Former NFL star Chris Johnson, celebrated for his electrifying speed and remarkable career as 'CJ2K,' shared a somber personal update on Monday, June 29, 2026, revealing he has been diagnosed with Amyotrophic Lateral Sclerosis (ALS).
Johnson, 40, made the announcement during a candid television interview on ABC's 'Good Morning America.' The news has sent ripples across the sports world, as fans and former teammates alike process the revelation from one of the league's most dynamic players.
A Career Defined by Speed and Dominance
Chris Johnson carved out a legendary career over 10 seasons in the National Football League. Drafted by the Tennessee Titans in 2008, he quickly established himself as a dominant force, highlighted by his historic 2,006 rushing yards season in 2009, earning him the moniker 'CJ2K.' His ability to outrun entire defenses made him a constant threat and a fan favorite.
Johnson's professional career concluded in 2017, leaving a legacy of explosive plays and record-breaking performances that cemented his place among the NFL's elite running backs.
The Onset of Symptoms and Public Announcement
During his emotional 'Good Morning America' appearance, Johnson disclosed the initial signs that led to his diagnosis. He noted that he first experienced a concerning weakness in his right hand, a symptom that eventually prompted medical evaluation and the subsequent ALS diagnosis.
ALS, often referred to as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, leading to muscle weakness, paralysis, and ultimately, death. Johnson's courage in publicly sharing his battle has been met with an outpouring of support from across the league and beyond.
