New York, Jan 16 : The World Anti-Doping Agency (WADA) has claimed Lance Armstrong would need to admit to doping under oath to get his lifetime cycling ban removed following the American's confession on Oprah Winfrey's no-holds-barred chat show.

WADA claimed it read the media reports about Armstrong confessing to doping in Winfrey's talk show on Monday, Nypost. com reports.

According to reports, Armstrong wants to make a comeback in cycling in the recognized triathlon events.

However, WADA claimed until and unless Armstrong reveals all about his doping scandal to them they can't life the cycling ban on him.

WADA said Armstrong must tell the relevant authorities each and everything he knows about doping, including the name of his apprentices in the scandal and also tell them which other cyclists were involved in doping.

Meanwhile, on Wednesday Winfrey revealed that an emotional Armstrong confessed to doping his way to cycling glory during an intense 2 1/2-hour chat session. (ANI)
