Reigning world champion Tobi Amusan has yet to receive clearance to compete at this week’s World Athletics Championships in Budapest as she remains under provisional suspension, according to the sport’s governing body.

Amusan, the Nigerian 100m hurdles record holder, is currently subject to an Athletics Integrity Unit (AIU) review after accumulating three whereabouts failures. Despite being listed in preliminary entry lists, her participation hinges on the outcome of the AIU case.

“No decision has been made in this case yet. When a decision is made, it will be announced by the Athletics Integrity Unit,” World Athletics communications head Nicole Jeffery confirmed.

The Athletics Federation of Nigeria stated it awaits the AIU’s ruling, expected before the championships commence. Amusan made history last year, becoming Nigeria’s first ever gold medalist and world record holder.

The 26-year-old had started this season strongly, clocking a new personal best time in July. But her breakthrough 2022 campaign was halted by her provisional suspension for whereabouts violations just weeks later.

With the AIU yet to render judgement, uncertainty remains over whether Amusan will defend her 100m hurdles title in Budapest. Afn officials and Nigerian fans hope the review concludes in time to clear the nation’s top medal contender.
