Former NFL running back Chris Johnson announced Monday that he has been diagnosed with amyotrophic lateral sclerosis (ALS) [1].
Johnson is one of the most decorated rushing talents in professional football history. His public disclosure brings attention to a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, highlighting the challenges faced by former athletes dealing with chronic illness.
During a segment on Good Morning America, the 39-year-old athlete [4] said he received the diagnosis in 2025 [2]. Also known as Lou Gehrig's disease, ALS leads to the loss of muscle control and eventually affects the ability to speak, eat, and breathe.
Johnson played for several teams during his career, including the Tennessee Titans, New York Jets, and Arizona Cardinals [1]. He is widely remembered for his explosive speed and record-breaking performances. In the 2009 season, he rushed for 2,000 yards [5] — a milestone that remains a significant benchmark in league history.
Throughout his career, Johnson earned three Pro Bowl selections [3]. He said he chose to share his diagnosis to inform the public about his condition and to increase awareness of the disease.
The announcement comes as part of a broader effort to educate others on the symptoms and progression of ALS. By using his platform as a former sports star, Johnson aims to support research and resources for those living with the condition.

The disclosure by a high-profile former athlete like Chris Johnson often leads to a surge in public awareness and funding for ALS research. Because ALS is a rare disease with no known cure, the visibility provided by public figures can accelerate the identification of symptoms in others and drive legislative or philanthropic support for neurodegenerative disease treatments.
