Gordon McQueen: The Verdict Is In. Sport Can No Longer Look Away from Brain Injury.

The science of brain injury is no longer disputed

Brain injury in sport is not typically driven by one big hit. Instead, from repetitive exposure to small-force head impacts, which produce no signs or symptoms of concussion, known as sub-concussions.

Every head impact involves rotational forces. These forces cause the brain to rotate inside the skull, stretching and shearing neurons and tiny blood vessels. Over time, this microscopic damage eventually disrupts neural networks, breaks down the blood–brain barrier, and triggers devastating damage and neuro-inflammation; a common feature in neurodegenerative diseases such as CTE, Parkinson’s disease and motor neurone disease (MND).

Sub-concussions are now understood to be a primary driver of long-term brain injury. They occur hundreds of times more frequently than concussions and go unnoticed, unmanaged and unprotected ^[1].

This mechanism is well established in neuropathology and neuroradiology. As Dr Emer MacSweeney, a global expert on brain health, explains, CTE develops through cumulative exposure to repeated, symptomless head impacts, not through isolated concussions ^[2].

This was never about one person, or one type of impact

As we outlined in our original article, Gordon McQueen: Heading in the Spotlight, focusing solely on heading the ball risks misunderstanding the problem.

Biomechanical analysis published in the British Journal of Sports Medicine shows that heading accounts for only around 13% of head impacts in football. The remaining 87% arise from other sources: head-to-head contact, falls, collisions with knees, elbows, the ground or goalposts ^[3].

The common factor across all of these is not the ball. It is rotational force and sub-concussions.

This is why the McQueen ruling is not just relevant to strikers, defenders, professional footballers, or even football itself. The same exposure profile exists across rugby, hockey, netball, basketball, lacrosse, cricket, combat sports, and all other contact and collision sports.

It affects every player, at every level, and it starts in youth sport, during critical stages of brain development.

Measurement and rule changes are not enough

Sport’s response to brain injury has focused almost exclusively on detection and management after brain injury has already occurred. Concussion protocols, head injury assessments (HIA), removal-from-play rules, and concussion tracking systems all operate after damage has been done.

Detection does not protect the brain. It only tells us that injury has likely already occurred.

Similarly, rule changes; limiting heading, modifying techniques, adjusting training loads; may reduce certain exposures, but they only address part of the problem. Head impacts will still happen. Collisions, falls and accidental contact cannot be officiated or coached away.

If the aim is to reduce long-term brain injury risk, the focus must shift from reactive management to brain protection starting in youth.

Protection means reducing rotational forces and cumulative sub-concussion damage

The most meaningful mitigation available is clear: reduce the transmission of rotational forces and sub-concussions to the brain, across all head impacts, all training and competition, all sports and for all ages.

This is not opinion. It is biomechanics.

Reducing rotational forces reduces the tearing of brain cells and blood vessels, lowers neuro-inflammation, and reduces cumulative exposure; the key driver of neurodegenerative risk ^[4].

Rezon Halos® exists because sport has failed to act

For decades, sport protected what it could see: shins, teeth, scalps. The brain was overlooked.

Rezon Halos® was developed because that failure could no longer be ignored.

Halos® is intentionally engineered to reduce rotational forces transmitted to the brain in both concussive and sub-concussive impacts. Independent testing shows:

• rotational forces reduced by up to 61%
• concussion risk reduced by 74%
• the highest 5-star Virginia Tech rating
• Halos® is the only CE / UKCA Category II PPE certified protective headband, the legal standard for protective equipment in the UK and Europe

This is brain protection, not scalp protection. This is protection, not reacting to brain damage after it occurs.

Time to wake up

The Gordon McQueen ruling should end any remaining debate about whether repetitive head impacts damage the brain. That question has been answered.

What remains is a decision.

Continuing to focus solely on concussion, or on isolated skills like heading, is no longer defensible. The science is clear. The risk is cumulative. The mechanisms are rotational forces and sub-concussions.

We now know the problem. We now have a medically endorsed and independently tested option for brain protection.

If sport chooses not to act, responsibility will no longer lie with history or ignorance. It will lie with limiting brain protection choice.
