Planning is underway for an American Football combine in Sydney next year which is hoping to attract some of the biggest US scouts and coaches and uncover the next Jarryd Hayne.

Organisers plan to scour the country to unearth diamonds in the rough who could make it in the NFL, from rugby league, rugby union, Australian rules and soccer .

Australian former NFL player Colin Scotts is putting together the event which is expected to be held at ANZ Stadium in August.

Players will be tested for speed, strength and agility in front of coaches and scouts from American and European franchises.
