Three UFC Kansas City fighters, including Anthony Smith, are out indefinitely after the Missouri commission has requested neurological clearance.

Playing the role of spoiler was Zhang Mingyang, who proved too much for Smith (37-22 MMA, 13-12 UFC) to handle. The light heavyweight fight served as the UFC on ESPN 66 co-main event at T-Mobile Center in Kansas City, Mo. Mingyang (19-6 MMA, 3-0 UFC) remained undefeated in the UFC by stopping Smith with heavy ground and pound at 4:03 of Round 1.

Zhang Mingyang comes out with a big victory in the co-main event of UFC Fight Night over Anthony Smith, who announced he would retire after the fight.
