Former NFL running back Chris Johnson, known for his record-breaking 2,006-yard rushing season in 2009, revealed he has been diagnosed with amyotrophic lateral sclerosis (ALS). The 40-year-old Johnson, who played for the Tennessee Titans, New York Jets, and Arizona Cardinals, shared the news in an interview with Michael Strahan on ABC's "Good Morning America." He was diagnosed with ALS in 2025 and has since lost the ability to speak, relying on a speech-generating device to communicate.
Johnson emphasized his determination to fight the disease, stating, "At first, you're in shock. Then you realize you have two choices: You can give up or you can fight. I chose to fight." He first noticed symptoms in his right hand, which gradually weakened, leading to his diagnosis. There is no known cure for ALS, and the average life expectancy after diagnosis is three to five years, though some patients survive longer.
Johnson's diagnosis has sparked an outpouring of support from the NFL community, including former teammates, coaches, and fans. The Tennessee Titans, where Johnson spent the majority of his career, expressed their support, calling him one of the most impactful players in franchise history. Other teams, including the Arizona Cardinals and New York Jets, as well as East Carolina University, also sent messages of encouragement.
ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, leading to the loss of muscle function. Johnson is participating in clinical trials to slow the progression of the disease. His wife, Brittany Johnson, has been a significant source of support, helping him navigate the challenges of living with ALS.
Johnson's revelation has brought attention to the disease, which affects approximately 30,000 Americans. He hopes his story will inspire more research and awareness about ALS.
