Tobi Amusan, the Nigerian 100m hurdles world record holder, has pledged to “fight” after being charged with failing three drug tests.

If the Athletics Integrity Unit (AIU) maintains the accusation, the 26-year-old would miss the World Athletics Championships in Budapest next month.

The two-time Commonwealth Games gold medalist denies using performance-enhancing drugs.

“I am a clean athlete,” said Amusan on Instagram.

“I am tested by the AIU on a regular (maybe more frequent) basis.

“I am confident that this will be resolved in my favor and that I will compete in the world championships in August.”

At the World Championships in Eugene, Oregon in July 2022, Amusan set a new world record in the 100m hurdles, crossing the line in 12.12 seconds.

Athletics has a ‘three strikes’ rule, and it is reported that Amusan failed three doping tests in the span of a year.

According to World Athletics’ anti-doping rules, any athlete who fails to notify their whereabouts for a doping test three times in a 12-month period is barred from competing for two years, subject to a reduction to a minimum of one year depending on the degree of fault.

“I intend to fight these charges, and my case will be decided by a tribunal of three referees before the World Championships start next month,” Amusan said.

On Sunday, Amusan won the Diamond League meet in Silesia, her second triumph in the series this season after a victory in Stockholm.

“[Tobi Amusan] has today been charged and provisionally suspended for 3 Whereabouts Failures,” the AIU tweeted.

“The charge will be heard by the Disciplinary Tribunal and determined before the World Athletics Championships.”

The World Athletics Championships will be held in Budapest from August 19 to 27.
