Hamilton accepts eight-year ban

One-time Olympic gold medallist Tyler Hamilton has accepted an eight-year doping ban, marking the end of a career tarnished by drugs.

The US Anti-Doping Agency meted out the penalty on Tuesday, two months after Hamilton admitted taking a product to battle depression that contained a steroid.

"I took a banned substance so I need to take whatever penalty they will give me and move forward," Hamilton said in April, when he announced his retirement from the sport.

Hamilton, 38, tested positive for testosterone or its precursors in an out of competition test on February 9, USADA said in a statement. "Mr. Hamilton has agreed to the lab findings and has acknowledged that this constitues his second offense," USADA said.

The 2004 Olympic time-trial champion, who formerly raced with Lance Armstrong's US Postal team, became the first athlete to be found guilty of doping by blood transfusion later that year. The American was subsequently suspended for two years. Even if he changed his mind about retiring, another return after this ban seems virtually impossible. Colorado, AFP
