But based on his performance on Saturday night at UFC 170, he's not likely to stick to the online prelims for long.
"What you saw tonight was the real Erik Koch," he said.
Koch gave an indication what was to come when he dropped a charging Oliveira with a right hand. Oliveira got right back up, but soon thereafter was dropped by a straight left. A ground-and-pound assault caused referee Yves Levigne to wave off the fight.
"I'm not a boy, I'm a man, that was too much weight to cut," said Koch (16-6), who had his ninth career finish. "This is what the ‘New Breed' is all about."
Oliveira (15-7) lost for the fourth time in his past five fights.
