Professional wrestler Stuart Smith — also known as "Syko Stu" — is in critical condition after repeated, vicious punches by Raja Jackson during a Knokx Pro Wrestling match that went wrong, leading to a police investigation.

Syko Stu, the independent wrestler who was beaten unconscious during a disturbing attack from the son of a former UFC star, is in stable condition but remains in critical care, according to an update his brother Andrew provided.

The shocking attack from Rampage Jackson's son Raja left a professional wrestler in hospital with facial injuries.
