Rugby sevens and golf face one last test tomorrow night if they're to be included in the Olympics from 2016.
The International Olympic Committee's executive board voted to include both at a meeting two months ago.
But the recommendation must be rubber-stamped by a full meeting of the IOC congress in Copenhagen.
All Blacks great Jonah Lomu and top golfers Padraig Harrington and Michelle Wie will be part of their sport's final presentations.
One of the main issues has been whether top players will compete in the Olympics when they already have a full schedule, but world golf number one Tiger Woods says he'd play in an Olympics.
