Neil Black is to stand down as performance director of British Athletics at the end of the month, the governing body announced on Tuesday
Black had been reported by British media to be considering his position after the U.S. Anti-Doping Agency (USADA) handed down a four-year ban to American Alberto Salaza - the former coach of Britain's Mo Farah.
While there is no indication of any wrongdoing on Black's part, he has been a supporter of Salazar, who was a British Athletics consultant until 2017 and who Black once described as a "genius".
A statement from British Athletics said: "Neil will commence a detailed handover with performance staff until his departure and will fulfil his role supporting Mo Farah at this weekend's Chicago marathon".
Britain won five medals at this month's world athletics championships -- its worst total since Helsinki 2005.
