Agreement is likely to be reached this week on a historic test between the All Blacks and US Eagles next November.
Final details are yet to be confirmed but, with both countries agreed the test has to be at an iconic stadium, it is believed Chicago or Washington will be the host city.
The former has the NFL's oldest stadium - Soldier Field with a capacity of 61,000 - while the capital boasts the enormous 91,000 capacity FedEx Stadium where the Washington Redskins play.
The New Zealand Rugby Union have been keen to play in the US for some time and efforts to arrange a game there stepped up this year following the arrival of the New York-headquartered AIG as a major sponsor of the All Blacks. The first weekend of November next year was the preferred date to allow the All Blacks to play en-route to their European tour; finding an appropriate venue and opposition proved challenging.
Building a temporary stadium at an iconic New York or American landmark was a possibility at one stage. One idea aired was to build a 20,000-seat temporary venue at Harvard University. The 83,000 capacity MetLife Stadium in New York - which will host the next Superbowl - would have been a spectacular (if challenging to fill) venue but it is believed it will probably be in use on the proposed Saturday and naming rights are held by a key rival to AIG.
