Captain Sam Whitelock

Underdone All Blacks captain not concerned

Whitelock, who is making his 97th test appearance and is standing in for regular captain Kieran Read, has not played since May 12 due to concussion symptoms.

"I've had a couple of weeks where I haven't played," Whitelock said. "It's frustrating, I always want to be out there if I'm 100 percent fit or even if I'm not.

"At times I'm going to be blowing hard but I think that's normal no matter where you are in a test match."
