Dong Hyun Kim entered the Octagon for UFC Fight Night 29 a +245 underdog.

Those who gave Kim, mainly known for his judo acumen, any chance against Erick Silva mostly thought he could defeat the Brazilian by grinding out a slow-paced decision victory.

Few thought he’d be more explosive than the explosive Silva — noted for his flying knees and dynamic striking, and fighting in front of his home country’s typically rabid fans.

Yet, that’s just what happened. Kim, of Suwon, South Korea, recovered from some strong striking from Silva to score a huge right hand and knock the prospect out cold.

Kim struggled to get his takedowns and was out-landed early. He was able to maneuver to mount after Silva stumbled in the first. Silva would move to half guard and stay out of trouble however, and take the advantage in the second stanza with knees and elbows.

But the counter punch landed — and landed hard. Silva was knocked out cold with a big right as he tried a right hand of his own. Kim would then pounce on Silva with a hammer-fist, where referee Mario Yamasaki called a halt to the bout at 3:01 of round two.

The victory improves Kim’s record to 18-2 with one draw and one no-contest, which represented his third straight UFC victory. Silva drops to 15-4-1.
