderson.
Who will fight who has not been disclosed.
McCracken, 42, who was bankrupted last month after a dispute over a Townsville property development, agreed to fight after his 71-year-old father Ken was diagnosed with prostate cancer.
"My motivation is simple," said McCracken. "If I can convince blokes to go and get checked and save their kids from having to watch their father go through what the old man is going through now, then every second inside the ring would have been worth it."
Ranger, who last played for the All Blacks in 2010, says he has been given the green light by Super Rugby franchise the Blues to fight.
He is likely to tour the UK with the Maori All Blacks in November while Elliot is a contender to make the All Blacks squad for their end of year tour to the northern hemisphere.
