Lance Armstrong is considering whether to publicly confess to doping, according to the New York Times.
The paper claims the 41-year-old could admit to the findings of a report by the United States Anti-Doping Agency.
The agency found Armstrong and his US Postal Service team had run "the most sophisticated, professionalised and successful doping programme that sport has ever seen".
He was stripped of his seven Tour de France titles and given a lifetime ban.
The BBC reports cycling's governing body, the International Cycling Union (UCI), accepted the findings and stripped Armstrong of all results since 1 August, 1998.
The Texan, who did not co-operate with the investigation and has always denied doping, has remained silent since the report although he opted not to appeal against the decision.
However, mention of his seven Tour wins was subsequently removed from his Twitter profile.
It is believed he is considering an admission because he wants to resume his athletic career, and has shown an interest in competing in triathlons.
