Chris Eubank Jr has been fined £100,000 for slapping Conor Benn with an egg during a chaotic media conference last month.
As the pair prepared for the obligatory face-off, Eubank produced an egg from his pocket and hit his British rival across the cheek with his left hand.
Benn, with his father Nigel next to him, lost control and both boxers were held back by security guards.
In a statement, the British Boxing Board of Control said Eubank, 35, was in breach of regulation 25 in relation to misconduct.
The incident happened in Manchester on 25 February as the pair promoted their fight at the Tottenham Hotspur Stadium next month.
A scheduled fight between the pair in October 2022 was called off when Benn failed a voluntary drugs test, prompting a two-year battle with anti-doping authorities, before his suspension was lifted in November.
Benn has always denied intentionally doping and both fighters are being tested by the Voluntary Anti-Doping Association (Vada) for the contest.
An independent report by the World Boxing Council (WBC) in February 2023 said the 28-year-old’s failed drugs test was not intentional and could have been caused by a “highly elevated consumption” of eggs.
“Apparently egg contamination was the reason for his two failed drugs tests. So I contaminated him with an egg,” Eubank posted on social media with a clip of the incident.
