Agnes MaxwellTwenty-one-year-old British heavyweight Moses Itauma steps into the ring against American contender Jermaine Franklin on 28 March 2026 at Co-op Live Arena in Manchester — a bout that places the sport's most electrifying young talent back under the spotlight, and puts the science of boxing brain injury firmly in the public conversation.
Itauma carries 13 professional fights and 11 knockouts into this contest. Franklin, 32, has 24 wins and just two losses — both against elite opposition including Anthony Joshua. The build-up has been intense. But beyond the ticket sales and the hype, a pressing medical question accompanies every major boxing event: what is the cumulative toll on the brain?
Boxing and Brain Injury: What the Research Shows
The statistics are stark. According to the Association of Neurological Surgeons, approximately 90 per cent of professional boxers sustain at least one concussion over the course of their career. Around 20 per cent develop some form of chronic traumatic brain injury. These are not hypothetical risks — they are career probabilities.
Concussion in combat sport occurs when the brain moves rapidly inside the skull, typically following a direct blow to the head or jaw. The resulting neurological disruption can produce symptoms that appear immediately or — critically — emerge hours or even days after the impact. This delayed onset is one reason the condition is so frequently underestimated.
Common symptoms to recognise include persistent headache, dizziness, confusion, memory lapses, nausea and sensitivity to light or sound. These are warning signs that warrant prompt medical attention, not a return to training.
When Warning Signs Demand Emergency Care
There is a difference between concussion symptoms that require a GP visit and those that require an ambulance. Red flag signs indicating a potentially serious brain injury include:
- Severe neck pain immediately after impact
- Repeated vomiting
- Seizure or loss of consciousness
- Progressive worsening confusion
- Weakness or numbness in the limbs
- Unequal pupil size
If any of these appear — whether in a professional athlete, an amateur boxer, or someone who has sustained a head impact in any context — emergency care is required without delay. The NHS recommends calling 999 or going directly to A&E. Do not wait to see if things improve.
For symptoms that are present but not acute, the standard medical guidance is to seek review within 48 to 72 hours of injury. A GP or sports medicine specialist can assess neurological function, advise on rest protocols and determine whether specialist referral is appropriate.
The Long Shadow of Repeated Impacts
The longer-term concern in boxing — and in many contact sports — is chronic traumatic encephalopathy (CTE), a progressive neurodegenerative condition linked to repeated head trauma. CTE has been associated with symptoms including memory loss, impaired judgement, aggression, depression and, in advanced cases, dementia.
Research into CTE has accelerated over the past decade. While the condition can currently only be confirmed post-mortem through brain tissue analysis, living athletes with histories of repeated concussion are increasingly monitored for early markers. Studies have identified CTE neuropathology in former professional boxers, and sports governing bodies have responded with stricter protocols — though debate continues about whether current safeguards go far enough.
For amateur athletes, recreational boxers and gym-goers who enjoy sparring, the risk calculus is different from elite competition but not absent. Headgear reduces certain injuries but does not eliminate concussion risk. Anyone who sparres regularly and experiences recurring headaches, concentration difficulties or mood changes should consult a sports medicine doctor rather than dismissing symptoms as "part of the sport."
What Fans and Amateur Fighters Should Do
Moses Itauma's fight on 28 March will draw millions of viewers and inspire a fresh wave of gym sign-ups. That enthusiasm is entirely welcome — boxing builds discipline, fitness and mental resilience. But it should come with honest information.
If you train in boxing or any combat discipline:
- Never return to sparring after a blow that causes any concussion symptom, even mild
- Follow the graduated return-to-sport protocol recommended by the British Association of Sport and Exercise Medicine (BASEM)
- Discuss your training history openly with your GP, especially if you have sustained multiple head impacts
According to guidelines published by BASEM, a minimum of 14 days complete cognitive and physical rest is recommended following a diagnosed concussion, with stepwise return to exercise only after full symptom resolution. Any concussion in a person under 18 requires more conservative management and should always involve a doctor.
The spectacle of professional boxing is compelling. The science behind it is equally important. As Itauma and Franklin trade blows in Manchester this weekend, the medical community will be watching with a different kind of attention — tracking what we are still learning about how the brain absorbs punishment, and how long it takes to recover.
A sports medicine doctor or neurologist can provide personalised advice for anyone concerned about their own head injury history or the risks associated with combat sport training. Early consultation is always preferable to managing long-term consequences.
