Johannesburg - Cyclist Pieter Seyffert returned an adverse analytical finding in an in-competition test conducted by the SA Institute for Drug-Free Sport (Saids) on February 17, according to Cycling South Africa.
The analytical report confirmed the presence of the stimulant Phentermine in his urine sample.
Seyffert, therefore, had been provisionally suspended with immediate effect from competing in any event, allowing the Saids process to take its disciplinary course, Cycling SA said in a statement on Thursday.
CSA said it respected the findings and would not stand in Saids' way as the investigation into the allegations began.
"Cycling South Africa respects the independence of the Saids process and will respect the outcome," the statement said.
"Cycling SA further reiterates its zero-tolerance approach to doping in sport and will continue working with Saids in the promotion of a drug-free sport via its awareness programmes and extensive testing."
