Some other contenders still in the race are Olympic champion Jasmine Camacho-Quinn and USA’s Nia Ali.

Amusan’s participation at this year’s championship was in doubt until last Thursday, when she was cleared by the Athletics Integrity Unit.

The body lifted the suspension on her after a panel of the Disciplinary Tribunal, by majority decision, found her not guilty of an Anti-Doping Rule Violation of three whereabouts failures within a 12-month period.

The decision was a relief for Nigerians and she also expressed her eagerness to return to the track in Budapest.

“I am thrilled to put this behind me, and I look forward to defending my title at the World Championships. I generally have been and consistently will be an ally of clean sport,” her statement read in part.
