Overview
- FIFA required natural grass at all 16 host venues for the 2026 World Cup, and several U.S. stadiums that normally use artificial turf installed temporary grass in mid-June 2026 to meet that rule.
- Players and the NFL Players Association highlighted the conversions as proof grass can be delivered and renewed a long-standing demand supported by an NFLPA survey showing 92 percent of players prefer grass.
- Team owners and league officials said permanent grass is costly and hard to maintain because it complicates concerts and tight event schedules and requires extra irrigation and staffing.
- Turf scientists at Michigan State and the University of Tennessee and FIFA-funded sod programs spent years developing transportable, high-quality sod systems that made the quick conversions possible, but experts say year-round upkeep remains the main obstacle.
- The visible switch has sharpened a labor question for future talks: players want grass included in bargaining while the league points to capital and scheduling trade-offs and the current collective bargaining agreement runs through 2031.
