TEXAS — Lance Armstrong could face the prospect of jail time and the repayment of millions of dollars following his reported admission that he used performance-enhancing drugs during his cycling career, legal experts said. Report by Reuters

And the fallout from his confession to American talk show host Oprah Winfrey could also threaten the sport that made him rich and an inspiration to millions of people, with a top Olympic official warning about the sport’s future at the games.

Already banned for life and stripped of all his race wins, including his seven Tour de France victories, Armstrong’s problems may only just be starting.

CBS Television reported on Tuesday that the disgraced rider had offered to pay more that $5 million to the US government in compensation for an alleged fraud against the US Postal Service, which for years sponsored his cycling team.

The network also said he offered to co-operate as a witness in a US investigation, but the Department of Justice turned down his request, raising the prospect that he could yet serve time in prison.
