Overview
- Several NFL stadiums that normally use artificial turf will be fitted with temporary natural grass for the 2026 FIFA World Cup and are expected to revert to turf after the tournament.
- San Francisco 49ers pass rusher Nick Bosa publicly criticized the plan as "a little bizarre" during a team media session, bringing fresh attention to the issue.
- Research cited in coverage found non-contact knee injuries were 32% higher and non-contact foot and ankle injuries were 69% higher on turf than on grass in a 2012–2018 study.
- Team owners and stadium operators say permanent grass is costly and fragile, and that turf offers greater durability for concerts, multiple sporting events, and weather swings.
- The temporary conversions and player backlash increase leverage for the NFLPA and could shape future bargaining talks over playing surfaces and safety rules.
