I saw the incident in the link. I think the refs got it right.
"SOUTH Sydney prop George Burgess was sent to the sin bin for an ugly incident in Saturday’s clash with Newcastle.
But he should’ve been sent off for the remainder of the game, according to former NRL player and
Fox Sports commentator Michael Ennis.
Burgess lost the ball in a big hit from Knights lock Mitch Barnett in the 23rd minute which caused the Rabbitohs’ wrecking ball to lash out, first with his elbow, then fists.
“Looking at the replay, it should’ve been (a send off),” Ennis told
Super Saturday."
