Armstrong was also banned from cycling for life by the USADA.

CBS reports:

Tim Herman says he has no knowledge of Armstrong considering a confession, and told The Associated Press: "When, and if, Lance has something to say, there won't be any secret about it."

The New York Times reported Friday that Armstrong has told associates he is considering admitting to the use of performance-enhancing drugs.

The report cited anonymous sources and said Armstrong was considering a confession to help restore his athletic career in triathlons and running events at age 41. Armstrong was banned for life from cycling and cannot compete in athletic events sanctioned by the U.S. Anti-Doping Agency and the World Anti-Doping Agency.

Herman denied that Armstrong has reached out to USADA chief executive Travis Tygart and David Howman, director general of the World Anti-Doping Agency.
