Chris Eubank Jr. won an instant classic over Conor Benn on Saturday in London, with father Chris Eubank Sr. unexpectedly joining his corner.

Eubank Jr, with Sr in his corner in a late twist, won a scintillating duel with Benn – 30 years after their fathers settled their own bitter grudge

Despite the size difference, Benn came out fearlessly in the opening rounds, using angles and footwork to avoid Eubank's jab and unloading with winging power shots that connected behind a quick jab. In the third round, Benn landed a heavy left that left Eubank with no option but to clinch and recover.
