Chris Eubank Jr will fight fellow Briton Conor Benn in a rematch in London on 20 September.
Eubank beat Benn by unanimous decision after a thrilling bout at the Tottenham Hotspur Stadium in April, though the venue for their second meeting has yet to be confirmed.
The fight took place 35 years after their legendary fathers, Chris Eubank Sr and Nigel Benn, first fought and garnered huge attention despite no title being on the line.
All three judges scored it 116-112 in favour of Eubank, who extended his record to 35 wins in 38 fights.
Eubank arrived at the stadium with his father by his side, despite the pair having apparently been estranged for a number of years.
