Trying to brace himself from a slam by Olympic wrestler Fredy Serrano, Yao Zhikui suffered an arm injury that cost him the fight.
Serrano defeated Zhikui via TKO at 0:44 of round one.
Serrano vs. Zhikui served as part of the preliminary card of Saturday morning's UFC Fight Night 79 in Seoul, South Korea.
Just like that! @FredySerrano125 gets the W tonight at #UFCSeoul! https://t.co/sKrPiSKaVA
