The 23-year-old, who started all of Ireland's RBS 6 Nations matches, is likely to be replaced by Ulster loosehead Court, although Declan Kidney could opt for the versatile Sale prop Buckley in New Plymouth.
Ireland expect Healy to be fit in time for the crunch clash with Australia on September 17 and have also been boosted by the return to fitness of Sean O'Brien, Gordon D'Arcy and Rob Kearney.
“Cian won't be playing at the weekend,” said Ireland team manager Paul McNaughton. “He won't resume contact work until the weekend, which was the original prognosis, so he won't be available for the USA game but will be available for the Australia game.
“He's been able to do a couple of scrums but not as much as normal.
“We're dealing from a full deck outside of Cian.
“Everybody else is fit and strong and available for selection, including Rob, Sean and Gordon D'Arcy.”
