Trinidad and Tobago's Njisane Phillip lost his appeal at the Court of Arbitration for Sport (CAS) against a doping offence at the 2019 Pan American Games in Lima.
CAS confirmed the decision made by the Panam Sports Ad Hoc Disciplinary Commission on November 15 2019.
It determined that a prohibited substance was found in the cyclist's sample and subsequently his results from Lima 2019 were disqualified.
As a result, Trinidad and Tobago were stripped of their gold medal in the men's team sprint track cycling event, with Colombia moving up to top spot.
The final had been won at the Games by Nicholas Paul, Keron Bramble and Phillip.
Paul retained his gold medal in the individual sprint event, but Phillip was stripped of his silver medal in the same competition.
Despite the offence, Panam Sports claimed it did not believe Philip had any "intention of cheating."
"Panam Sports wishes to state that the prohibited substance found in the sample provided by Phillip is not considered a performance enhancing substance and believes that regardless of the award by the CAS that confirmed the decision of the Panam Sports Ad Hoc Disciplinary Commission, Phillip had no intention of cheating or having any unfair advantage over his competitors," a statement by the organisation said.
"Panam Sports believes that Phillip is an honest athlete that made a mistake and that he is committed to learn from the experience."
A lawyer representing Phillip criticised Panam Sports following the organisation’s publication of a revised Lima 2019 medal table in January.
Lawyer Tyrone Marcus claimed there had been a leak of information, which he alleges compromised the appeals process.
There were 15 positive tests at the 2019 Pan American Games from a total of 1,905 samples.
This included 1,652 urine and 253 blood samples.
