Chris Johnson ALS Diagnosis: Former Titans RB Opens Up on Battle With Lou Gehrig’s Disease

Former Tennessee Titans running back Chris Johnson has revealed he was diagnosed with ALS last year at age 39. In a powerful sit-down with Michael Strahan that aired Monday on Good Morning America, the three-time Pro Bowl back shared how the disease struck without warning and why he has chosen to fight.

Johnson, the explosive back known as CJ2K who torched defenses for the Titans and later the Cardinals, was in the prime of his life when symptoms first appeared. He noticed weakness in his right hand during daily workouts. Simple things like his grip feeling off or losing strength he had always taken for granted. His wife, Brittany, initially suspected something tied to his football career — maybe a pinched nerve from years of punishing runs and hits. Neither expected ALS.

“There’s no history of ALS in my family,” Johnson said. “My doctors believe my case is what’s called sporadic ALS, which is actually how the vast majority of ALS cases happen. That’s one of the reasons this disease can be so shocking. It can happen to someone who never expected it.”

The diagnosis landed like a thunderclap. Doctors told the couple a medication might buy a few extra months and advised them to get their affairs in order. Johnson described the initial shock, then the moment everything crystallized: two choices — give up or fight. He chose to fight.

The Speed of the Fight

ALS has moved faster than anyone imagined. Just over a year ago Johnson was lifting his 7-year-old daughter so she could blow out birthday candles. Today he cannot do that. He now communicates through an eye-tracking speech-generating device programmed with recordings of his own voice. Even holding a cup has become difficult despite early detection and aggressive treatment.

“It’s continued to progress much faster than I ever imagined,” he said. “I want people to understand just how quickly ALS can attack your body.”

Yet the man inside remains unchanged. “I want people to know that I’m still me,” Johnson emphasized. “ALS has changed what my body can do, but it hasn’t changed who I am. I still think the same. I still dream. I still love my family. My body just doesn’t cooperate.”

Reaching for Hope Through Research

After watching a GMA segment featuring the late actor Eric Dane and Dr. Merit Cudkowicz, Johnson and his wife reached out to the renowned ALS researcher at Mass General Brigham. Cudkowicz offered experimental options and a more creative approach to care. Johnson has been on standard medications plus a clinical trial therapy aimed at reducing inflammation. Cudkowicz noted the trial participation appears to have helped.

Johnson’s story is already sparking action. A research fund in his name has launched at the Sean M. Healey & AMG Center for ALS to accelerate new treatments and early detection efforts.

Family at the Center

Through every shift — the heavy caregiving load, the uncertainty — Brittany Johnson has stayed by his side. “Our life has shifted so much,” she said. “It’s a heavy workload… But I have no doubt that this is what I was called to do.”

Johnson draws daily strength from their four children. “My kids are also a huge part of why I keep going,” he said. “Every day I wake up wanting more time with them to make more memories and just be their dad. They give me a reason to keep fighting.”

The NFL Family Responds

Tennessee Titans owner Amy Adams Strunk released a statement of support: “Some people leave a mark on an organization that you just can’t put into words. Chris Johnson is one of those people for us… We will support Chris every step of the way throughout his journey. We are holding him and his family close.”

Teammates, former players, and the broader football community have rallied around the news. Johnson’s courage in going public is already being credited with raising urgent awareness for a disease that still has no cure.
