World Rugby chief executive Brett Gosper has called for referees to brandish more red and yellow cards in an effort to eradicate the dangerous tackles he believes are blighting the game.
“The cards are there to change behaviour,” Gosper told the Daily Telegraph. “They only continue to be a problem if behaviour does not change.
“The only way you can get player behaviour to change is to sanction with red cards and actually, we have probably not seen enough of it.
“I would say in many ways we have probably not been hard enough. There have probably not been as many yellow cards as we would like, and maybe not even as many red cards as we would like.
“We have not had the behaviour change that we are seeking yet, so we have to continue in that vein.”
