Chris Johnson discloses ALS diagnosis in a personal update from Cardinals franchise

Former Arizona Cardinals running back Chris Johnson revealed that he has been diagnosed with ALS, Lou Gehrig’s disease, in an update published by the team on June 29, 2026. Johnson’s message brings a rare kind of focus to the NFL’s offseason routine, underscoring how serious neurological conditions can affect athletes long after their playing days end.

Johnson’s NFL career spanned 10 seasons, and he spent three of those years with the Cardinals. The franchise has framed his time in Arizona as part of a stronger run that included the 2015 Cardinals team, which advanced to the NFC Championship Game. That run remains one of the more prominent postseason storylines tied to Johnson’s tenure in Phoenix.

Beyond the football timeline, Johnson’s disclosure places him in the small, well-known group of former professional athletes who have publicly shared ALS diagnoses. ALS is a progressive disease that affects nerve cells in the brain and spinal cord, leading over time to muscle weakness and loss of voluntary movement. Public awareness efforts often emphasize the importance of early recognition, research funding, and support for patients and families.

The Cardinals’ announcement does not recast Johnson’s past accomplishments or attempt to connect the disease to his playing career. Instead, the emphasis is on the diagnosis itself, a personal development that will likely reach beyond football audiences and draw attention from fans who remember Johnson’s impact in the regular season and in a Cardinals postseason run.

From a league perspective, high-profile health disclosures from former players can influence how teams and the NFL community think about long-term player wellness. They can also affect charitable and educational attention around neurological disease, particularly when announcements come from major sports organizations like the Cardinals.

Looking ahead, the main thing to watch is how Johnson’s update translates into public conversation and support initiatives. The Cardinals, as his former team, will likely remain a focal point for fans seeking updates, while ALS advocacy groups may see renewed attention due to the visibility of an NFL alumnus speaking directly about his diagnosis.
