Examining former athletes’ health-related beliefs and behaviors on the long-term effects of concussions and potentially developing chronic traumatic encephalopathy (CTE) offers a domain to understand how men renegotiate their masculinities. In this paper, we explore how the cultural production of the concussion crisis shapes the ways in which men athletes make sense of self and their masculinity in the face of declining health. Drawing on in-depth interviews with 27 male, former athletes, this article examines the multiple ways in which gender shapes their experience and treatment of traumatic brain injuries or suspected CTE. We show how men are re-negotiating their aging masculinities through illness narratives and how the cultural production of the concussion crisis in sports shapes these narratives. We break down our analysis into three sections: (1) reflections of chaos narratives and stories of never-aging masculinities, (2) the ways the concussion crisis shapes their restitution narratives, and (3) quest narratives combining never-aging and aging masculinities. Whether or not these athletes have or are treated for CTE, we argue that they reformulate their masculinity to regain control over their manhood and to feel a sense of relief.
