The RFL will conduct a full investigation into the ugly scenes yesterday at the end of the Huddersfield against Salford match.
Salford supporters and players were involved in heated exchanges in the stands after full-time.
Rugby Football League chief executive Nigel Wood said: “We will conduct a full investigation into the events that took place in the away section of the crowd at the game between Huddersfield and Salford.
“We do not condone violence of any kind and will ensure that anyone found to have acted improperly is dealt with accordingly.”
Justin Carney and Junior Sa’u went into the stands to protect their families.
Salford head coach Ian Watson said the children of Carney and team conditioner Greg Brown were “a little bit shaken” by the incident.
“They’re all OK, but they shouldn’t be scenes you see at rugby,” he said.
“It should be a good game and family sport to come to. People that are causing problems and fighting don’t deserve to be involved.”
It has been reported that a flare was thrown from the Salford end and a supporter escorted out, just before the trouble began.
