The Cycling Anti-Doping Foundation (CADF) admitted it had no case against Jakob Fuglsang, who was accused of links with disgraced doctor Michele Ferrari.
Fuglsang was the top performer in last season’s spring classics, winning Liege-Bastogne-Liege.
CADF said it had received information suggesting a link between Ferrari and Fuglsang, who has never failed a doping test, but had been unable to produce any evidence.
“The CADF received information in relation to alleged potential anti-doping rule violations and requested intelligence service provider Sportradar to conduct additional research on the allegations to complete CADF files,” it added.
“After careful review of the elements available, the CADF has not submitted the report to the International Cycling Union for the initiation of disciplinary proceedings against the individuals or team in question.”
“I have no case to answer. I am extremely concerned that such rumours could be spread out in the press,” Fuglsang said in a statement after the report.
A leaked CADF report was published Sunday by Danish newspaper Politiken suggesting the Italian doctor Michele Ferrari had visited Fuglsang in Monaco.
Ferrari was banned for life by the United States Anti-Doping Agency (USADA) for his relationship with the disgraced Lance Armstrong, who was also kicked out of the sport and stripped of his seven Tour de France titles after he admitted doping.
