Neil Black will stand down from his role as UK Athletics performance director at the end of October, the governing body has announced.
Black had said he would consider his position after coach Alberto Salazar was banned for four years by the United States Anti-Doping Agency.
Speaking after Salazar was banned, Black said: “I’ll be personally reviewing thoughts that I had, the decisions I’ve made, the things that I’ve said.
"Having done that thoroughly, patiently, sensibly, I’ll come to my own decision and that will run in parallel with discussions with UKA chair Chris Clark and the board.”
Salazar was found to have trafficked testosterone and falsified athlete medical records. Black defended Salazar's work as a consultant to the British team after a BBC investigation of Nike Oregon Project (NOP) was broadcast in 2015.
Black will still oversee Sir Mo Farah's involvement in the Chicago Marathon as planned this weekend.
A statement from UK Athletics read: "UK Athletics have announced that Neil Black will leave his role as performance director at the end of October.
"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."
