The eldest Whitelock brother is leaving the Crusaders at the end of the Super Rugby season.
George Whitelock has confirmed he's moving to Japan to the play for the Panasonic Wild Knights.
The 28-year-old is one of the most capped Crusaders players and has been the Canterbury ITM Cup captain since 2009.
He first played for the Crusaders in 2008, paving the way for his three younger brothers Adam, Sam and Luke to follow.
Crusaders coach Todd Blackadder said George Whitelock's contribution to red and black rugby cannot be underestimated.
