Knoxville, Tennessee – From exhilarating goals to devastating defeats, the FIFA World Cup captivates its audience.

Next year, the 2026 FIFA World Cup will commence, co-hosted by the US, Canada, and Mexico, marking a historic event.

This tournament may feature superstars like Lionel Messi and Cristiano Ronaldo, and is the first occasion where three nations co-host in 16 cities, making it the most complex World Cup ever, as per FIFA.

“No matter if they’re in Seattle or playing in Guadalajara, I need these pitches to perform consistently. I want the same bounce and the same player-to-grass interaction,” said an expert.

“Safety is paramount and must be my top priority,” Ferguson stated during an interview at the University of Tennessee facility in Knoxville, where researchers collaborate with Michigan State to help FIFA evaluate each venue’s pitch preparations for the tournament.

“Players need to feel confident as they make quick directional changes; the ground must be stable,” he added.

Managing over 12 venues for NFL games and concerts full of monster trucks is no small feat.

The U.S. venues could face increased scrutiny after last summer’s Copa America Tournament raised concerns, notably from players like Argentine goalkeeper Emiliano Martinez, who referred to conditions at Atlanta’s Mercedes-Benz Stadium as a “disaster.”

“There’s no doubt that last year’s tournament raised the stakes,” Ferguson remarked, referencing the tournament that featured the best 16 teams from North, Central, and South America, as well as the Caribbean.

“Research was in progress, but Copa highlighted more traditional hesitations regarding international football pitches. Venue schedules are packed with events transitioning from one to another continuously.”

U.S. stadiums have long been central to the debate on natural versus artificial turf in terms of safety. Next summer, all venues will adopt artificial stitch blends of natural grass, focusing on both the underlying structure and the grass itself.

In April, NBC News had exclusive access to the Knoxville facility, where researchers led by Professor John Solochan are tackling these challenges.

The team is investigating artificial stitches and layering techniques beneath the grass to improve root growth and ensure light use, contributing to consistent pitch quality indoors and outdoors.

Solochan, who specializes in turfgrass science and management, mentioned that the mix for warm-season venues includes Bermudagrass, while cool-season venues use a blend of perennial rye and Kentucky bluegrass. Indoor venues also benefit from recommended drainage layers, contributing to a firmer pitch.

“Many of these trials here were unsuccessful,” Solochan explained as he showcased a grid filled with grass plots labeled with different variables. Some experiments involved sewing fibers together to fortify the play surface, while others examined the upper layers typical in World Cup venues featuring flooring for concerts and artificial turf.

The facility includes setups that simulate indoor stadium growth conditions, along with a flex machine that tests the impact on players’ ankles by pressing soccer shoes into the grass. The initial data shows promising insights.

“You can track the speed of the ball as it moves. By analyzing the footage, we can determine its recovery speed, angle, and exit coefficients,” Solochan noted while standing next to a machine resembling one used for NFL punt returns.

Ferguson concluded, “It’s the science that underpins the game. That’s what elevates the sport.”
