This amendment to aid decision-making follows an initial review of progress since the framework's implementation in May 2019 by the international federation's executive committee with the objective of ensuring that the important player welfare initiative continues to optimise clear and consistent officiating.
The amendment will enable the match officials to have full use of the comprehensive Hawkeye technology that will operate at World Cup 2019 to support on-field decision making.
In a statement, World Rugby said: "The committee has given its full backing to the process, its implementation by the match officials and has endorsed the continued close collaboration and communication between coaches, players and match officials ahead of the World Cup.
"World Rugby is committed to reducing the risk of injury in the sport. The high tackle sanction framework was developed in collaboration with unions, coaches, players, referees and medics to drive consistency and simplicity to the process of identification and sanctioning of dangerous foul play that carries the greatest risk of head injury.
"It is intended to change player behaviour from positions of high risk to low risk, by the promotion of good technique.
"The amendment will further promote consistency and accuracy of decision-making, supporting referees in this critical player welfare and match-management area."
