The NWSL and NWSLPA are teaming up with Project ACL, a research initiative focused on reducing ACL injuries in pro women’s soccer.
Launched in 2024 by England’s WSL, the US investment represents a coordinated approach between two of the world’s top pro leagues to address the environmental and biological factors behind the epidemic.
Along with FIFPRO, Nike, and Leeds Beckett University, the partnership is spearheading a three-year study slated for June 2026, with researchers tracking players’ travel schedules, workload, and game minutes — especially when playing on short rest.
ACL tears are two to six times more likely to occur in women’s soccer athletes than men’s. Yet according to Project ACL, just 8% of all sports research specifically targets women’s athletes.
Chelsea and Australia striker Sam Kerr, US and Gotham defender Tierna Davidson, and England and Arsenal center-back Leah Williamson represent a fraction of high-profile ACL injuries sustained in recent years.
“We believe that player-centricity and collaboration with key stakeholders are central to establishing meaningful change,” said Dr. Alex Culvin, director of women’s football at FIFPRO. “Players, competition organizers, and stakeholders around the world will benefit from Project ACL’s outputs and outcomes.”
