Syko Stu

Stuart Smith (born November 16, 1980), better known as Syko Stu, is an American retired professional wrestler and military veteran best known for his stage presence and military service.

Smith joined KnokX Pro after a Honorable Discharge from the military in 2009. According to Smith, this was to help deal with the PTSD he suffered after serving.

Raja Jackson incident In August 2025, Smith was involved in an incident with Raja Jackson, son of Quinton Jackson. Raja knocked Smith unconscious during an incident where Raja slammed Smith and proceeded to punch him a total of 22 times, 18 of which were to his head, at a KnokX Pro Wrestling event. Smith was sent to the hospital and was later reported to be in “stable but critical” condition, reportedly awake but missing teeth, and suffered broken bones in his face. Quinton Jackson said he was "deeply concerned" and "very upset that any of this happened" and described it as a "work gone wrong". On August 25, the KnokX Pro Academy was removed from the list of WWE ID-affiliated schools featured on the WWE Recruit site. In addition, Raja was banned from Kick.

On September 2, Smith was released from the hospital and returned to his home to recover.

In May 2026, Raja Jackson reached a plea deal with an "anticipated sentence" of 90 days in jail, two years of probation and paying more than $81,700 in restitution. Smith released a statement on May 10 that he has "no grudges" against Jackson.
