US cyclist Lance Armstrong will be interviewed by chat show host Oprah Winfrey, amid reports that he might publicly admit to doping.

Armstrong was stripped of his seven Tour de France titles by the sport's governing body, following a report by the US Anti-Doping Agency (Usada).

Winfrey's OWN network said the 90-minute interview would address "years of accusations of cheating".

Armstrong has maintained his innocence as he received a life ban from Usada.

But the New York Times reported on Friday that the 41-year-old was considering a public admission that he used banned performance-enhancing drugs. An admission could lead to an apparent bid to return to competing in marathons and triathlons, the paper reported.
