All Blacks mid fielder Sonny Bill Williams has announced details of his next boxing bout, which will take place during the Super 15 season.

Waitakere’s Trusts Stadium will host the bout on June 5th with the opponent yet to be determined.

The fight will take place during round 16 of the Super 15, the same week the Crusaders have the bye.

Williams will personally donate $100,000 to the Red Cross Appeal.

All proceeds from the pay per view bout will also go to the appeal.

Williams is unbeaten in his previous three fights and will play for the Crusaders against the Bulls on Saturday at 7.35pm.
