A former team mate of Lance Armstrong and now a coach with Cycling Australia, Matt White, has stood down following his admission that he took part in a doping ring.
White has admitted to being involved in doping during his riding career after being outed in the investigation documents which led to seven-time Tour de France winner Armstrong being banned for life.
One of the most influential figures in Australian cycling, White stood down from his posts as national men's road racing co-ordinator and selector and sports director for Australian professional road team Orica-GreenEDGE.
Cycling Australia president Klaus Mueller admitted his organisation could have made more thorough checks before appointing White, whose job future will be discussed at a board meeting later this week.
And he reiterated that an amnesty for Australian riders involved in doping during the period in which Armstrong's team dominated the sport needed to be seriously considered.
Armstrong teammate and disgraced Tour de France winner Floyd Landis' testimony outed White - the American saying he had shared testosterone and EPO with White in 2003.
Mueller said he spoke to White late on Saturday night and it was mutually agreed he would stand aside until Cycling Australia and Australia's anti-doping body ASADA had fully investigated the matter.
