Chris Johnson, the former NFL running back known for his explosive playing style, is confronting a significant challenge in his life as he battles amyotrophic lateral sclerosis (ALS), a progressive neurological disease. The 41-year-old athlete, who spent six celebrated seasons with the Tennessee Titans, was diagnosed with the condition around 17 months ago, a turn of events that has led him to reflect on his decade-long career in professional football.

In his peak season of 2009, Johnson earned the nickname “CJ2K” after he rushed for an astounding 2,006 yards, a feat that remains one of the high points of his career. During his time with the Titans, which commenced with his draft into the team in 2008, he was selected to the Pro Bowl three times and was named the NFL Offensive Player of the Year, alongside being a First-team All-Pro. After four additional seasons with the New York Jets and Arizona Cardinals, Johnson retired from professional football in 2018.

The gravity of his ALS diagnosis looms over Johnson, who has expressed a desire to raise awareness about the disease and its potential links to football. Utilising a speech-generating device that he operates with his eyes, Johnson has discussed the intersection of his sports career and his health challenges. He noted that while his doctors have not directly linked football to his condition, the conversation naturally arises due to his long-standing involvement in the sport.

“Football has come up throughout this process when we’ve talked with doctors because I played the game basically my whole life,” he shared. Johnson acknowledged the physical toll that years of rigorous play may have exerted on his body, though he is keen to approach the topic with caution. “Of course, you think about it,” he remarked, acknowledging the often brutal physical demands of the sport.
Despite his challenges, Johnson remains supportive of his 14-year-old twin sons, CJ and Kaden, who are following in their father’s athletic footsteps by playing football competitively. While he is fully aware of the risks associated with the sport, he emphasised his desire to educate them rather than discourage their passion for football. “I want them to understand the risks and take care of their bodies,” he stated. “If football’s what they love, and that’s the path they choose, I’m going to support them.”
Johnson’s wife, Brittany, echoed her husband’s sentiments, noting that as long as their sons enjoy the game, they should be allowed to pursue it—yet she, too, is concerned about the inherent risks involved. “It’s something that I think about, and it’s something that I worry about,” Brittany said. “But they’ve been so engulfed in it most of their lives that they don’t want to stop.”
As he navigates his diagnosis, Johnson is committed to using his platform to advocate for increased understanding and research into ALS and neurological diseases. He articulated the need for ongoing studies into the connections between football, repeated physical trauma, and the risk of neurological disorders. “The possible connection between football, repeated trauma and neurological diseases needs to continue to be studied so players and their families can have better answers,” he urged, highlighting an often-overlooked aspect of the sport.
Johnson’s story serves as both a reflection of a remarkable athletic career and a sobering reminder of the potential long-term repercussions of contact sports. As he continues to manage his condition, he hopes that sharing his journey will not only shed light on ALS but also inspire greater awareness and research into the safety and health of athletes at all levels.
Through his advocacy, Chris Johnson aims to honour his heritage as a professional football player while promoting the importance of health and safety in sport. As the NFL and its players navigate an evolving conversation about player safety, Johnson’s insights and experiences could pave the way for a more informed discussion on safeguarding the well-being of future generations of athletes.
