Former Tennessee Titans running back Chris Johnson has revealed he can no longer speak on his own after being diagnosed with ALS, also known as Lou Gehrig's disease, in a Good Morning America interview with Michael Strahan. He now uses a speech‑generating device triggered by his eyes to communicate, following a fast‑progressing diagnosis in 2025 that doctors initially said might only extend his life by a few months. The three-time Pro Bowl selection, now 40, said he moved quickly to get his affairs in order.
Last year he was lifting his seven‑year‑old daughter to help her make birthday wishes; today he cannot do so, highlighting how quickly the disease has attacked his body and muscle control. ALS is a fatal neurodegenerative disease that destroys nerve cells controlling voluntary movement, speech and muscle function, according to the ALS Association.
Johnson's Lost Voice and Eye-Controlled Device
Johnson first noticed symptoms last year when his right‑hand grip 'didn't feel right' and felt weaker than usual despite remaining active after retiring from professional football. Doctors diagnosed him with sporadic ALS, which usually occurs without family history or a known cause.
His voice was recorded soon after the diagnosis so the speech‑generating device can mirror his natural voice for everyday communication. Johnson cannot speak naturally now and uses eye‑tracking technology to trigger the device when speaking with his family and medical team. He described the change as one of the most difficult parts of the illness, saying that losing his voice had made simple conversations much harder.
Family Motivation and Treatment Journey
Johnson said his four children give him a powerful reason to keep fighting ALS. In his emotional Good Morning America interview, he said his kids are 'a huge part of why I keep going' and that he wakes up wanting more time to make memories with his wife, Britney, and their children.
He is taking part in a clinical trial at Massachusetts General Hospital and receiving multiple medications intended to help slow the disease's progression. Johnson said seeing other patients seek experimental treatment inspired him to do the same. His wife Britney initially hoped his symptoms were linked to old football injuries. 'We hoped it was something else, but after thorough testing, they finally came down with a diagnosis of ALS,' she said.

Johnson decided to make his diagnosis public partly to encourage earlier testing for others, saying: 'I want people to know I'm still me. ALS has changed what my body can do, but it hasn't changed who I am.' He wants people to understand just how quickly ALS can attack the body and why recognising early signs matters.
