Johnny Walker upset the odds today, scoring an upset knockout victory over China's own Mingyang Zhang in their UFC Shanghai main event.

‘Mountain Tiger’ Zhang Mingyang introduced himself to the American fans in April when he left former title challenger Anthony Smith in a pool of his own blood for his retirement fight. This was Mingyang’s U.S. debut and 19th career finish.

Zhang faces Johnny Walker in the UFC Shanghai headliner in a pivotal 205-pound clash. Around five weeks later, Magomed Ankalaev defends his title against Alex Pereira in a rematch to headline UFC 320 on Oct. 4 in Las Vegas.
