Chris Eubank Jr has failed to make the weight ahead of Saturday night's main event clash with Conor Benn.
Eubank weighed in at 160.2lbs on his first attempt, before following up at 160.05lbs on his second and last attempt.
He will reportedly face a fine of $500,000 (£375,500) and cannot exceed 170lbs at the same-day weigh-in on Saturday otherwise he will face another penalty.
Conor Benn weighed in at 156.4lbs earlier today, with Eubank Jr arriving over an hour late.
