Conor Benn has failed a drug test ahead of his fight with Chris Eubank Jr - but the bout will go ahead.
Benn and Eubank are due to settle their family feud in London on Saturday night, 30 years after their legendary fathers met for the second time. But Benn, who is the underdog going into the bout, tested positive for clomifene, a substance found in medication to treat infertility in women but which can also boost testosterone production in men.
The test took place in August and Benn has since tested negative. A statement from promoters Matchroom read: "We have been made aware that a random anti-doping test for Conor Benn conducted by the Voluntary Anti-Doping Association returned an adverse analytical finding for trace amounts of a fertility drug. The B sample has yet to be tested, meaning that no rule violation has been confirmed.
