Australia have lost a key player ahead of their year-end tour, following a disputed 31-28 win over the Barbarians on Saturday.
Flank Jack Dempsey has been ruled out of Australia's Northern Hemisphere tour with a serious leg injury.
Coach Michael Cheika was expected to announce his touring squad on Sunday for Test matches next month against Japan, Wales, England and Scotland.
There were reports the NSW Waratahs back row forward had badly torn a hamstring, but Cheika was reluctant to go into specifics.
"I don't think that would be an accurate assumption, it's so fresh," he told reporters.
"Whatever it is, it's serious. When I say serious, there's no doubt he'll be out of the tour.
"And he's in a fair bit of pain too, so let's just see what happens with it. It's unfortunate his season's over."
Dempsey has been one of Australia's best-performing players in recent weeks and on Saturday Cheika said the Wallabies could not have won without him.
The performance of New Zealand referee Brendon Pickerill was heavily criticized by BaaBaas coach Alan Jones afterwards - in what was one of the most extraordinary post-match sprays ever see.
