NWSL Teams Up with WSL in Project ACL to Tackle Female Soccer ACL Injuries
The National Women’s Soccer League (NWSL) has joined the English Women’s Super League (WSL) and the…
The National Women’s Soccer League (NWSL) is partnering with the Women’s Super League (WSL) and the global players’ union Fifpro in a three‑year research initiative, Project ACL, to cut the incidence of anterior cruciate ligament (ACL) injuries that affect women athletes 2‑6 times more often than men.Key DevelopmentsProject ACL expands the 2024 pilot that involved all 12 WSL clubs, 30+ players and academic partners such as Leeds Beckett University.The NWSL adds its 16 clubs to the study, bringing North American data into a global dataset.Players will use Fifpro’s workload‑monitoring tool to log training load, travel and recovery.Deputy executive director of the NWSL Players Association Tori Huster highlighted the need for player‑centric evidence.Fifpro director Alex Culvin notes that less than 10% of sports‑science research focuses on women.Data & Market ImpactWomen are 2‑6 times more likely to suffer ACL tears than men, with roughly 70% occurring in non‑contact situations.Injuries have sidelined marquee players (e.g., Leah Williamson, Vivianne Miedema, Sam Kerr), affecting team performance and broadcast ratings.Average recovery time ranges from 12 to 20 months, translating to lost salary and sponsorship value estimated at $1‑2 million per elite player.Why This MattersReducing ACL injuries will directly improve player health, extend careers, and protect the commercial value of women’s soccer. Clubs benefit from fewer roster disruptions, while broadcasters and sponsors retain star talent that drives viewership. The research also addresses a systemic gender gap—currently, under 10% of sports‑science funding targets professional women athletes—potentially reshaping funding priorities across the sport.Expert InsightThe high injury rate stems from a mix of biological factors (wider hips, quad‑dominant strength) and environmental conditions (artificial turf, male‑centric equipment, congested schedules). By aggregating data across two continents, Project ACL can isolate which external variables most amplify risk. The partnership also signals a strategic shift: leagues are investing in preventative science to avoid the costly downstream effects of long‑term injuries, mirroring concussion‑protocol models already in place.What Happens Next2026‑2027: Complete baseline surveys across all 16 NWSL clubs and integrate workload data into a unified analytics platform.2027‑2028: Publish the first set of evidence‑based injury‑prevention protocols, targeting training load, footwear design and pitch standards.2029 onward: Roll out league‑wide mandatory implementation, with periodic audits and potential certification for clubs that meet the new standards.
