Based on two years of fieldwork and over 100 interviews, we analyze mixed martial arts fighters' fears, how they managed them, and how they adopted intimidating personas to evoke fear in opponents. We conceptualize this process as ''managing emotional manhood,'' which refers to emotion management that signifies, in the dramaturgical sense, masculine selves. Our study aims to deepen our understanding of how men's emotion work is gendered and, more generally, to bring together two lines of research: studies of gendered emotion management and studies of emotional identity work. We further propose that managing emotional manhood is a dynamic and trans-situational process that can be explored in diverse settings.While fighters in the locker room prepared for combat in the cage, two men from the previous fight staggered in. Juan 1 -the victor-had shiny contusions under both eyes and made it to a folding chair where he sat staring into space. As two paramedics tried to keep him conscious, he cracked a smile with swollen lips and tried unsuccessfully to communicate meaningfully. As the paramedics carried Juan off on a stretcher, Mikehis opponent-leaned against a wall and talked with his trainer. As blood flowed from his nose and mouth, Mike began to sob. His trainer handed him a towel, which he brought to his face with shaking hands. When asked if he was upset about Juan, he pulled away the bloodied towel and said, ''I don't like losing.'' Juan and Mike's post-fight experiences highlight what competitors of mixed martial arts (MMA) most often say they fear: injury and losing. Competitions generally occur in a locked cage and fighters wear thin, open-fingered gloves and are allowed to punch, kick, wrestle, and use martial arts techniques. Fights are broken into rounds and end when one fighter submits
