The former chief of Australia's own anti-doping authority has poured cold water on Jarryd Hayne's new dream of playing Rugby 7s for Fiji at the Rio Olympics.
Former ASADA boss Richard Ings responded to news Hayne had quit the NFL to join the Fiji camp as early as this week ahead of the London Sevens by questioning his eligibility to even play.
Ings stated Hayne would be unlikely to play any professional sport, including rugby sevens, for at least six months pending time spent in a registered drug-testing pool.
The NFL does not comply with the world anti-doping agency's code, meaning any player looking to switch from American football must first undergo intense drug screening before being deemed able to play professional sport elsewhere.
Ings said this morning he expected World Rugby Sevens to step in and veto Hayne's Rio bid.
