Holders Australia and New Zealand have withdrawn from this year's Rugby League World Cup in England, saying it is "simply too unsafe" to travel due to the coronavirus pandemic.
Australia, who have won the tournament a record 11 times, and 2008 champions New Zealand were due to head for the United Kingdom this autumn to take part in the tournament, which is scheduled to get under way on 23 October.
However, with Covid-19 infection rates in the host nation continuing to rise, the two southern hemisphere powerhouses have decided not to travel and repeated calls for the competition to be postponed until 2022.
A joint statement from the two nations said: "The Australian Rugby League Commission (ARLC) and New Zealand Rugby League (NZRL) today informed the International Rugby League (IRL) and Rugby League World Cup (RLWC) organisers that Australia and New Zealand will not compete in a 2021 World Cup because of player welfare and safety concerns.
"The ARLC and NZRL have again requested the RLWC2021 be postponed until 2022 to minimise risk of players contracting COVID-19 and ensure the best outcome for player well-being.
"The ARLC and NZRL have resolved, that in the present environment the risks to athletes and officials travelling to the UK to participate in the tournament this year are too great, and it is unable to endorse Australia and New Zealand participating in the RLWC in 2021."
NZRL chief executive Greg Peters cited "stark differences" between the management of the pandemic in the UK and Australasia and insisted it was "simply too unsafe" for the teams to take part in the tournament.
He said: "The safety and well-being of our people is the main priority, and unfortunately, that cannot be guaranteed to our satisfaction.
"There are stark differences between how the pandemic is being managed in the UK compared to Australasia and recent developments have highlighted how quickly things can change."
