All Blacks midfield back Sonny Bill Williams will play for the Chiefs in next year's Super 15 after re-signing with the New Zealand Rugby Union for one year today.
The 14-test All Black makes the move from the Crusaders after playing 15 matches for the Super 15 finalists last season.
It is a big coup for the Chiefs who also signed All Black first five-eighth Aaron Cruden during the off-season after losing experienced backs Mils Muliaina and Stephen Donald to overseas contracts.
The NZRU say specific details of William's contract are confidential, however he retains the option to take part in a limited number of professional boxing fixtures.
The former league international has previously played for French club Toulon and for Canterbury in the ITM Cup. He's also had four professional boxing bouts since 2009, winning all of them including two by knock-out.
