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.

In Saturday's UFC Fight Night 257 co-main event, Sterling (20-5 MMA, 17-5 UFC) cruised to a unanimous decision (50-45, 50-45, 50-45) win over Ortega (16-5 MMA, 8-5 UFC) at Shanghai Indoor Stadium in Shanghai.

Johnny Walker ended a skid of two straight knockout losses by scoring a shocking knockout of his own in a comeback win against Chinese light heavyweight Zhang Mingyang in the main event of UFC Fight Night in Shanghai.
