"Conrad Smith has returned to NZ to be with his wife who is expecting a baby. Ryan Crotty called into AB squad as cover," the All Blacks announced on their official Twitter feed.
The absence of 77-Test veteran Smith, who has forged a record-breaking centres partnership with Ma'a Nonu, is a major blow for the All Blacks as they chase a record-breaking 18th consecutive win.
Malakai Fekitoa is expected to start in his place, with Crotty on the bench.
