The Badminton World Federation has frozen the world rankings while the circuit is suspended.
The rankings have been backdated to March 17. That was the day after the last international tournament, the All England Open. They will be the basis for entry and seeding into the next international tournaments, whenever they are.
The world circuit is suspended to the end of April, but the BWF expects more tournaments to be put off in May and June.
It says it has yet to decide how the rankings will be unfrozen.
The BWF says "it is difficult to outline the exact procedure until we have an exact overview of what the international calendar will look like once play resumes and suspended tournaments have been rescheduled."
With the Tokyo Olympics delayed until 2021, the BWF says it is reviewing the Olympic qualification process. It notes the consequences of freezing the world rankings does not apply to Olympic qualifying.
