NFL stadiums swapped turf for grass ahead of 2026 World Cup. George Kittle thumping for permanent change: 'Clearly, we know it's possible'

Key Points:

• George Kittle highlighted the superior grass surface at SoFi Stadium during the 2026 World Cup and questioned why the NFL couldn't have similar grass fields all season, sparking renewed debate on turf versus grass in the NFL.
• Of the 11 NFL stadiums hosting World Cup games, seven typically use synthetic turf but temporarily installed natural grass for the tournament, while only four stadiums already use natural grass, with FIFA providing the grass surfaces.
• NFL players overwhelmingly prefer grass fields due to better injury outcomes and comfort, with 92% favoring grass according to an NFLPA survey, but the NFL cites injury data showing some risks with grass and emphasizes the need for high-quality surfaces.
• The turf versus grass debate is complicated by business considerations, as turf allows stadiums to host multiple events year-round, reducing maintenance costs, whereas grass fields require more upkeep and limit stadium usage.
• Former players and coaches, including Jason Garrett and Devin McCourty, criticize NFL owners for prioritizing profits over player health by favoring turf, noting the irony of grass fields being installed temporarily for the World Cup while NFL players must regularly play on turf.
