All Blacks captain Richie McCaw knows retirement is coming but won't say whether it will be after next year's World Cup in England.
The champion flanker will leave a huge hole in the All Blacks when he finally calls it a day but there's still some life left in the legs of the 33-year-old who has played 134 test matches since making his debut against Ireland in 2001.
McCaw sat out Sunday's victory over the US in Chicago but should make his first appearance on the end of year tour against England at Twickenham this weekend.
The Crusader was recently pressed on his playing future by British newspaper The Guardian but said there was no timeline for his eventual retirement.
"To say I'm going to give it up or carry on playing, I just don't know," McCaw told The Guardian. "You don't want to give up something you love like that. But, you know, one day the time will come. Whether it's next year or the year after, I'm not sure."
