Johnny Walker admits Octagon rust slowed him early but he recovered to score a brutal second-round TKO over Zhang Mingyang at UFC Shanghai.

Mingyang Zhang vs. Johnny Walker squared off in a Light Heavyweight contest earlier tonight (Sat. Aug. 23, 2025) live on ESPN+ inside Shanghai Indoor Stadium in Shanghai, China. In a wild fight, Walker secured the knockout win.

With the victory, Walker snaps a three-fight winless streak (two losses and one no contest). The victory was his first since he beat Anthony Smith by unanimous decision in May 2023. In defeat, Zhang loses for the first time in the UFC after promotional victories over Brendson Ribeiro, Ozzy Diaz, and Anthony Smith.
