For all of the hype surrounding first-round knockout artist and Chinese light heavyweight prospect Zhang Mingyang, all it took was a second-round rally from the always unpredictable Johnny Walker to provide a heat check during Saturday's UFC Fight Night main event in Shanghai.

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.

The light heavyweight bout was scheduled for five rounds, but they all were not needed. Walker (21-9 MMA, 7-6 UFC) finished Zhang (19-6 MMA, 3-0 UFC) with a violent and diversified beatdown barrage for the stoppage at 2:37 of Round 2.
