Crusaders face anxious wait

The Champions could be without the service of All Blacks duo Ryan Crotty and Sam Whitelock for the upcoming Super Rugby fixture against the Highlanders.

Both suffered head knocks during the 19-29 defeat and was forced to leave the field after failed HIA (Head Injury Assesment) in the first 10 minutes of the match.

The duo now faces the usual protocol to prove they can play the Highlanders this weekend, however, if they are ruled out it means the Crusaders will be without seven All Blacks for the New Zealand Derby.
