Quinton Jackson and the promotion that held the show said the incident involving Raja Jackson and wrestler Stuart “Syko Stu” Smith appeared to be a case of a planned spot gone wrong.

Los Angeles police are investigating a case involving Raja Jackson, son of ex-UFC champ Quinton "Rampage" Jackson, who is shown on video punching an apparently unconscious pro wrestler at least 20 times in the head.

On Saturday, Raja Jackson — whose father is former UFC champion fighter Quinton "Rampage" Jackson — was set to fight Suart "Syko Stu" Smith, 47, during a KnokX Pro Wrestling event in Los Angeles, which was also being streamed on Kick.
