More than one year after he was stripped of his seven Tour de France titles, Lance Armstrong's trophy case got a little smaller this week.

The 41-year-old Armstrong tweeted Thursday that he had sent his 2000 Olympic bronze medal to the United States Olympic Committee.

Patrick Sandusky of the USOC confirmed that the organization received the medal:

Armstrong, who acknowledged doping during his career in an interview with Oprah Winfrey in January, was officially stripped of the medal by the International Olympic Committee earlier this year.
