Namibian sprinters Christine Mboma and Beatrice Masilingi have been ruled ineligible for the Tokyo Olympics by the World Athletics organization.
Per an official statement from the Namibian Olympic Committee, Mboma and Masilingi have been deemed ineligible to compete because they have naturally high testosterone levels that are above the threshold allowed by World Athletics, the international governing body for track and field.
The International Amateur Athletic Federation adopted a new eligibility policy in 2019 for the 400 meters, 400-meter hurdles, 800 meters, 1500 meters, one-mile races and all other events between 400 meters and one mile.
