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.

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.

With his brother Valter Walker in the corner in Shanghai, Johnny admitted he was “emotional” after his first three-fight winless run in the promotion. Training at Xtreme Couture in Las Vegas gave him confidence, but Walker felt he couldn’t perform at his best after a 14-month layoff.
