All Blacks coach Graham Henry does not even know how Richie McCaw’s foot will hold up in the quarterfinal match with Argentina on Sunday.

Speaking after naming his run-on team, Henry said that come Sunday he will be able to say something since McCaw has been rested in two of the pool games.

Henry was asked whether wing Richard Kahui and fullback Israel Dagg have been rested knowing that Argentina is the weakest of all the quarterfinal qualifiers, he said that this is sudden death rugby and they have some surprises in the lineup.
