American gymnast Jordan Chiles recently lost her bronze medal in the individual floor exercise at the Paris Olympics due to a timing technicality in her coach's appeal. The medal will now go to Ana Barbosu of Romania, following a ruling by the International Olympic Committee. This is not an uncommon occurrence in Olympic history, with several other U.S. Olympians having had to return medals, often due to failed drug tests or banned substance use. One notable case involves Jim Thorpe, who had his medals stripped due to violating amateurism rules after previously playing professional baseball. Lance Armstrong also returned his bronze medal from the 2000 Sydney Games after admitting to using performance-enhancing drugs. Similarly, Marion Jones was stripped of her medals after admitting to drug use, and Carl Lewis was eventually awarded a gold medal after the original winner failed a drug test. Another instance involved American shooter Jason Turner, who moved up to third place in the 10-meter air pistol competition after the original bronze medalist tested positive for a banned substance. These cases highlight the complexities and controversies surrounding Olympic medal disqualifications, often related to issues of fair competition and drug use.
