Boxing All Black Sonny Bill Williams promised on Saturday he would put in the hard yards to repay his big money transfer to Japan's Panasonic Wild Knights.
The 27-year-centre, who will earn around $1.2 million for his 12 weeks in Japan, sat out Panasonic's 44-13 win over Ricoh Black Rams in their Top League opener in Tokyo.
He is expected to make his debut on September 9.
