Fainga'anuku's Head Knock and What Concussion Protocols Really Mean for Grassroots Rugby

Key takeaways

• Caleb Fainga'anuku received a head knock during international rugby, sparking fresh debate about how concussion decisions are made in real time.
• Elite head injury assessment (HIA) protocols are built for environments with pitchside medics and video review. They do not apply directly to grassroots or school rugby.
• The UK Grassroots Concussion Guidelines (November 2024 update) set the standard for community and school sport. The rule is simple: if in doubt, sit them out, with a minimum 21-day stand-down for under-18s.
• High-profile cases are a useful prompt to check whether your club or school protocol is actually operational, not just written down.
• The pressure players feel to carry on, even at elite level, is just as real at grassroots level. Coaches need language and structures that remove that pressure from the player.

Analysis from 1News and commentary from rugby writers this week has turned attention back to how concussion calls are made at the sharp end of the sport. Caleb Fainga'anuku's head knock during international rugby, and the scrutiny that followed it, is a reminder of something the grassroots game knows well: the moment of decision is hard, fast, and high-stakes. What elite coverage rarely does is translate those lessons into what they mean for a school coach or community club welfare officer. This article does that.

What happened, and why it matters beyond the top level

Reports from 1News and Planet Rugby this week described Fainga'anuku sustaining a head knock during play, with commentators and analysts questioning how concussion decisions were handled at pitchside. The Bordeaux president was quoted as being "very scared" for the player's future in the sport, and World Rugby's protocols were cited across multiple outlets.

The specific medical details of Fainga'anuku's case are not publicly confirmed, and Luca does not speculate about individual athletes' medical histories beyond what named outlets have reported. What we can say is this: whenever a high-profile incident like this surfaces, grassroots coaches and school sports staff often ask whether it changes anything for them. The honest answer is: probably not in terms of what the rules require, but it is a useful prompt to check whether what the rules require is actually happening at your level.

Why elite protocols do not translate directly to the community game

The World Rugby Head Injury Assessment (HIA) is the elite-level protocol. It involves trained pitchside medics, video review technology, and a structured process that can temporarily remove a player from the field while assessment takes place. It is designed for an environment with significant medical resource on hand.

That is not the environment at a Saturday morning school fixture or a community club training session.

The framework that applies at grassroots level in the UK is the UK Concussion Guidelines for Grassroots Sport, last updated by the Sport and Recreation Alliance in November 2024. These guidelines are built around a single principle: if there is any suspicion of concussion, the player comes off immediately and does not return to play that day. There is no equivalent of the HIA's temporary substitution and return mechanism at grassroots level, because the medical resource needed to make a safe same-day return decision is simply not there.

This distinction matters. One of the most common mistakes at grassroots level is coaches or parents citing elite-level decisions as justification for different treatment at community level. The two systems are structurally different, and for good reason.

What the November 2024 UK Grassroots Guidelines actually require

The November 2024 update to the UK Grassroots Concussion Guidelines tightened the stand-down periods and clarified the pathway. The key rules are:

• Immediate removal. Any player suspected of concussion must be removed from play immediately. They do not return to contact sport that day under any circumstances.
• Minimum stand-down periods. Adults must stand down for a minimum of 14 symptom-free days before completing a graduated return to sport. Under-18s must stand down for a minimum of 21 days, with symptom-free status required before the graduated return begins.
• Graduated return to sport (GRAS). Return is staged, not a single clearance. Each stage requires symptom-free completion before moving to the next. The full pathway, from removal to return to contact, takes a minimum of six weeks for under-18s when the stand-down and GRAS stages are combined.
• Clinical sign-off for return to contact. Under the November 2024 update, a healthcare professional should be involved in sign-off for return to full contact activity. For schools and clubs without direct access to a team doctor, this typically means a GP appointment.

The Luca graduated return to play pathway at /how-it-works/ structures each of these stages with documentation and clinical oversight, which is particularly important for organisations that run multiple teams across age groups.

The pressure problem: why "if in doubt, sit them out" is harder than it sounds

The Fainga'anuku coverage this week touched on a dynamic that is familiar at every level of the sport: the pressure on players, and those around them, to minimise the significance of a head knock and carry on. This pressure is cultural, competitive, and in the moment it is very real.

At elite level, the stakes are contracts, selection, and careers. At grassroots level, the stakes feel different but the dynamic is similar. A young player does not want to let their team down. A coach does not want to be seen as overcautious. A parent at the side of the pitch wants to believe their child is fine.

The November 2024 UK guidelines are explicit that the decision to remove a player is not negotiable once suspicion of concussion is present. The coach, teacher, or welfare officer does not need to diagnose concussion. They need to identify suspicion. Suspicion is enough. The guideline language is clear: "if in doubt, sit them out."

Coaches should know the signs that trigger removal. These include any of the following, per the Sport and Recreation Alliance guidance:

• Loss of consciousness, however brief
• Confusion or disorientation
• Visible impact seizure or convulsive movements
• Unsteadiness on feet, balance problems
• Dazed appearance or slow response to questions
• Clutching or holding the head
• Any reported headache, nausea, or vision problems following a head impact

You do not need all of these. One is enough.

What coaches and school sports staff should do after an incident like this

High-profile concussion incidents in elite sport are, if nothing else, a useful reason to revisit your own practice. Here is a practical check for this week:

1. Review your immediate-removal procedure. Who makes the call? What happens if the designated welfare officer is absent? Is there a clear deputy?

2. Check your documentation trail. When a player is removed for a suspected concussion, is that incident recorded in writing within 24 hours? Who holds that record?

3. Confirm your stand-down tracking. If a player was removed last season and never formally completed the GRAS pathway, are you aware of that? A record system makes this visible.

4. Revisit your player and parent communication. Do players know that they are protected by the removal rule, not penalised by it? Does your pre-season briefing include this?

5. Check clinical sign-off arrangements. For return to contact activity, under the November 2024 update, a healthcare professional should be involved. Is that route clear for your players and families?

The Luca Safe Concussion Framework covers all seven of these operational domains, and is free to download from /lscf/.

The longer picture: why protocols exist

Fainga'anuku's situation has also attracted commentary about long-term career risk. Without knowing the specifics of his case, what we can say is that the science supporting stand-down protocols is about more than immediate safety. Concussion recovery involves a period of neurological vulnerability during which a second impact, even a minor one, carries disproportionate risk. Return-to-play protocols exist because the window of recovery is not visible from the outside. Feeling fine is not the same as being recovered. That is as true for a 17-year-old in a school first XV as it is for an international winger.

The UK Grassroots Guidelines and World Rugby's community game guidance are built on this evidence. Following them is the most straightforward thing a club or school can do to protect their players.
