re: Where do I find the fricking rules on goalie protection

High school mean the ball was already kicked and the play was already 40 yards away when this little bitch from behind ran up and tackled him. I have no clue why as there was really no advantage in it but it was simply chicken shite. He was still in the box and threw his hands up and yelled what the hell ref? The side judge threw his hands up as in a foul they stopped play then they talked and waived it off. Crowd went nuts.

I know u are not allowed to grab a goalie in the box.
