The Crusaders could be without three of their key All Blacks in Saturday's Super Rugby match against the Hurricanes.
Kieran Read and Dan Carter are almost certain this miss the match while Israel Dagg is also doubtful.
Carter's struggling with a hamstring tear picked up against in the second test against Ireland ten days ago.
He says he'll make sure it's fully recovered before attempting to return.
"It's normally a few weeks but I take these things week by week and obviously got a plan in place for this week, if I get through that without any problems then you move onto next week.''
