Overview
- Following the 2026 World Cup conversions of seven NFL stadiums to natural grass, the NFL Players Association and high-profile players have stepped up public pressure for permanent grass, pointing to an NFLPA survey saying 92 percent of players prefer grass.
- The NFL and field director Nick Pappas say recent season-level injury data from 2021 and 2025 do not show a clear, statistically significant difference in overall injury rates between turf and grass.
- Players and union advocates cite older NFL data from 2012–2018 that found higher rates of certain non-contact lower-body injuries on turf — for example a 28 percent higher chance of non-contact lower-extremity injuries — and say that history informs their safety demand.
- Team owners and stadium operators argue the World Cup installs prove short-term feasibility but not long-term practicality, pointing to upfront conversion costs, ongoing maintenance and the need to host concerts and other events as barriers to leaguewide change.
- With the NFL publishing approved field standards but declining to require grass, the dispute is moving toward collective bargaining or individual owner choices, and could affect player safety policy, stadium budgets and future negotiations.
