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

Veteran light heavyweight contender Johnny Walker secured his first UFC victory in more than two years with a hard-fought comeback win on Saturday at UFC Fight Night 257 in Shanghai, China.

Zhang Mingyang got what they call “fraud checked” earlier today (Sat., Aug. 23, 2025) at UFC Shanghai LIVE on ESPN+ from inside the Shanghai Indoor Stadium in Shanghai, China, suffering an upset TKO (leg kicks and punches) to light heavyweight veteran Johnny Walker in the main event.
