( CNN ) -- Johan Bruyneel has become the first victim of a United States government investigation into Lance Armstrong and doping . Armstrong was part of `` the most sophisticated , professionalized and successful doping program that sport has ever seen , '' the U.S. Anti-Doping Agency said Wednesday in releasing more than 1,000 pages of evidence in the case . Evidence of Armstrong doping 'overwhelming , ' agency says . Bruyneel , who was a close confidante of Armstrong during his seven Tour de France wins , has left his post as general manager of RadioShack by mutual agreement . Bruyneel was named in the USADA report which alleged that he was involved in helping Armstrong organize doping within the US Postal Team . `` From this day on , Johan Bruyneel will no longer act in the position of general manager of cycling team RadioShack Nissan Trek , '' a statement said on the team 's website . But Bruyneel says he is disappointed with the way he has been treated and says the USADA may have harmed his chances of a fair trial . `` I am surprised and extremely disappointed that USADA released information in the public domain relating to their pending case against me before I had been given any opportunity to review the evidence and provide my defence against it , '' he told AFP . `` I still hope to be able to defend myself in a forum free from bias , although I now fear that USADA 's calculated action may have irreversibly prejudiced my case . `` It is a troubling facet of USADA 's approach to this case that it appears not to respect basic principles such as the right to be heard and the presumption of innocence . '' The Belgian was Armstrong 's team manager when the Texan won his seven tour victories between 1999-2005 . Lance Armstrong 's legacy may withstand accusations . He also worked alongside Armstrong in 2009 and 20010 following his three-and-a-half year spell away from cycling . Bruyneel along with team doctor Pedro Celaya and team trainer Jose `` Pepe '' Marti will all receive a hearing before an independent judge to fight the charges following the report . Bruyneel 's departure comes after RadioShack rider Fabian Cancellara claimed he was close to leaving the team following the report . `` Johan 's name is cited 129 times in the report , '' Cancellara was quoted as saying by the Belgian newspaper Het Laatste Nieuws . `` I do n't know if I can still work with Johan . We 'll see what happens next . I want to know what happened . ''
He assumed role as general manager of RadioShack following USADA report . Belgian was Armstrong 's general manager between 1999 - 2001 . Unable to fight charges in court before independent judge . Fabian ##i admitted he may no longer be able to work with Bruyneel .
