San Francisco 49ers tight end George Kittle says the grass surfaces used for the World Cup demonstrate that NFL teams could play on natural grass if league owners prioritized it. In comments reported by multiple outlets, Kittle contrasts the attention paid to field conditions for soccer tournaments with the typical reliance on artificial turf at many NFL stadiums. He points to the fact that several NFL venues that host football on artificial surfaces install or use grass for soccer matches during major events, including World Cup-related fixtures. Kittle argues that the practical ability to provide grass fields during those events suggests NFL games could also be played on natural grass if owners were willing to cover the additional costs and operational changes. The reports frame his remarks as a question of investment and priorities rather than as a complaint about a specific game. The underlying theme across coverage is that players notice differences between turf types and that hosting requirements for other sports have led to real grass being used in environments otherwise dominated by synthetic playing surfaces.
