The National Women's Soccer League (NWSLPA) and the global players union, FIFPRO, have joined Project ACL, a global initiative aimed at reducing the number of anterior cruciate ligament injuries in professional women's football. The initiative aims to better understand the multiple factors behind these injuries and establish evidence-based practices for the women's game. Since its launch, Project ACL researchers have surveyed staff across all 12 WSL clubs and conducted interviews with over 30 players. The project is also tracking players' workload, travel and critical zone appearances via the FIFPro Player Workload Monitoring tool.
