ACL Injury Surge Threatens 2026 NWSL Season
8/19/2026, 3:00:56 AM
Core Event
The 2026 NWSL season has seen an unprecedented wave of season-ending ACL injuries. High-profile players such as Portland Thorns forward Olivia Moultrie, Chicago Stars forward Jordyn Huitema, and San Diego Wave midfielder Jun Endo have been ruled out after tearing their ACLs. The league has accelerated research and prevention through the newly launched Project ACL.
Background & Context
ACL injuries have long plagued women’s soccer. A 2023 AP report noted elite players—including Vivianne Miedema, Leah Williamson, Beth Mead, Janine Beckie and Alexia Putellas—missed major tournaments because of knee injuries. Studies cited by Dr. Mark Cullen of the University of New Hampshire show women are up to eight times more likely than men to suffer ACL tears in sports that require rapid direction changes. Contributing factors include anatomical differences and gaps in training resources such as warm-up routines, core-strength work, landing drills and menstrual-cycle monitoring.
Data & Statistics
- 18 NWSL players have suffered season-ending knee injuries so far in 2026, according to Spotrac analyst Taylor Vincent.
- Olivia Moultrie had 5 goals before her injury.
- The tally includes at least 3 additional ACL tears (Huitema, Endo, and an unnamed player).
- Women’s ACL injury rates are 8 × higher than men’s in comparable sports.
Key Figures & Groups
- Olivia Moultrie – Forward, Portland Thorns FC.
- Jordyn Huitema – Forward, Chicago Stars.
- Jun Endo – Midfielder, San Diego Wave.
- Taylor Vincent – Analyst, Spotrac.
- Dr. Mark Cullen – Orthopedic specialist, University of New Hampshire.
- Sarah Gregorius – NWSL vice-president of Sporting, leads Project ACL.
Official Statements & Responses
The NWSL, in partnership with the Players Association, FIFPRO and the English Women’s Super League, launched Project ACL to investigate physical causes and professional environments that contribute to injuries. Dr. Cullen emphasized the need for targeted strength and conditioning programs and individualized menstrual-cycle monitoring to reduce fatigue-related risk.
Why It Matters
The concentration of ACL injuries threatens competitive balance, player development and marketability. Losing marquee players reduces on-field talent and can affect national-team selections, as Moultrie’s absence may jeopardize her participation in upcoming U.S. Women’s National Team World Cup qualifiers. The surge highlights gender-specific health challenges and prompts calls for systemic changes in training and medical support.
What’s Next
Project ACL will continue data collection throughout the 2026 season, collaborating with UNC-Chapel Hill’s Kang Women’s Institute to study menstrual-cycle impacts. Findings are expected to shape league-wide guidelines on workload management, conditioning standards and injury-prevention strategies. The NWSL has pledged ongoing investment in research and player-safety initiatives to reduce future ACL occurrences.
