The Australian rugby union authorities have ended Israel Folau's contract over a social media post in which he said "hell awaits" gay people, BBC reports.
He has 48 hours to accept his sacking, or face a code of conduct hearing.
Rugby Australia said the 30-year-old "had committed a high-level breach of the Professional Players' Code of Conduct warranting termination of his employment contract".
He has won 73 caps and was expected to play at this year's World Cup in Japan.
Full-back Folau, who signed a four-year deal with Sydney-based Super Rugby side the Waratahs in March and had a contract with Rugby Australia until 2022, escaped punishment for similar comments last year.
Rugby Australia chief executive Raelene Castle said: "Israel was warned formally and repeatedly about the expectations of him as player for the Wallabies and NSW Waratahs with regards to social media use and he has failed to meet those obligations
