Rio de Janeiro - All Blacks legend Richie McCaw wondered whether he might be bringing bad luck after he watched New Zealand's shock 14-12 rugby loss to Japan, in which Sonny Bill Williams suffered a tournament-ending injury.
McCaw was also present when New Zealand's women's hockey team, which features his girlfriend, lost 2-1 to Germany.
"Perhaps I am," he said, when asked by TVNZ whether he was a bad-luck charm.
"I might have to leave!"
Williams limped off after eight minutes with a partial rupture of his Achilles, ruling him out of action for between six to nine months.
