The message came after a two-year battle in court and just over four years of scrutiny. The data on doping came first in the BBC program "Panorama" in 2015, which caused the Olympic and world champion to turn away from the media.

Salazar must have manipulated doping controls, used banned methods and made sure athletes got hold of the performance-enhancing substance testosterone. Cuban is the head of the Nike Oregon Project (NOP), which is a program designed primarily to develop American long-distance runners. Several of those included in it compete in the Doha Athletics World Cup.

However, no athletes' names are mentioned in the USADAS report. Salazar has repeatedly denied the allegations. Farah won 4 Olympic golds and 6 World Cup golds under him before the British left the program in 2017.
