A recurrence of a hamstring problem has forced the All Blacks first five Dan Carter to withdraw from the Crusaders side to play the Chiefs, in Mt Maunganui, on Friday.
Carter was initially named in the starting lineup having missed last week's win over the defending champions, the South African the Bulls with a hamstring injury.
He felt the hamstring tighten halfway through training today and immediately left the field.
He will be reassessed early next week over his availability for the Crusaders next match, which is against the Highlanders in Nelson.
matt Berquist will replace Carter in the side.
