Conor Benn's failed drug test has thrown his fight with Chris Eubank Jr into serious doubt.
Benn returned an adverse finding when he was tested at the end of August but the result has only been made public today. The British Boxing Board of Control has said the fight cannot go ahead but both Benn and Eubank Jr insist it can, and will.
The substance Benn tested positive for is clomifene, which is a female fertility drug which can also boost testosterone levels in men. But Eubank Jr's promoter Kalle Sauerland insisted he is confident Benn has not gained an advantage.
