The governing body of Australian rugby has condemned an anti-gay post by Wallabies fullback Israel Folau on social media, saying it is “unacceptable” and “disrespectful.”

Folau, one of the sport’s top players, published a message on his Instagram account that said “drunks, homosexuals, adulterers, liars, fornicators, thieves, atheists, idolators. Hell awaits you.”

Rugby Australia said its integrity unit was looking into the matter, and an announcement was expected Thursday. Folau’s comments come just five months before the start of the Rugby World Cup in Japan, where Folau is expected to be one of Australia leading players.

RA said “the content within the post is unacceptable. It does not represent the values of the sport and is disrespectful to members of the rugby community.”
