Conor Benn has failed a drug test ahead of his bout against Chris Eubank Jr but the bout will still go ahead.
The two will meet on Saturday night, 30 years after their fathers met in the ring for the second time.
But the bout has been marred by a failed drugs test with Benn testing positive for clomifene, a substance which is found in medication to treat infertility in women which can also boost testosterone in men.
