(NEXSTAR) – U.S. hockey star Haley Winn is competing in her debut Olympic Games in Milan as one of 61 players from the Professional Women's Hockey League represented in the 2026 tournament. Winn, a member of the Boston Fleet, is among a large group of league athletes appearing on several national rosters. The Professional Women's Hockey League is currently in its third season. Its influence is most prominent on the Canadian team, which is made up entirely of league players, while the U.S. roster consists of approximately 70% league athletes. Winn's brothers, who all play college hockey, traveled to Milan to support her Olympic debut. They have gained social media attention for their game day outfits and videos documenting their experience. "We all played college hockey ... she's just better than us," one of the brothers told Nexstar. The brothers say their mission is not only to support their sister, but to highlight the skill and explosiveness of the U.S. women's hockey team. Beyond the United States and Canadian rosters, several other national teams in the 2026 Games feature players from the league. These countries include Czechia, Finland, Germany, Sweden, Switzerland and Italy. The Professional Women's Hockey League is managed by a leadership group that includes Jayna Hefford, a four-time Olympic hockey gold medalist and Amy Scheer, a decades-long sports executive. "We have a group of players that have done a lot of work to get to this point and build this league and then a bunch of passionate people that are leading it at the league," Hefford said. "And so it's been amazing to see the growth and the success over the first few seasons." The USA women will face Canada in the gold medal game Thursday at 1:10 p.m. ET.
