World Cup 2026 final pitch: how FIFA built a natural grass field over MetLife Stadium's artificial turf

When the 2026 FIFA World Cup final kicks off at MetLife Stadium in East Rutherford, New Jersey, the players will be running on a surface that took eight years to create. The stadium's permanent field is artificial turf, but FIFA rules require all World Cup matches to be played on natural grass. That single requirement forced organizers to build a temporary grass pitch from scratch on top of an synthetic surface designed for American football.

The final pitch is a warm-season blend made up of 95 percent Bermuda grass and 5 percent artificial turf, according to Sporting News. That artificial component is stitched into the grass for extra strength and uniformity, a process that took about three days to complete. Three other World Cup venues used a pre-stitched carpet that arrived with the turf already woven in.

Below the playing surface is a carefully engineered sandwich of layers. A geotextile base sits on top of aluminum flooring, which was added to block any feeling of the artificial turf beneath. Above that sits an impermeable layer to protect the synthetic surface below, then an 85-millimeter Permavoid drainage layer, irrigation lines, and 8 to 10 inches of sand. The grass and its root system sit on top. FIFA also requires sand root zones, vacuum ventilation, in-ground irrigation, hybrid reinforcement, and grow lights, Michigan State University reported.

The project was led by John Sorochan, a Canadian turfgrass scientist at the University of Tennessee at Knoxville. He was approached eight years ago by FIFA's Senior Pitch Management Manager Alan Ferguson to develop grass surfaces for all 16 tournament stadiums. The challenge was enormous: climates ranged from Vancouver to Mexico City, with some stadiums outdoors in full sun, others indoors without natural light, and one at roughly 7,000 feet of altitude.

Sorochan told the Calgary Herald that one of the biggest breakthroughs was learning how to grow grass into a plastic layer so the sod could be transported and installed without sending the plants into shock. That allowed the grass to recover quickly after being cut and moved. He also found that at least three inches of sand over a drainage layer was enough to hide the feel of concrete beneath, which mattered greatly for stadiums built on hard surfaces.

The pitch preparation included constant monitoring of moisture, firmness, and overall playability, according to the Associated Press. FIFA tested the surface during earlier matches at the stadium, including a Norway versus Senegal fixture that revealed how much water the surface could retain. Crews adjusted irrigation before games, at halftime, and during hydration breaks. A 13-day gap between the round of 16 match and the final was deliberately scheduled so the pitch could rest and recover.

For player safety and performance, organizers used a fLEX machine developed at the University of Tennessee to simulate a 170-pound player's foot striking the turf. The device tested wear, ball bounce, and whether the artificial surface below caused any unwanted reverberation. FIFA told the Associated Press that the goal throughout was a surface that met the highest standards for performance, consistency, and player safety.

Not everything was guaranteed. Last summer's Club World Cup gave crews only days to install a pitch, but for the World Cup itself FIFA booked the stadium for a full month of lead-in time. That extra buffer allowed for a proper irrigation and drainage system rather than grounds crews watering the field with hoses.
