Tensions boil over in the dying minutes of the match, resulting in David Klemmer being sent off.
The Knights enforcer got in a heated push-and-shove with Rabbitohs forward Keaon Koloamatangi, sparking an all-in scuffle.
The former Bulldog then dished out some dirty moves on Daniel Suluka-Fifita, digging in his elbow and forearm as he tackled the new Rabbitoh.
That ignited another all-in melee, before the referee called Klemmer to his attention and marched him from the field.
Latrell Mitchell then potted over a penalty goal to push South Sydney’s lead out to 40-28.
