Britain’s Conor Benn said his team had proven his innocence and “the truth will come out soon” following his positive test for a banned substance.
The 26-year-old has tested positive for the female fertility drug clomiphene, but says ‘contamination’ is to blame.
“I’ve been through hardships before in my career, but nothing like it,” he said on social media.
“I believe that in life you go through all kinds of adversities, but what matters most is how you react.
“I stayed in the gym and continued to work extremely hard, staying positive. My team proved my innocence and the truth will come out soon.”
After Benn’s fight with Eubank Jr was called off, the British Boxing Board of Control said it had “voluntarily renounced” his boxing license.
However, his promoter Eddie Hearn said his the license had expired and that the charge of misconduct against him was “absurd”.
Benn was summoned to a hearing on October 21, when “allegations of misconduct” were brought against him.
He is being investigated by UK Anti-Doping and the WBC’s own boxing programme.
Benn and Eubank were due to meet on October 8 at a catchweight of 157 pounds, 30 years after their fathers Nigel Benn and Chris Eubank Sr fought.
“I’m grateful to my dad, who has been with me this whole time and I’m glad this nightmare is coming to an end for the sake of our combined sanity,” Benn added.
“We never thought we would experience something like this, but they say the hardest fight is life and the adversity it brings.
“I want to make up for lost time and not let another moment go to waste.”
Clomiphene can be used to increase testosterone levels in men and is banned in and out of competition by the World Anti-Doping Agency (WADA).
“We never cut corners or cheated in any way,” Benn said of his team.
“We believe in the work ethic, determination and pure heart to achieve what we set out to achieve.”
Benn, who expects to be back in the ring in 2023, added: “We keep pushing forward and will keep aiming for the end goal of being world champion – it’s a minor setback for a major comeback. “
