Sonny Bill Williams won't be swayed by his Crusaders and All Blacks team-mates Richie McCaw and Dan Carter re-signing with the New Zealand Rugby Union.
Speaking to a 50-strong media contingent ahead of his fourth professional boxing bout in Auckland on Sunday and flanked by fellow boxers David Tua and Anthony Mundine, Williams wouldn't be drawn on his future beyond the Super 15 and the World Cup.
Williams says he's got to do what's best for himself and his family but insists he wants to keep boxing no matter what his rugby future.
