Section 8: Safety Considerations
Concussion Protocol
NWSL operates under the league's Concussion Management Protocol developed in conjunction with U.S. Soccer and the league medical staff. The IFAB-trial concussion substitution permits one additional substitution per team beyond the five-substitute count when a player has an actual or suspected concussion. A player removed under the concussion protocol cannot return to the match and is subject to a graduated return-to-play assessment before being cleared for subsequent training and competition.
Heat and Air Quality
The league applies WBGT-based heat thresholds for cooling breaks and, in extreme cases, for delays of kickoff or postponement. Air-quality-index thresholds apply for venues affected by wildfire smoke or other particulate events, with on-field play decisions made in consultation with the league medical staff and the home club's medical team.
Field Conditions
The home club is responsible for ensuring the field of play meets league surface standards. Lightning detection and the league lightning policy halt outdoor activity within a defined radius of detected strikes; play resumes only after the all-clear interval has elapsed.
Athletic Training and Medical Coverage
- Each match must have at least one club physician on the bench, supported by certified athletic trainers
- An emergency action plan covering on-field cardiac, head/neck, and orthopedic emergencies must be in effect at every venue
- Independent league medical observers may be present for high-profile or postseason matches
Player Safety Innovations Carried From IFAB
- Concussion substitution remains in effect alongside the five-substitute allowance
- Goalkeeper 8-second hold rule (corner kick sanction) reduces stoppage-time stalling
- "Only The Captain" approach zone reduces mass-protest crowding around officials
- Goalkeeper tactical timeout crackdown reduces injury-feigning to advantage
Anti-Harassment, Anti-Discrimination, and Player Welfare
NWSL players, staff, and venue personnel are bound by the league's Anti-Harassment Policy, Non-Fraternization Policy, and Coach Code of Conduct, all available alongside the Competition Rules & Regulations on the league's Rules & Policies hub. The Fan Code of Conduct binds spectators and is enforced through venue operations.
