All Black Sonny Bill Williams is set to make a return to the boxing ring just months before the Rugby World Cup, according to reports.

Williams, who made his test debut on the All Blacks recent end of year tour, will hold a press conference in Sydney tomorrow to announce details of the upcoming bout, the Sydney Morning Herald reports.

Williams last entered the ring in July, knocking out fellow New Zealander Ryan "Hulk" Hogan in an undercard to Anthony Mundine's bout against Argentine Carlos Aden Jerez.

The All Black backline utility was in Mundine's corner when he suffered a shock fifth round knockout against Garth Wood last week.
