Welsh Rugby Union chiefs have reportedly vetoed controversial new proposals over red cards planned to be rolled out at this month's World Cup in Japan.
World Rugby held a conference call with leading figures across the game where plans to dilute red cards were seriously discussed.
Some of the game's decision-makers weighed up allowing a player sent-off - to be replaced by a substitute 15 minutes later.
That radical alteration would have left teams receiving red cards playing with 14 men for just five minutes longer than a yellow card, then being restored to a full complement.
But the Press Association reports leading figures in Wales, England, Ireland and Scotland have rejected out of hand suggestions to alter the punishment meted out for red cards in time for the World Cup.
But World Rugby will press ahead in Japan with their new procedure where the Television Match Official must now be consulted over all potential red-card decisions.
World Rugby confirmed that protocol amendment on August 30, which will now be in effect for the World Cup.
A number of top figures in the game have raised concerns over the interpretation of punishments for high tackles, with some worried any increase in red cards could damage the World Cup.
England boss Eddie Jones warned last month that the World Cup could be "destroyed" by inconsistent refereeing.
World Rugby issued new high tackle punishment decision-making framework for referees back in May, designed as another boost to player welfare and to simplify the process of disciplining foul play.
"World Rugby is committed to player safety and we collaborate with coaches, players and match officials on all player welfare matters, including the implementation of the high tackle sanction framework, which has been implemented after extensive trials demonstrating concussion reduction benefits," said a World Rugby spokesman.
"The inclusion of the TMO to aid referee decision-making in the implementation of framework for occasions of dangerous foul play is a common-sense addition, enabling the match official team to make full use of the advanced Hawkeye technology available at Rugby World Cup to further support clear and consistent decision making in this important area of the game."
