The Diamond League season has been pushed into an August start by the coronavirus pandemic under a new calendar for track and field's showpiece meetings released Tuesday.
With the exception of a June 11 meeting in Oslo that will feature modified events in line with social distancing rules, the season proper is now scheduled to start in Monaco on August 14.
Twelve meetings will feature, culminating in China on October 17 at a venue yet to be arranged.
The London Diamond League meeting scheduled for July 4-5 has been cancelled.
Announcing that decision, UK Athletics chief Joanna Coates said: "We must place the safety of the entire athletics family at the forefront of every decision we make during these unprecedented times and ensure we are following government advice."
