Former NFL Star Chris Johnson Opens Up About ALS Risk in Letter to Children
Johnson faces potential ALS diagnosis, a progressive neurodegenerative disease affecting motor function and life expectancy.
A man confronting what his career may have cost him
Mark
Why did Johnson choose to write a letter to his children instead of just making a statement through his agent or a medical team?
Mimi
There's something about the letter format that makes it real in a way a press release never could. He's not performing for the public—he's speaking to the people who matter most to him, and he's doing it where everyone can see. That's a choice.
Luke
But we should be careful here. The source material doesn't actually tell us what Johnson wrote or what he said specifically. We know he reflected on ALS risk in a letter format, but we don't have the actual words or details of his diagnosis status.
Mimi
That's fair. We know he's concerned about risk, but the reporting doesn't confirm he has ALS—just that he's publicly addressing the possibility.
Mark
What makes this moment different from other athletes speaking out about football injuries?
Mimi
ALS is different because it's degenerative and fatal. It's not a concussion you recover from or a joint you rehab. It's a disease that takes everything, slowly.
Luke
And the connection to football is still being studied. We can say there's concern and growing medical attention, but we can't say definitively that football caused his risk. That's important to hold.
Mark
So what does his letter actually change?
Mimi
It keeps the conversation alive. It makes it harder for the league to ignore. And it tells other former players they're not alone in worrying about this.
Luke
It also puts pressure on the NFL to do better with health monitoring and prevention. Whether that translates to actual policy changes is still an open question.
Le Pouls
- A man who built his life on physical mastery now confronts the possibility of losing voluntary control over his own body — the cruelest inversion of an athlete's identity.
- ALS carries no cure and no mercy, progressing until it claims speech, movement, and breath, making Johnson's risk not a distant worry but a present and irreversible horizon.
- The choice to speak through a letter to his children rather than a press release transformed a medical disclosure into something far harder to dismiss — an act of love made public.
- Growing scientific evidence links repeated football impacts to CTE and ALS, yet definitive causation remains elusive, leaving former players in a limbo of probability and uncertainty.
- Johnson's testimony sharpens pressure on the NFL to answer what it owes players whose neurological health may have been permanently altered in service of the game.
Chris Johnson, once celebrated for the speed and power he brought to professional football, has written a letter to his children acknowledging that his years in the sport may have left him vulnerable to ALS — a fatal neurodegenerative disease with no cure. By choosing the intimacy of a family letter as his public vehicle, Johnson placed a human face on a question science and sport have long struggled to answer: what does the game ultimately take from those who give it everything? His disclosure arrives as researchers continue to document troubling connections between professional football careers and long-term neurological disease, adding one more voice to a reckoning the sport cannot indefinitely defer.
Chris Johnson spent his NFL career doing what few could — moving through defenses with a speed that seemed to defy the violence of the sport. Now, away from the field, he is confronting something he could not outrun: the possibility that professional football left him at risk for ALS, a progressive neurodegenerative disease that destroys the motor neurons governing voluntary movement. There is no cure. It is always fatal.
Rather than issue a clinical statement, Johnson chose to write a letter to his children — an intimate, familial form that gave his disclosure an emotional gravity no press release could replicate. He was not addressing the league or the media first; he was addressing the people who will live with his legacy long after the game has faded.
His reflection lands amid deepening scientific concern about what professional football does to the brain and nervous system over time. Researchers have documented links between careers in the sport and chronic traumatic encephalopathy, as well as ALS, though establishing clear causation remains difficult. Former players have reported neurological diagnoses at rates that suggest the connection is more than coincidence.
By naming his own risk publicly, Johnson joined a growing number of former athletes willing to speak plainly about the price their careers may have exacted. His letter does not answer the hard questions — what the NFL owes its players, how the sport must change, how society weighs entertainment against human cost — but it makes those questions impossible to set aside. His children will inherit not only the memory of what he accomplished, but the full knowledge of what it may have cost him.
Chris Johnson, who spent his professional career running through NFL defenses with explosive speed and precision, sat down to write a letter to his children about something he could not outrun: the possibility that the game had left him vulnerable to ALS, a progressive neurodegenerative disease that attacks the nerve cells controlling voluntary muscle movement.
The former star made his concerns public, choosing to address his children directly about the health risks he now faces as a consequence of his years in professional football. Johnson's decision to frame this as a letter—intimate, familial, meant for the people closest to him—gave the disclosure a weight that clinical statements or medical announcements alone could not carry. He was not speaking to reporters or advocates; he was speaking to his own family, and he chose to do it in public.
ALS, also known as Lou Gehrig's disease, is a condition in which motor neurons gradually break down, robbing people of their ability to move, speak, eat, and eventually breathe. There is no cure. The disease progresses at different rates in different people, but it is always fatal. For someone who built his identity and livelihood on physical dominance and control, the prospect of losing voluntary muscle function represents a particular kind of reckoning.
Johnson's public reflection arrives amid growing medical and scientific attention to the long-term neurological consequences of playing football at the professional level. The concern centers not only on acute injuries—the concussions and head trauma that occur during games—but on the cumulative effect of repeated impacts over years of competition. Researchers have increasingly documented connections between football careers and chronic traumatic encephalopathy, a degenerative brain condition, as well as other neurological diseases including ALS. Former players have reported diagnoses at rates that suggest a possible link to their time in the sport, though establishing definitive causation remains scientifically complex.
By writing to his children about his own risk, Johnson joined a growing chorus of former athletes willing to name the price they may be paying for their careers. His letter serves as both a personal document and a public statement—a way of saying to his family that he understands what may lie ahead, and simultaneously a way of pushing the broader conversation about player safety and long-term health monitoring in professional football into sharper focus.
The disclosure raises questions that the NFL and its players have grappled with for years: What do teams and the league owe players whose bodies and brains have been altered by the game? How should the sport change to protect current and future players? And how do we account for the human cost of entertainment when that cost is measured in years of life and quality of living?
Johnson's letter does not provide answers to those questions. What it does is make them impossible to ignore. A man who gave his physical gifts to professional football is now confronting the possibility that those gifts came with an expiration date he did not choose and cannot control. His children will inherit not just his legacy as a player, but the knowledge of what that legacy may have cost him.
