The World Athletics Indoor Championships in Nanjing, China have been pushed back again to March 2023 due to the COVID-19 pandemic, the sport's global governing body said on Thursday.
The event was initially scheduled for March 13-15 this year but was postponed for 12 months over fears related to the spread of the coronavirus in China.
Organisers have now agreed to host the Nanjing event a year after the 2022 championships in Belgrade, World Athletics added.
"For the safety of our athletes and technical officials, we must duly consider the risks in bringing a large group of people to attend the event under the pandemic situation and fully respect and carry out the pandemic prevention policy of the host country," World Athletics said in a statement.
"The indoor season for athletics falls within a narrow calendar window [up to the end of March] so it is not possible to extend the event to later in the year."
