Doha Diamond League, the 5th of the series has been scheduled for 9 October after it could not be held as the traditional season opener in April, but will now take place instead on 25 September.
The plan is to stage 12 disciplines. A list of athletes who will compete in the Qatari capital will be announced in due course.
Due to the ongoing global health situation and ever-changing COVID-19 regulations, the 2020 Diamond League calendar remains provisional and subject to further changes.
Following exhibition events in Oslo and Zurich earlier this summer, the competitive season is set to begin in Monaco on 14 August.
The 2020 Wanda Diamond League will not be a structured series of events leading to a final as is usually the case. Athletes will therefore not earn Diamond League points this season, and there will not be a single, 24-discipline final in Zurich as originally planned.
