A grown-ass man was arrested Saturday after he attacked his son's high school wrestling opponent during a match ... and footage of the incident is INSANE.
The violence all went down during an event between Southeast Guilford H.S. and Hickory Ridge H.S. in Kannapolis, N.C. ... when a dad was so upset with the way his son's match was going, he bum-rushed the mat.
You can see in video of the incident ... the man charges his son's 17-year-old opponent, hitting him square in the back and knocking him to the floor. It looked like a Goldberg spear straight out of WWE.
