The South China Morning Post reported the prestigious Hong Kong Sevens tournament, which hosts 40,000 people each day and was scheduled for April 3-6, has been shelved for six months due to on-going health fears in the city.
The Hong Kong Sevens has run every year since 1976 and was due to host its 45th event, where the Black Ferns and All Blacks sevens were due to compete.
The South China Morning Post reported the event would likely be postponed until October.
An official announcement from World Rugby is expected later today.
The news comes after Hong Kong Rugby Union chief executive Robbie McRobbie last month issued a statement saying the sevens event would proceed as planned.
