Nigerian 100m hurdles world record holder Tobi Amusan has been charged by the Athletics Integrity Unit (AIU) for missing three doping tests within a 12-month period .
The AIU is an independent body that manages all integrity issues in athletics, including doping and non-doping rule violations.
Amusan, however, disputes the charge and has vowed to fight it. She denies taking performance-enhancing substances and has stated that she is a clean athlete who is regularly tested by the AIU. Amusan intends to fight the charges and her case will be decided by a tribunal of three referees before the start of the World Championships next month.
Under the World Anti-Doping Agency (WADA) rules, athletes are required to provide their whereabouts information to anti-doping authorities so that they can be located for out-of-competition testing. If an athlete misses three tests within a 12-month period, it is considered a doping violation and can result in a ban from competition.
The Nigerian hurdler has been a dominant force in her event, setting a new world record of 12.42 seconds at the Diamond League meeting in Monaco earlier this year. She is also a two-time African champion and won a silver medal at the Commonwealth Games in 2018.
