All Blacks receive Ryan Crotty and Sam Cane boost ahead of Argentina clash

New Zealand duo Ryan Crotty and Sam Cane have returned to the squad ahead of the Rugby Championship clash against Argentina on Saturday in Nelson after recovering from concussion injuries.

Both the players suffered the injury during the tournament opening clash against Australia in Sydney and completed a successful training on Tuesday.

All Blacks assistant coach Ian Foster confirmed the news on the duo but admitted that a final call on their inclusion for Saturday's game will be taken on Thursday when the matchday23 squad will be named.

"They've come through training today really well and both participated at a decent level, so we'll just assess that in the next couple of days. But it was pleasing to see their involvement," assistant coach Ian Foster said on Tuesday.

"At this stage they're where they need to be in terms of all the protocols that we have to follow through. The fact they've trained well today means we'll assess them tomorrow and make a final decision then. So they're where they need to be today".

Foster also stressed on the importance to continue winning games and maintain the momentum heading into the World Cup 2019.

"We are aware of a 12-month plan and how we mange players, but we don't want to lose a test match and we don't actually want to play poorly in a test match, so that's probably paramount in our mind," said Foster.

New Zealand currently occupy the pole position in the Rugby Championship table with 10 points from two games.
