Conor Benn apparently has not been as forthcoming to one investigation as he has been to another regarding his two failed drug tests.

In December, the embattled British welterweight had his attorneys submit a 270-page report to the World Boxing Council, in an apparent bid to get the sanctioning body to reinstate him into its welterweight rankings. The body, which is conducting its own investigation, had removed Benn from its standings after he was revealed to have tested positive for the banned performance-enhancing drug clomifene in October, a few days before his scheduled 157-pound clash with Chris Eubank Jr. It was subsequently discovered that Benn had failed a separate test for the same substance earlier in the summer. The Voluntary Anti-Doping Association administered both tests.

Benn is also under investigation by UK Anti-Doping and the British Boxing Board of Control; their findings could determine whether or not Benn faces a ban in his country.

According to a report by the Daily Mail, a British newspaper, Benn has not submitted the same 270-page report to UKAD, saying that a "lack of cooperation" from Benn has evidently led to a snag in UKAD's investigation.   

The Board’s head, Robert Smith, confirmed to the Mail that Benn’s legal team had not presented them with the document. UKAD, as a policy, does "not comment publicly on any case that may or may not be ongoing."

Benn has repeatedly mentioned the WBC investigation in his recent social media posts, urging the body to speed up their investigation, but he has, as the Mail noted, been far more tight-lipped when it comes to the UKAD inquiry.

Benn has made it clear the report he turned into the WBC will vindicate him, stating recently that he believes “science” will back him up. Benn’s line of argument may be based on a contamination angle. The Mail reported in October that Benn had indicated his vast intake of chicken eggs may have led to the “trace” presence of clomifene in his body.  

“Been through hell and back,” Benn posted on his Instagram account recently. “Thank God for science. The evidence doesn’t lie. No holes in the truth.”

Benn’s promoter Eddie Hearn has repeatedly insisted that Benn is allowed to fight and that he will be back in the ring in the next six months.
