Barrett is yet to be ruled out after he trained on Tuesday with a strapped ankle but the All Blacks goal kicker did not take part in the kicking session, suggesting some tenderness remains.
In positive news for the All Blacks, Beauden Barrett appears to have fully recovered from the horrific fall onto his neck in an ugly high ball incident that resulted in Springboks wing Kurt-Lee Arendse copping a four-week suspension for his reckless challenge.
All Blacks captain Sam Cane is thankful Beauden Barrett emerged unscathed.
"I speak on behalf of everyone... it was pretty frightening, nasty, to see," Cane said. "It's almost as bad as it gets. I don't know what Beaudy is made of – he's the rubber band man. I know it gave him a bit of a fright.
"Jordie has a bit of trouble with the ankle but they're tough boys."
Cane also moved to downplay the seriousness of Jordan's illness.
"I don't think he's too bad he's just got a bit of a mild stomach issue. He was at the gym yesterday afternoon so it can't be too bad."
Depending on Jordie Barrett and Jordan's availability the All Blacks may be forced to reshape their back three for their second crack at the Springboks.
