Ex-NFL Star Larry Johnson Reveals Memory Loss and Brain Health Fears After Football Career

Larry Johnson, once one of the NFL’s most feared running backs, is speaking out about the cognitive toll of his football career. The 46-year-old former Kansas City Chiefs All-Pro, who retired in 2011 after seven seasons, says he can barely recall his playing days—only up to around 2006 or 2007. Johnson describes struggling with memory loss and intrusive thoughts, raising concerns about the long-term impact of repeated head trauma. His story adds to the growing conversation about brain health in football, particularly among former players facing symptoms consistent with chronic traumatic encephalopathy (CTE). Johnson’s willingness to share his struggles highlights the urgent need for better support and research into football-related brain injuries. As more retired players come forward, the league faces increasing pressure to address player safety and post-career health.
