The NRL has moved to outlaw shoulder charges in tackles where more than one defender is involved.
The proposed rule change will ban the use of the shoulder in any exchange other than situations where there is a one-on-one collision.
The move comes following the public outcry over Riley Brown's late hit on Souths halfback Craig Wing on Friday night, which ruled Wing out for up to three months after undergoing shoulder surgery.
Sydney Roosters hooker Brown was found to have no case to answer by the NRL match review committee.
The NRL announced there would be close scrutiny of similar tackles in coming weeks with a view to recommending a rule change if it is deemed necessary.
"We have already made changes to our own judiciary guidelines to ensure that shoulder charges can be treated as high tackles where necessary and it is an area of the rules we watch closely," NRL chief operating officer Graham Annesley said.
"Certainly if we see any trend developing that is against the interests of the game we will act on that trend."
