Alberto Salazar – Mo Farah’s former athletics coach – has been banned from the sport for four years after being found guilty of doping violations.
Salazar runs the Nike Oregon Project – home to British four-time Olympic champion Farah from 2011 until 2017.
The decision follows a four-year investigation by the US Anti-Doping Agency (Usada) and a two-year court battle behind closed doors.
American Salazar said he was “shocked” by the outcome and would appeal.
“The Oregon Project has never and will never permit doping,” the 61-year-old added. “I will appeal and look forward to this unfair and protracted process reaching the conclusion I know to be true.”
Dr Jeffrey Brown, a Nike-paid endocrinologist who treated many of Salazar’s athletes, has also been banned for four years.
Farah split with Salazar in 2017, which the BBC can reveal was the same year the coach was first charged by Usada.
The 36-year-old, also a six-time world champion, said: “I’m relieved that Usada has, after four years, completed their investigation into Alberto Salazar.
