Star forward Taulupe Faletau will be among four players missing when if Wales host the All Blacks in October.
As reported by the Herald last week, the All Blacks could play two additional money-spinning tests this year in Wales and the United States.
Proposals for the All Blacks to play Six Nations champions Wales on October 30 at Cardiff's Principality Stadium and the USA on October 23, potentially at the new 70,000-seat Allegiant Stadium which opened last year for the Las Vegas Raiders NFL team, have been presented to the New Zealand Rugby board.
However the match in Cardiff has taken a blow to its credibility with Faletau and fellow England club players Dan Biggar, Louis Rees-Zammit and Callum Sheedy set to miss the clash.
The match falls outside the official autumn International window so they do not have to be released by their clubs.
