Luke Campbell continued his whirlwind start to his professional career with a first-round knockout win over Neil Hepper.
Campbell marked his debut by defeating Andy Harris inside a round in July and the lightweight halted Hepper in just one minute and 59 seconds at London's 02 Arena.
The Olympic gold medallist looked a class above his opponent from the start and unleashed crisp combinations in the opening minute.
Hepper's head was rocked back by straight left hands before a looping right sent him toppling to the floor.
The Darlington fighter appeared unhurt, but he was soon wincing in agony after Campbell unleashed a spiteful right hand to his ribs.
Hepper crumpled to the canvas and could not beat the count as Campbell racked up another swift win.
The Yorkshireman was delighted with his explosive performance in front of a packed out venue.
"I'm switched on, I train hard and come fight night I'm ready and prepared. I just want to excite the fans," he said.
