Joost Van Der Westhuizen Ice Bucket Challenge

 I hope the All Blacks, the Springboks and the Wallabies take up the Challenge. Come on Teams - it's all for a good cause.

AND a big well done to Joost

 Meanwhile, both the All Blacks and Wallabies camps today responded to the challenge issued to them by former Springboks halfback Joost van der Westhuizen.

The former South African No 9, who was diagnosed with motor neuron disease in 2011 and can no longer walk, bathe or feed himself, completed the popular ice challenge before nominating the All Blacks, Wallabies and Springboks to do the same.

McCaw said he had not seen the challenge from van der Westhuizen but a few of the team had.

''It's a pretty terrible thing that he has had to deal with.

''Every day we are in the ice after training so ... we might have to do something like that. We are always up for a challenge.''

Wallabies coach Ewen McKenzie said they would also make sure they held their end of the bargain.

''We had a chat about that this morning. We've taken that on board and we'll work something out.''
