Ireland will reject any Willie Anderson-style challenges to the haka ahead of their test in Chicago, instead focusing on last-minute mental preparation.
Captain Rory Best will not lead his side into the kind of nose-to-nose confrontation that Anderson produced with All Black Wayne Shelford in 1989.
Ireland's players linked arms before that 23-6 Dublin defeat, advancing on the All Blacks mid-haka - yet Best insisted Joe Schmidt's men treat the ceremonial war dance with full respect but as a "sideshow".
"Because there have been a few incidents they don't allow you to go past the 10m line anyway," Best said. "So we'll just line up and I think everyone will deal with it in their own way.
"Some people will watch it, respect it. Other people will be looking at it but in their own head they'll be rehearsing their own roles. For me it will be going through plays to make sure that when the game kicks off I am in the best possible place to win the game for Ireland.
