The new All Blacks midfield star Sonny Bill Williams is set to return to the boxing ring just months before next year's Rugby World Cup.
Willams will hold a media conference in Sydney tomorrow to announce the details of the fight.
Under his contract with the New Zealand Rugby Union he can have two bouts, the first of which was in June in Brisbane when he took just two and a half minutes to beat fellow New Zealander Ryan Hogan.
The New Zealand Rugby Union's refusing to comment on the matter until after tomorrow's announcement.
