LONDON, England (Reuters) – British Olympic champion Mo Farah said yesterday he had no tolerance for anyone who broke the rules after his former coach Alberto Salazar was banned for four years for doping violations.

The U.S. Anti-Doping Agency (USADA) said Salazar’s punishment was for “orchestrating and facilitating prohibited doping conduct” as head coach of the Nike Oregon Project (NOP), a camp designed primarily to develop U.S. endurance athletes.

“I’m relieved USADA has completed their investigation into Alberto Salazar. I left the Nike Oregon Project in 2017 but I have no tolerance for anyone who breaks the rules or crosses a line,” said Farah in a statement to Sky Sports News.

“A ruling has been made and I’m glad there has finally been a conclusion.”

Salazar stopped coaching Farah, double Olympic champion at both 5 000 and 10 000 metres, in 2017, when the runner decided to move back to England. The Briton said at the time that the doping investigation was not the reason they parted ways.
