Gane came out in the second and never let Pereira settle, his pressure relentless and his punch volume overwhelming. The killer blow came in the form of a brutal right jab that connected flush with Pereira’s chin. After a further barrage, referee Herb Dean had seen enough.It was a performance that denied Pereira an unprecedented third divisional title and sets up a rematch with Tom Aspinall for the undisputed heavyweight title. For Gane, long considered one of the division’s nearly-men, this changes everything.The night opened with a brilliant back-and-forth contest between Diego Lopes and Garcia, which swung decisively in the closing stages of round two when Lopes caught his opponent with a brilliant left hook that sent him crashing to the canvas.

Chandler was given no room to breathe and no route back into the fight.Bo Nickal was similarly dominant over Kyle Daukaus, controlling the bout on the ground before finishing with a knockout that underlined just how far he has come.
