Former NFL running back Chris Johnson, a three-time Pro Bowler and former league rushing leader, has publicly announced he has been diagnosed with Amyotrophic Lateral Sclerosis (ALS). The 40-year-old, who earned the nickname "CJ2K" after rushing for 2,006 yards during the 2009 season, confirmed the diagnosis in an interview on ABC’s Good Morning America.
The Diagnosis and Impact on Daily Life
Johnson revealed that he received the diagnosis last year after undergoing extensive medical testing. ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord. As the motor neurons degenerate, the brain loses the ability to initiate and control muscle movement.
In his interview with Michael Strahan, Johnson utilized a voice modulator to communicate, as the disease has already impacted his ability to speak. He noted that the progression of his symptoms has been rapid. "Just over a year ago, I was picking up my seven-year-old daughter so she’d make a wish with her birthday cake," Johnson said. "Today, I couldn’t do that."
Understanding ALS and Sporadic Diagnosis
Johnson stated that his doctors classified his condition as "sporadic ALS." The vast majority of ALS cases are sporadic, meaning there is no known family history of the disease. A small percentage of cases are inherited through a genetic mutation.
There is currently no cure for ALS. The disease is frequently referred to as "Lou Gehrig’s disease," named after the New York Yankees legend who was forced to retire from the game after being diagnosed with ALS.
A Career Defined by Speed
Before his diagnosis, Johnson was recognized as an explosive player in professional football. Drafted 24th overall by the Tennessee Titans in the 2008 NFL draft out of East Carolina University, he quickly became a centerpiece of the Titans’ offense.
- 2009 Season: Johnson led the NFL with 2,006 rushing yards, a performance that earned him the "CJ2K" moniker.
- NFL Tenure: Over a 10-year career, Johnson recorded 9,651 rushing yards and 55 touchdowns. He made 130 appearances, starting 111 games.
- Team History: After five seasons with the Tennessee Titans, he played for the New York Jets in 2014 and the Arizona Cardinals the following year.
- Retirement: Johnson first retired from the NFL after 10 years in the game in November 2018, before signing a one-day contract to retire as a Tennessee Titan in April 2019.
Advocacy and Awareness
Johnson said he decided to share his medical journey to provide hope for other families and to emphasize the importance of early detection. Despite the physical limitations imposed by the disease, Johnson remains focused on his identity outside of his diagnosis.
"I want people to know that I’m still me," Johnson 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."
