Paris: Code-hopper Jarryd Hayne, who made a surprise decision to jump from the NFL to rugby sevens, was no certainty to make Fiji’s final squad for the Rio Olympics, the team’s coach said on Sunday.

The 28-year-old Hayne, who spurned a lucrative contract in rugby league to try to break into the NFL last year, retired from the hugely popular North American sport on Sunday after he said the Fijian rugby sevens side had approached him about playing at Rio.

Fiji coach Ben Ryan, however, said there were no guarantees the former Australian rugby league international, who played one season for the San Francisco 49ers, would make his final cut for the August 5-21 Games.
