Joo Sang Yoo debuts with 28-second faceplant KO over Jeka Saragih on the UFC 316 prelims

'Zombie Jr.' Joo Sang Yoo debuted as one of the biggest favorites on the card, as he took on the dangerous Jeka Saragih. Yoo hailed from ZFN, bringing an undefeated 7-0 record into the UFC Octagon, with four first-round knockouts.

Saragih came out of the gates with his patented aggression, but it would be his undoing. Yoo backpedaled and threw a fade-out left hook that caught Saragih perfectly on the chin.

Fist met momentum, spinning Saragih's head on its axle, before the Indonesian slugger toppled like a tree to the ground. His face took the brunt of the impact before Yoo clubbed him with a follow-up shot to secure the win.
