Harrison Browne, a forward for the Buffalo Beauts of the National Women’s Hockey League, has publicly announced he is transgender, becoming the first athlete in professional team sports to do so as an active player.
Browne, who formerly identified as Hailey Browne, is now listed as Harrison Browne on the NWHL website. According to an NWHL official, he has informed the League that he won’t undergo gender reassignment surgery until after retiring as a pro hockey player. He will also not take any testosterone supplements while playing because it violates performance-enhancing drug policies for the League.
