Lowering the Tackle Height Cuts Concussions in Adults - What It Means for School Rugby
New evidence confirms that lowering the legal tackle height in adult rugby significantly reduces concussion rates. Here is what school rugby coordinators need to understand about the emerging data and how it applies to the community game.
Lowering the Tackle Height Cuts Concussions in Adults - What It Means for School Rugby
Key takeaways
- New analysis confirms that lowering the legal tackle height in adult rugby has meaningfully reduced concussion and injury rates in community and elite settings.
- The evidence draws primarily on adult cohorts, so direct application to under-18s requires careful interpretation.
- World Rugby recommended in late 2025 that a lower tackle height be written into community game law; some unions are already implementing it.
- The rule change affects coaching priorities: technique, not just protocol, is now a concussion-management tool.
- School rugby coordinators should review their coaching approach now, not wait for their NGB to mandate it.
A game-changing piece of analysis from RTÉ and reported widely this week makes the case more clearly than ever: lowering the legal tackle height in adult rugby has reduced both concussion rates and overall injuries. The data is significant. And while most of the evidence comes from adult competition, the implications for school rugby are real and immediate.
This article explains what the evidence shows, what it does not show, and what UK school rugby coordinators should be doing right now to incorporate lower tackle height into their concussion management approach.
What does the evidence on tackle height actually show?
The most substantive trial data comes from the IRFU's two-season tackle behaviour trial, the results of which were published in November 2025. Over two seasons, teams operating under a lowered tackle height law saw a measurable reduction in concussion incidence and other contact injuries. Critically, the reduction was not marginal. Concussion rates fell, and the game remained recognisably rugby.
This built on earlier research commissioned by World Rugby, which found that tackles above the shoulder line account for a disproportionate share of concussion events. The logic is straightforward: a tackle that makes contact with the head or neck region carries far more concussion risk than one absorbed through the trunk. Lowering the legal height removes the highest-risk contact zone from routine play.
In December 2025, World Rugby formally recommended that a lower tackle height be written into community game law. Several unions are now in the process of incorporating it, including the RFU for adult community rugby.
Does this evidence apply to school rugby?
Carefully, yes. The trial populations were adults, not schoolchildren. That is a meaningful distinction: developing bodies and brains do not absorb and recover from contact in the same way as adult ones. You cannot simply transplant adult findings to a U16 fixture.
That said, the underlying mechanism is the same regardless of age. A tackle that avoids the head and neck reduces the energy transfer to the brain. The CISG 6th Consensus Statement (2023) is explicit that contact with the head is the primary mechanism of concussion in collision sports. Nothing about that biomechanics is age-specific.
The UK Concussion Guidelines for Grassroots Sport (Sport and Recreation Alliance, November 2024 update) do not yet specify a legal tackle height for youth rugby, because the NGB-level law changes are still rolling through. But the guidelines are explicit that reducing head contact is a primary prevention priority. Schools that adopt lower tackle height coaching are acting consistently with those principles, even ahead of formal law change.
The Luca Safe Concussion Framework positions prevention as the first layer of a complete concussion management approach, not a substitute for identification and return-to-play protocols but a complement to them.
What changes for school rugby coordinators right now?
Three things deserve immediate attention.
1. Update your coaching emphasis, not just your policy documents.
A tackle height rule change only works if players are coached to execute it. The technique shift from a shoulder-level to a sub-sternum tackle is not trivial. Players who have learned to tackle at hip-or-above need progressive reteaching. World Rugby's Tackle Ready programme provides a structured coaching framework for exactly this transition. If your school is not using it, now is the time.
2. Distinguish between what is law now and what is coming.
As of June 2026, the lower tackle height is a recommendation from World Rugby for community game law adoption. The RFU's timeline for incorporating it into binding regulations for school fixtures is not yet finalised. That means coordinators should not present it to players and parents as a current legal requirement for school matches, but should be coaching it as best practice and preparing for mandatory adoption.
3. Document your coaching changes.
If a parent or insurer asks what your school has done in response to evolving evidence on tackle technique, you want a paper trail. Record the dates you updated your coaching sessions, which staff attended CPD on the lower tackle, and when the technique change was briefed to players. This is not bureaucracy for its own sake; it is the kind of documented evolution of practice that demonstrates genuine duty of care under the Health and Safety at Work etc. Act 1974.
What does the lower tackle height rule NOT fix?
It is important not to overstate the finding. Lower tackle height reduces concussion incidence; it does not eliminate it. Concussions still occur in lower-body tackles through unintended head contact, awkward falls, and incidental collisions. The November 2024 UK Grassroots Concussion Guidelines still apply in full: if there is any suspicion of concussion, the player must leave the pitch and not return. A 21-day minimum stand-down for confirmed concussion in under-18s remains in force regardless of how the tackle was made.
The "if in doubt, sit them out" principle is not relaxed because the tackle laws are tightening. Rule changes are a population-level intervention. Individual incidents still require individual management.
What about the elite game - does any of this trickle down?
It is worth being precise here. The RFU HEADCASE programme and World Rugby's elite protocols operate differently from the community game frameworks. The Head Injury Assessment (HIA) protocol used at Premiership and international level involves pitchside medical staff, structured off-field assessments, and multi-day stand-down decisions made by team doctors. None of that infrastructure exists at school fixture level.
The lower tackle height evidence comes largely from community and semi-professional cohorts, not elite. That is actually good news for school rugby: the data is more applicable to non-elite play than if it had come exclusively from Test-match research.
Practical steps for school rugby coordinators
Here is a concrete checklist for the next few weeks.
- Review your current tackle coaching sessions. Are players being coached to tackle below the sternum? If not, build in a dedicated session before next term.
- Assign a member of staff to track RFU guidance updates. The law change is coming; you want to know when it becomes binding for your fixtures.
- Record your CPD activity. Any coaching update, staff briefing, or technique session should be logged with a date.
- Do not reduce your concussion identification or return-to-play rigour. Lower tackle height is prevention, not replacement. The full concussion pathway - recognition, stand-down, graduated return - still applies to every incident.
- Brief parents. A short note at the start of next season explaining that the school is proactively adopting lower tackle height coaching is good communication and good risk management.
