Tackle Height Rule Change Cuts Adult Concussions - But Not in Schoolboys

Key takeaways

• A new study of community rugby found a sharp fall in concussions among adult players after the lower tackle height law was introduced.
• The same reduction was not seen in schoolboy rugby, where concussion rates remained unchanged.
• The findings suggest the law change alone is not sufficient to protect younger players, and that additional interventions are needed at school level.
• The study adds important nuance to the tackle height debate: what works for adult athletes may not translate directly to a school-age population.
• Schools should treat this as a prompt to review their concussion identification and management frameworks, not to assume rule changes have solved the problem.

A rule change designed to reduce concussions in community rugby has had a striking - and uneven - effect. According to research reported by the Irish Independent, the introduction of a lower tackle height law produced a sharp fall in concussions among adult players, but delivered no equivalent benefit in schoolboy rugby. The finding matters because much of the policy rationale for the tackle height change has centred on protecting younger, developing players. If the rule is not working for schoolboys, the question of why - and what to do instead - becomes urgent for schools, coaches, and safeguarding leads across England.

What did the study find?

The research tracked concussion rates before and after the lower tackle height rule was implemented in community rugby. Among adult players, the reduction in concussion incidence was significant - a result consistent with the evidence from the IRFU's two-season tackle behaviour trial, which found a 50% reduction in head contacts when the lower tackle point was applied. That trial, whose results were published in late 2025, formed part of the evidence base behind World Rugby's recommendation to write the lower tackle height into community game law.

Among schoolboys, however, the picture was different. The study found no statistically significant reduction in concussion rates following the rule change in the school-age group. This divergence between adults and schoolboys is the headline finding - and it demands explanation.

Why might the law change work for adults but not schoolboys?

Several factors are likely at play. First, adult players may be better placed to adjust their tackle technique in response to a rule change. They have more experience, more training time, and - at community level - more consistent access to coach-led sessions where technique can be refined. Schoolboys, by contrast, are still developing the physical coordination, spatial awareness, and body control that effective low tackling requires. Asking a 14-year-old to consistently tackle below the sternum in a live match is a different challenge from asking a 30-year-old club player to do the same.

Second, the enforcement environment is different. Adult community rugby has referees who are increasingly attuned to high tackle penalties. School sport fixtures, particularly at junior level, often have less experienced officials, and the culture of calling high tackles may be less consistent.

Third, the physical size differential among schoolboys is often greater than among adult community players. A significant height and weight range within a school-age cohort means that what constitutes "low" for one player may be mid-chest for another - complicating both coaching and officiating.

Finally, there is a training exposure issue. Adult club players typically train several evenings a week and have dedicated conditioning time. Many schools, under curriculum and timetabling pressure, cannot offer the same volume of skills practice. Embedding a technique change requires repetition, and that repetition may simply not be available at school level.

What does this mean for concussion management in school rugby?

The study's finding should not be read as evidence that the lower tackle height law is wrong for schoolboys - the existing evidence base for reducing head contact through lower tackle points remains credible. What it does suggest is that the rule change alone is not sufficient. Coaching quality, training volume, enforcement consistency, and player development all need to move together for a law change to translate into reduced concussion rates on the pitch.

For schools, the practical implication is clear: a rule change in the community game does not substitute for a robust concussion management framework. The two things are complementary, not interchangeable. Even in a world where tackle law is working perfectly, concussions will still happen in school rugby. The question is whether schools are equipped to identify, manage, and document them correctly when they do.

This is where the UK Concussion Guidelines for Grassroots Sport (Sport and Recreation Alliance, November 2024 update) remain the relevant standard. The guidelines apply regardless of the tackle law in force and set a minimum 21-day stand-down for confirmed concussion in under-18s, along with clear removal protocols and a graduated return-to-play pathway.

Schools would also benefit from reviewing their approach to concussion identification in school rugby, including whether staff are trained to recognise the subtler signs of concussion that younger players often display - and are encouraged to mask.

Why are schoolboys harder to protect through rule changes alone?

There is a wider point here about the limits of top-down interventions in school sport. Governing body law changes percolate slowly into school rugby. Teachers and coaches who run school sport are doing so alongside other responsibilities - they are not full-time rugby coaches. Training time is limited. The culture around injury reporting in schoolboy rugby can still, in some environments, discourage players from disclosing symptoms.

None of this is a reason to abandon the lower tackle height law - it is clearly producing benefits at adult level. But it is a reason for schools not to assume that the community game's regulatory framework is doing the job of protecting their pupils. Schools retain their own duty of care, independent of what NGB law says. That duty requires an operational concussion management protocol, not simply adherence to whichever tackle height is currently mandated.

What should schools do now?

The study's finding is, in practical terms, a prompt for schools to act on what they can control directly. Concussion prevention through tackle law is one input into the system; concussion identification and management is another. Schools can act on the latter right now, without waiting for further regulatory change.

Concrete steps worth taking this term include the following.

Review whether all staff involved in school rugby - PE teachers, volunteer coaches, match officials, and first aiders - have completed the RFU's HEADCASE concussion awareness training. This is free, online, and takes around 20 minutes. It covers the signs of suspected concussion and the immediate removal protocol.

Check that your school's concussion policy explicitly covers school rugby fixtures, not just training sessions. Concussions at away fixtures and Saturday morning matches need to be captured in the same documentation trail as incidents on the school pitch.

Ensure that the graduated return-to-play protocol is being followed after every identified concussion - not just the significant-looking ones. A player who seemed "only a bit dazed" still requires the same structured pathway.

Consider whether your approach to coaching tackle technique is keeping pace with the evidence. World Rugby's Tackle Ready programme provides structured progressions for coaching lower tackle height, and these can be integrated into school PE lessons and training sessions.

The honest conclusion

The new study is a valuable contribution to the evidence base - and a useful corrective to any assumption that the tackle height law has resolved the concussion problem in school rugby. It has not, at least not yet, for schoolboys. That creates a clear responsibility for schools to make sure their own concussion management frameworks are sound, documented, and consistently applied.

Rule changes and management frameworks need to work together. At the moment, the evidence suggests the rule change is working for adults. For schools, the management framework is where attention is most needed.
