Former NFL running back Chris Johnson has publicly disclosed his diagnosis of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease.
The 40-year-old announced the news during an interview on ABC's "Good Morning America" on Monday, June 29, 2026.
Johnson, who played primarily for the Tennessee Titans and was named to three Pro Bowls, revealed he was diagnosed last year.
He first noticed symptoms in his right hand, such as a weakened grip, before undergoing extensive medical testing.
"At first, it was little things like my grip didn't feel right and I wasn't as strong as I've always been," Johnson said.
The disease, often referred to as Lou Gehrig's disease, affects nerve cells in the brain and spinal cord that control voluntary muscle movements.
Johnson now uses a speech-generating device to communicate.
There is no known history of ALS in his family, which he noted adds to the shock. "It can happen to someone who never expected it," he said.
After his diagnosis, Johnson sought guidance from Dr. Merit Cudkowicz, a specialist he saw in an interview with actor Eric Dane, who died from ALS in February.
Johnson praised her willingness to explore experimental treatments.
"She was willing to think more creatively, offering experimental treatments that might help and advance research," Johnson said.
"That changed the course of our fight."
Despite early diagnosis and multiple experimental therapies, Johnson's condition has progressed rapidly. He can no longer perform basic tasks like holding a cup.
"I want people to understand just how quickly ALS can attack your body," he said.
"I can't even hold a cup if I try, and that's despite being diagnosed relatively early."
By sharing his story, Johnson hopes to accelerate diagnosis for others and push for better treatments. "That's why early detection, more research, and better treatments are so important.
We have to give people a better chance than what's available today," he said.
Johnson emphasized that while his physical abilities have declined, his mind and emotions remain unchanged. "I still think the same.
I still dream. I still love my family," he said.
Johnson retired after the 2017 season, having also played for the New York Jets and Arizona Cardinals.
He led the NFL with 2,006 rushing yards in 2009 and set a league record with 2,509 yards from scrimmage that season.
