The Union Cycliste Internationale (UCI) announces that the Court of Arbitration for Sport (CAS) has dismissed the appeal filed by Carlos Oyarzun against the decision rendered by the UCI Anti-Doping Tribunal on 16 September 2016. The CAS confirmed that Mr. Oyarzun committed an Anti-Doping Rule Violation and upheld the four-year sanction imposed on him.
The matter resulted from the analysis of a sample provided by Carlos Oyarzun during the Pan American Games on 15 July 2015, which revealed the presence of FG-4592.
