Stuart Smith, the professional wrestler who goes by the ring name "Syko Stu," is "stable but in critical care" after allegedly being brutally beaten by mixed martial artist Raja Jackson at a Knokx Pro Wrestling event on Saturday.

It was supposed to be a scripted event, but police are now investigating what looked to be an attack by Raja Jackson against a wrestler. Jackson is the son of former UFC light heavyweight champion Quinton "Rampage" Jackson.

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.
