Rampage Jackson apologized on social media on behalf of his son and said the incident was a miscommunication. He said his son was unexpectedly hit in the head moments before Smith's match and was told that he could get his "payback" in the ring as part of the show.

Raja Jackson, the son of MMA legend Rampage Jackson, is being investigated by the Los Angeles Police Department after a brutal assault at a wrestling event.

The footage showed Mr. Jackson, son of the former UFC champion Quinton Jackson, punching the wrestler Stuart Smith at least 20 times.
