In an announcement on X, the platform previously known as Twitter, the Athletics Integrity Unit (AIU) confirmed that Amusan “did not commit an anti-doping rule violation.”

He said, “A panel of the Disciplinary Tribunal, by majority decision, has today found that Tobi Amusan has not committed an Anti-Doping Rule Violation (ADRV) of three Whereabouts Failures within 12 months.

“AIU Head Brett Clothier has indicated the Athletics Integrity Unit (AIU) is disappointed by this decision and will review the reasoning in detail before deciding whether to exercise its right of appeal to the Court of Arbitration for Sport (CAS) within the applicable deadline. The decision is currently confidential but will be published in due course.”

The AIU temporarily suspended Amusan after missing three drug tests, but the Nigerian decided to defend herself against the allegation.

With an outstanding performance last year, the 26-year-old made history in Oregon, USA.

In the semifinal, she established a new world record of 12.12 seconds, and in the final, she won the gold with a wind-assisted 12.06 (+2.5 m/s).

Following her successful defenses of her Nigeria, African Championships, African Games, Commonwealth Games, and Diamond League titles, Amusan has only yet to compete in the World Championships.

The dates for the 2023 World Athletics Championships are August 19–27.
