"He was in great shape and had been training very well."

Captain Andrew Hore is due to return from suspension after next week's bye, while former All Blacks lock Brad Thorn is expected to play.
Thorn suffered a minor calf injury during the preseason and sat out last night's match.
With the Cheetahs the next opponent for the Highlanders at Invercargill, Thorn will set a new Super Rugby record as the oldest player ever to be involved in the tournament.
