MMA vs Boxing: Which Sport Has More Fatalities?
MMA enthusiasts and combat sports lovers often debate and compare MMA wBoxingxing to determine which sports are more dangerous.
MMA might seem more dangerous in plain eyes as it uses a wide range of attacks, such as punches, kicks, knees, and elbows, while Boxing uses only fists.
But in reality, most MMA matches end up with grappling. In contrast, Boxing players can sustain several fatal blows to the head that can have long-term impacts on health.
Let me give you some statistics about how many deaths have occurred in both these sports:
A Comparison of Death Rates in Combat Sports
Boxing has long been known for its risk of head trauma, and unfortunately, it’s a sport where fatalities are common.
On the other hand, MMA is Thought of as a dangerous combat sport, But the statistics say differently.
- Boxing: According to the Manuel Velazquez Boxing Fatality Collection report, Boxing fatalities have been happening for over a century, with more than 1,600 documented deaths in the sport.
- MMA: In contrast, MMA has seen around 20 fatalities. And in recent years, the number has become smaller.
One significant difference between the two sports is the variety of techniques involved.
Boxing is a stand-up sport focused on punches, whereas MMA includes strikes, grappling, and submissions.
The variety in MMA’s combat styles means fighters are at risk from different types of injuries, including not just head trauma but also joint and ligament damage.
The Causes Behind MMA Deaths

While it’s easy to think of MMA deaths as simply the result of one big knockout or injury, the reality is far more complex. Several factors can contribute to fatalities in the sport. Let’s break down some of the leading causes of MMA deaths.
1. Brain Injuries and Knockouts
One of the most common causes of death in MMA is brain injuries. Knockouts, especially those caused by headshots, can lead to traumatic brain injuries (TBI) that may not show symptoms immediately. When fighters are knocked out, their brains suffer a rapid deceleration, which can cause severe damage. Sometimes, these injuries aren’t immediately fatal but can lead to brain hemorrhages or strokes days or even weeks later.
2. Chronic Traumatic Encephalopathy (CTE)
Chronic Traumatic Encephalopathy is a neuro-linked health issue that results from repeated hits to the head, especially on the temple and the rear side of someone’s head.
It’s been heavily discussed in boxing and MMA due to its long-term effects. CTE can cause symptoms like memory loss, depression, and even violent behavior. In severe cases, it can lead to death.
3. Underlying Medical Conditions
Sometimes, a fighter’s death may be linked to pre-existing health conditions.
For example, Anthony Johnson’s death was reportedly related to an illness he had been fighting for a while.
If you have Heart conditions, high or low blood pressure, or other complex health issues, you better check with a doctor before even considering stepping into Octagon.
