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.

The UFC’s return to Shanghai is officially in the books, and the event ended with Johnny Walker pulling off a big upset in the main event, and a former bantamweight champion making a case for a title shot in a second division. Where do both fighters go from their big wins?

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.
