Dillian Whyte is being accused of failing a drugs test, prior to his heavyweight fight against Oscar Rivas at the O2 Arena on Saturday night.
President of the WBC, Mauricio Sulaiman, who had sanctioned the bout as a final eliminator for Deontay Wilder’s world title confirmed to Sportsmail on Wednesday night: “We are hearing the same”.
It is alleged Whyte had tested positive for ‘at least two banned substances’.
The tests are believed to have been administered by the British agency UKAD on July 17.
It is understood that the results were reported to Whyte’s Matchroom promoters and the British Boxing Board of Control, with the latter allowing the fight to go ahead according to legal protocol pending B sample tests and appeals.
If Whyte’s B sample is negative, then he would be cleared of any wrongdoing.
But if the results are ratified, it will probably spell the end of his world title ambitions.
Promoter Eddie Hearn, took to Twitter in the early hours of Thursday to write: “Further to reports I can confirm that both Dillian Whyte and Oscar Rivas were subject to extensive VADA and UKAD testing for their bout. Both fighters were cleared to fight by both bodies and the BBBofC [British Boxing Board of Control].”
