Tries in rugby union can no longer be scored by grounding the ball against the post protector.
The law change, which comes to effect immediately, was approved by the global governing council.
The international body released a statement after its Council Meeting saying that safety concerns were part of the reason for the decision.
With defenders required to stay in the in-goal and post protectors being larger for player welfare, World Rugby deemed it was too difficult for teams to defend against this kind of scoring.
