The British Boxing Board of Control says it will not sanction Saturday's grudge showdown between Conor Benn vs Chris Eubank Jr.
The rivals are due to meet at the O2 Arena in London but the fight was plunged into doubt on Wednesday when it emerged Benn failed a drug test.
Both promoters insist the bout will take place but the BBBoC claims it told the promoters yesterday that they would not sanction the fight, reports the Mirror.
