Team USA sprinter Christian Coleman is reportedly facing a potential ban after missing multiple drug tests.
According to ESPN, Coleman failed to partake in three separate drug tests over a one-year period, which can be treated as a positive test under the U.S. Anti-Doping Agency's policy.
Coleman won silver in the 100-meter dash at the 2017 World Athletics Championships, and he is considered a gold medal-threat at the 2019 World Championships and 2020 Summer Olympics in Tokyo should he be allowed to compete.
