NFL Star Chris Johnson Chooses to Fight After ALS Diagnosis

Former NFL star Chris Johnson is showing the world what courage looks like after revealing his ALS diagnosis on Good Morning America this week.

The 40-year-old former Tennessee Titans running back, known as CJ2K for his legendary 2,006-yard rushing season in 2009, received his diagnosis in 2025. He's now using a speech-generating device based on recordings of his own voice to communicate.

"At first, you're in shock," Johnson said. "Then, you realize you have two choices. You can give up, or you can fight. I chose to fight."

Johnson first noticed something was wrong when his grip weakened. The changes came fast. Just over a year ago, he was lifting his 7-year-old daughter to make a birthday wish over her cake. Today, he can't hold a cup or speak without assistance.

His wife Brittany initially thought the symptoms might be related to his football career, maybe a pinched nerve. Neither imagined it would be ALS, also known as Lou Gehrig's disease, which affects nerve cells that control muscles throughout the body.

Johnson has no family history of the condition. His doctors believe he has sporadic ALS, which accounts for the vast majority of cases and can strike anyone without warning.

Why This Inspires

Johnson went public with his diagnosis for two powerful reasons: to raise awareness about how quickly ALS can progress and to remind people that physical disability doesn't change who you are inside.

"I want people to know that I'm still me," he said. "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."

His courage is already making waves. The Titans, Cardinals, Jets, and NFL Players Association have all rallied behind him with messages of support. His former teammate Tim Shaw, who was diagnosed with ALS in 2014 at age 30, is still alive and fighting today.

Johnson is participating in a clinical trial as part of his treatment. He's also calling on the NFL to invest in research, especially given that Boston University studies show pro football players are four times more likely to develop ALS than other adult males.

"Together, we can push toward better treatments and, one day, a cure," Johnson said on Instagram.

His message is landing exactly where it needs to: with researchers, the NFL, and anyone facing their own impossible battle who needs to see someone choose to fight.
