The three continental Para-badminton championships remaining on the 2020 calendar have been suspended due to the coronavirus pandemic.
The European, Pan-American and Asian tournaments were due to be held in October and November, but now join their African counterpart in being suspended.
Irish capital Dublin was the European venue, Manizales in Colombia was due to host competition between players from the Americas and Thai capital Bangkok was slated to host the Asian tournament.
Kampala in Uganda was supposed to stage the African competition in April, but that was suspended in March.
The Badminton World Federation (BWF) said that a decision on whether or not these tournaments would be part of the 2021 calendar was yet to be made.
Tournament hosts and continental bodies were consulted before the suspensions were decided, the BWF added, saying the health and safety of athletes, support teams and officials was its priority.
Para-badminton is due to make its Paralympic debut next year at the Tokyo 2020 Paralympics - postponed by 12 months due to the pandemic.
The 2020 Oceania Para-Badminton Championships took place in Ballarat in Australia in February.
