Blues get first look at tackle laws
Leinster will be the first Irish team subjected to World Rugby's updated sterner laws regarding illegal high tackles when they take on Zebre in the Pro12 at the RDS on Friday night
As of yesterday, World Rugby's new directives on what constitutes a dangerously high tackle - intentional or accidental - came into effect.
In a move the governing body described as a "new tougher approach," referees now have the ability to issue harsher sanctions for reckless and inadvertent head contact.
The new rules see punishable tackles divided into two categories, reckless and accidental.
A tackle will be deemed reckless if the tackler knew, or should have known, that there was a risk of making contact with an opponent's head but did it anyway.
It also applies if the tackle starts below the line of the shoulders, and to grabbing, rolling or twisting around the head and neck area - which frequently occurs in the breakdown area.
The minimum sanction for such offences is a yellow card, while the maximum will be a red card.
Furthermore, the minimum of a penalty will be awarded should a player make accidental contact with an opponent's head, including when the ball-carrier slips into the tackle.
