Paralympic cycling champion, Michael Gallagher, has been suspended after testing positive for banned substance EPO, a development which has now ruled him out of the Rio Games.
It was reported that the Scotland-born Australian won track gold in Beijing 2008 and London 2012.
The Australian Sports Anti-Doping Authority said he would not be allowed to compete in Rio while it investigates.
ASADA said the 37-year-old failed an out-of-competition test at a training camp in July.
The Paralympic Games will start on Wednesday and end on September 18.
