The Australian Rugby Union could pocket an estimated $1million if the Wallabies play a World Cup warm-up match against the USA Eagles in Chicago this year.

Fairfax Media understands the ARU and USA Rugby are in advanced talks around a September fixture. There is some discussion still around the venue and exact date, but it is believed the plan is for the match to be played at historic Soldier Field, home of the Chicago Bears, and the same stadium that hosted a sold-out clash with the All Blacks in November.

The game would serve as a warm-up match for both sides in the lead up to the World Cup in England and Wales, which starts on September 23.

It would also provide a financial buffer for the ARU while it waits for money to start flowing from a soon-to-be-announced broadcast deal believed to be worth $45 million a year to Australia.
