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?

Charles Johnson (18-7 MMA, 7-5 UFC) had a rough first round against the unbeaten Lone'er Kavanagh (9-1 MMA, 2-1 UFC). But late in the second round, while he was backing up from a Johnson attack, Kavanagh dropped his hands and Johnson drilled him on the button to put his lights out for the first loss of his career.
