Former NFL star Chris Johnson reveals ALS diagnosis at age 40
Former NFL star Chris Johnson has announced a diagnosis of sporadic ALS at age 40. He is participating in clinical trials while advocating for more research.
Former Tennessee Titans running back Chris Johnson, a celebrated figure in professional football known for his historic speed, announced on Monday, 29 June 2026, that he has been diagnosed with amyotrophic lateral sclerosis (ALS). The revelation occurred during a televised interview on Good Morning America, where the 40-year-old athlete utilized a speech-generating device controlled by eye movements to communicate with host Michael Strahan.
Johnson, who earned the nickname “CJ2K” after a record-setting 2009 season, received the diagnosis in 2025 at age 39. He is currently navigating the realities of sporadic ALS, the most common form of the neurodegenerative disorder which occurs in patients with no known family history. Medical professionals, including Dr. Merit Cudkowicz of the Mass General Brigham Neuroscience Institute, have been overseeing his care. Johnson’s treatment plan has included both standard medications aimed at slowing the progression of the illness and participation in a clinical trial focused on reducing inflammation.
Media additions
The transition from a life of elite athleticism to the rapid onset of ALS symptoms has been stark. Johnson, who retired from the NFL in 2017 after a 10-season career with the Titans, New York Jets, and Arizona Cardinals, initially noticed early warning signs in his daily life. "At first it was little things like my grip didn't feel right, and I wasn't as strong as I'd always been," Johnson said. His wife, Brittany Johnson, initially attributed the weakness to his long football career, suspecting a condition such as a pinched nerve rather than a terminal disease.
Life With ALS
The progression of the disease has been swift. Just over a year ago, Johnson was physically capable of lifting his 7-year-old daughter to help her make a wish over a birthday cake; today, his physical limitations prevent such actions. Despite the loss of his ability to speak and the physical deterioration of his body, Johnson emphasizes that his identity remains unchanged.
"I want people to know that I'm still me. ALS has changed what my body can do, but it hasn't changed who I am."

He expressed a desire to challenge societal perceptions of those living with physical disabilities. "People sometimes look at the physical disability and assume you're not the same person," he noted. "I still think the same. I still dream. I still love my family. My body just doesn't cooperate."
A Support System
Johnson credits his wife and their four children as the primary motivation for his continued determination. Brittany Johnson, who has served as his caregiver throughout the diagnosis, described the shift in their family life as a heavy, yet necessary, responsibility. "Our life has shifted so much and it's a heavy workload, but I have no doubt that this is what I was called to do," she stated.
The Tennessee Titans organization has pledged its ongoing support for their former star. In a statement, controlling owner Amy Adams Strunk lauded Johnson’s legacy, noting that his leadership on the field and impact within the Nashville community have secured his place in the franchise's history.
Understanding the Diagnosis
The following table provides context on the condition as reported by medical sources:
| Factor | Details |
|---|---|
| Disease Type | Sporadic ALS (90% of cases) |
| Common Symptoms | Muscle weakness, atrophy, respiratory issues |
| Typical Prognosis | 3 to 5 years (with 1 in 10 surviving 10+ years) |
What to Watch Next
- Research Initiatives: A dedicated research effort has been established at the Sean M. Healey & AMG Center for ALS to honor Johnson and further the search for a cure.
- Clinical Participation: Johnson continues to undergo experimental treatments and intends to remain an active participant in clinical trials to assist medical researchers.
- Public Advocacy: By going public, Johnson hopes to inspire earlier detection and encourage increased investment in ALS research, noting, "If sharing my story helps even one person get diagnosed sooner, inspires more research or gives another family hope, then it's worth it."
As the Sports world reacts to the news, the broader community has joined the Titans in expressing support for the former running back. Johnson remains steadfast in his choice: to continue the fight despite the lack of a current cure.
