Seven NFL stadiums that use artificial turf during the NFL season are installing natural grass for the 2026 FIFA World Cup. Many players and fans have questioned why those same venues cannot use grass during the NFL season.

According to Pro Football Doc, the answer is more complicated than simply choosing between grass and turf.

Why Stadium Design Matters

According to Pro Football Doc, many NFL stadiums were never designed to support permanent natural grass.

Some venues, including those in Arizona and Las Vegas, were specifically engineered with retractable grass systems that allow the surface to be moved outdoors for maintenance and sunlight.

Most NFL stadiums do not have that capability.

“You can't simply retrofit a stadium like MetLife and make it function the same way,” Pro Football Doc said.

World Cup Matches and NFL Seasons Are Not the Same

Pro Football Doc explained that installing grass for a short World Cup tournament is very different from maintaining a natural grass field throughout an NFL season.

World Cup matches take place during the summer and involve a limited number of games. Soccer players are generally lighter, the action is spread across the field, and wear patterns are less concentrated.

NFL football creates significantly more stress on a playing surface.

According to Pro Football Doc, repeated collisions involving 300-pound linemen place constant pressure on the same areas of the field, particularly between the hash marks, over a season that extends into late fall and winter.

Financial and Operational Challenges

Another factor is how modern stadiums are used.

Many NFL venues host concerts, college football games, high school championships, charity events and other non-NFL activities throughout the year.

Pro Football Doc noted that artificial turf allows stadium operators to accommodate those events more easily. Natural grass can be damaged quickly and requires substantially more maintenance.

Pro Football Doc Analysis

While Pro Football Doc believes high-quality grass is generally safer than turf, he cautions against assuming all grass fields are automatically better.

"The key is well-maintained grass," he said.

Poor grass conditions can create their own injury risks through uneven footing, divots, ruts and inconsistent traction. Players slipping on unstable surfaces or getting cleats caught in damaged sections of the field can also lead to injuries.

According to Pro Football Doc, surface quality and consistency are just as important as the material itself.

Bottom Line

Pro Football Doc believes players would generally prefer a high-quality natural grass field over turf.

However, installing grass for a handful of World Cup matches is much different than maintaining it through an entire NFL season. Stadium design, weather, field durability and year-round stadium operations all create challenges that make a league-wide transition to grass more complicated than many fans realize.

The biggest takeaway from Pro Football Doc is that the debate should not simply be grass versus turf. The real issue is whether the playing surface, regardless of material, is safe, consistent, and properly maintained.
