Japan first-five Ryohei Yamanaka faces a two-year ban for rubbing on a hair-growth cream to try to grow a moustache, dashing his Rugby World Cup dreams.
Brave Blossoms head coach John Kirwan says he expects the International Rugby Board to throw the book at Yamanaka, which would rule him out of the World Cup.
Kirwan says he got a hair-growth cream to try and grow a moustache, which apparently had a steroid in it and he didn't know.
Yamanaka flew home from Asian Five Nations duty in Hong Kong last month after testing positive and Kirwan expects the potential ban will last for up to two years.
Japan are also competing in Pacific Nations Cup, which begins next weekend in Tokyo, and also features Samoa, Fiji and Tonga.
