In a revision of the 'crouch, touch, set' engagement sequence currently being trialled, props will be expected to bind using their outside arm after the referee has called 'bind'. The front rows will maintain the bind until the referee calls 'set'. At that point, the two packs will engage.
The IRB Council approved the law trial in May, alongside a suite of five other aspects of law, on player welfare enhancement grounds as the revised sequence has the potential to reduce forces on engagement at the elite level by 25%, therefore promoting long-term benefits.
Addressing the scrum collapse issues that have been prevalent recently in elite tugby is not the driver of this change.
However, it is possible that the new 'crouch, bind, set' sequence, coupled with strict application of existing law by referees and universal positive attitude buy-in, could lead to a more stable platform and therefore fewer collapses and resets.
"Fundamental to this process will be buy-in from all to ensure a positive approach to the scrum and to tackle the issues that are prevalent at the elite level of the game.
"We anticipate an element of time for all to get comfortable with the new process, but if we can ensure a stable platform by working together, then the product will be better for all.
"The feedback that we have been getting from coaches and players around the world is that this is a positive change that enhances player welfare and scrum stability.
"The referee forum was incredibly positive and highly constructive and there is a commitment to ensure strict policing of the scrum feed."
