The fight between Conor Benn and Chris Eubank Jr, due to take place in London on Saturday, has been postponed.
It comes after Benn, 26, returned what promoters said was an "adverse analytical finding for trace amounts of a fertility drug".
The British Boxing Board of Control had said the bout was "prohibited and not in the interests of boxing".
Promoter Matchroom confirmed on Thursday that the fight had been postponed.
