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.

Anthony Smith, the UFC light heavyweight veteran known as “Lionheart,” officially retired from mixed martial arts after a first-round TKO loss to Zhang Mingyang in the co-main event of UFC Fight Night Kansas City on April 26 2025.
