"He's had an unlucky streak of injuries," wing Rieko Ioane said today. "They're the niggly ones which sit him out for a month and then he plays for a couple of weeks and then he gets another one, so it's been tough on him.
"The form that he's been in – we're going to miss that. He's been a powerhouse for us all year.
"He's been into our new boys about the expectations that are needed – they'll have big shoes to fill but I'm sure they'll do the job."
Loose forward Jerome Kaino said: "He calls our lineouts and has a lot of input into our forwards and team stuff. I've definitely seen the growth in him and he'll definitely be missed on the field."
The Blues, who haven't beaten a New Zealand team in 16 matches, will face a tough challenge against the All Black-laden forwards in the Crusaders at Eden Park.
The Crusaders will be bolstered by belief after coming back from a 29-point deficit to beat the Waratahs 31-29 last weekend and will know they probably won't get away with another poor start on Saturday.
