Launched in 2024, the research project recently welcomed two US-based organisations: the National Women’s Soccer League Players Association (NWSLPA) and National Women’s Soccer League (NWSL).
About Project ACL
Led by FIFPRO, PFA England, Nike and Leeds Beckett University, Project ACL aims to research ACL injuries and understand more about multifactorial risk factors.
After piloting in England’s Women’s Super League (WSL), Project ACL will expand to the NWSL in the US, reflecting the global importance of the project’s research and outcome.
“We are incredibly excited to bring the NWSLPA and NWSL to Project ACL,” said Director of Women’s Football at FIFPRO, Dr. Alex Culvin, via official press release.
“Overall, we believe that player-centricity and collaboration with key stakeholders are central to establishing meaningful change in the soccer ecosystem and that players, competition organisers and stakeholdersaround the world will benefit from Project ACL’s outputs and outcomes.”
Interviews with over 30 players and team surveys across all 12 WSL clubs provided the project’s research team with valuable information about current prevention strategies and available resources.
Furthermore, the project tracks player workload and busy schedule periods during the season through the FIFPRO Player Workload Monitoring tool, therefore gaining insights into the link between scheduling and injury risks.
Looking to the data
Project ACL’s partnerships with the WSL – and now the NWSL – are immensely valuable for the future of player welfare in women’s football.
Although ACL injuries affect both male and female athletes, they are twice as likely to occur in women than men. However, according to the NWSL, as little as 8% of sports science research focuses on female athletes.
In Australia, several CommBank Matildas suffered ACL injuries in recent years: Sam Kerr was sidelined from January 2024 to September 2025, Ellie Carpenter for 8 months after suffering the injury while playing for Olympique Lyonnais, and Holly McNamara came back from three ACL’s aged 15, 18 and 20.
And this is just the tip of the iceberg. The 2025/26 ALW season saw several ACL incidents, including four in just two weeks.
Research, prevent, protect
Injury prevention and research are vital to sport – whether professional or amateur.
But when the numbers are so shocking – and incidents are so common – governing bodies must remember that player welfare comes above all else. Research can inform prevention strategies. Prevention means players can enjoy the game they love.
The work of Project ACL, continuing until 2027, will hopefully protect countless players across women’s football from suffering long-term or recurring injuries.
