Conor Benn will be reinstated to the WBC rankings after the organisation accepted his explanation that "highly-elevated" egg consumption could have been behind his failed drugs test.
The Briton was due to fight Chris Eurbank Jr in a high-profile contest last October, only for the bout to be pulled at short notice after he tested positive for the banned substance clomiphene.
A fight between the two was prohibited by the British Boxing Board of Control and eventually cancelled by promoters, with Benn subsequently struck from the WBC rankings.
But following an appeal, the WBC confirmed he would be reinstated on Wednesday after they did not find enough data to further support his suspension.
"The WBC found that there was no conclusive evidence that Mr. Benn engaged in intentional or knowing ingestion of clomiphene," said an official statement.
"[In addition,] there were no failures in the procedures related to sample collection, sample analysis, or violations of Mr. Benn’s B Sample rights that would justify questioning or invalidating the adverse finding.
"[Furthermore,] Mr. Benn’s documented and highly-elevated consumption of eggs during the times relevant to the sample collection, raised a reasonable explanation for the adverse finding."

Though Benn will return to the WBC rankings, he remains under investigation by the BBFoC and UK Anti-Doping (UKAD) and therefore is not licensed to box in the UK while those processes are ongoing.
However, he could now seek another country and a different jurisdiction in which to fight if he so chooses.
Eubank Jr suffered a third career loss last month in Manchester against Liam Smith, following the cancellation of his match with Benn.
