Dillian Whyte has been cleared by UK Anti-Doping following an adverse finding in a drug test before his victory over Oscar Rivas in July.
The heavyweight contender was informed of the result just days before his final eliminator for the world title held by Deontay Wilder.
He was cleared to fight on the morning of the contest but news of the finding was not made public until the following week.
Whyte was never banned and his points win over Rivas stood, but a cloud of controversy remained, particularly with the Londoner due to return to the ring this weekend against Mariusz Wach.
But in a statement issued on Friday night, UKAD confirmed there was nothing in Whyte’s urine test which suggested he had taken banned streroids.
They also noted that Whyte passed a drug test three days before the June 20 sample which raised the red flag.
Several other tests also came back negative during the month preceding the fight.
In response to the outcome, Whyte issued a thinly-veiled message on Twitter.
He said: “For those who believed in me I won’t forget you . To those who didn’t, I won’t forgive you and I know who you are.”
The 31-year-old’s victory over Rivas earned him the interim heavyweight world title and should have guaranteed him a shot at the winner of Wilder’s rematch against Tyson Fury which is scheduled for February 22.
But the WBC pushed Whyte’s shot back until 2021, regardless of the outcome of UKAD’s investigation.
The statement from UKAD read: “Having rigorously scrutinised and investigated the detailed factual and scientific evidence provided by Mr Whyte, UKAD is satisfied that the presence of the very low amounts of metabolites in his June 20, 2019 sample was not caused by any fault, negligence or wrongdoing on Mr Whyte’s part and, given the circumstances, could not have affected the fight between Mr Whyte and Mr Rivas on July 20, 2019.
“Indeed, prior to that fight, an independent tribunal considered a number of the above factors before deciding to permit Mr Whyte to participate. Following that preliminary ruling, UKAD continued its investigation and Mr Whyte provided further evidence in his defence, which has culminated in UKAD’s decision to withdraw the charge.
“Mr Whyte acknowledges that, based on the test results reported to UKAD relating to his June 20, 2019 sample, UKAD acted in accordance with the UK Anti-Doping Rules by issuing the initial charge and in the conduct of its investigation.
“Pursuant to the terms of the UK National Anti-Doping Policy, UKAD must always act in the interests of justice and not solely for the purpose of obtaining determinations adverse to athletes.
“In the present case, UKAD considers that means that the appropriate course of action is for the charge against Mr Whyte to be withdrawn and does so in accordance with the relevant anti-doping rules.
“The British Boxing Board of Control, having delegated responsibility for anti-doping matters to UKAD, has been informed of the resolution of these proceedings against Mr Whyte.”
