Eleven NFL stadiums are currently mid-identity crisis — ripping out artificial turf, importing grass from Colorado, and dismantling corner seats to make room for a sport that most of their usual tenants have never played. The 2026 FIFA World Cup kicks off June 11, and the transformation underway across the United States is more involved than most people realize.
This isn't just rolling out a new surface. Dallas's AT&T Stadium raised its entire playing field by four feet — 15,000 tons of material — and reportedly spent close to $300 million on renovations. Boston's Gillette Stadium dug down 10 inches to unearth irrigation systems that hadn't been touched since the early 2000s. Seattle's Lumen Field deployed nearly a foot of sand on top of existing artificial turf before any grass was laid. These are construction projects, not groundskeeping jobs.
Grass, grow lights, and the Colorado connection
FIFA mandates natural grass. That single requirement is the root cause of almost every major renovation across the 11 venues. For indoor and semi-indoor stadiums — Dallas, Houston, Atlanta, Los Angeles, Boston — that means trucking in ryegrass-Kentucky bluegrass blends from Colorado, installing specialty pink grow lights to compensate for limited sunlight, and setting up full water management systems layered beneath the surface.
Houston's setup offers the clearest picture of the scale involved. Grass arrives on refrigerated trucks in rolls up to 50 feet long, each weighing between 1,800 and 2,000 pounds. A specialty unrolling machine handles each unit. Once laid and stitched with polypropylene fibers, eight full-time staff will maintain the field non-stop from installation through July 5. All in, Houston spent an estimated $15 million.
Not every stadium needed that kind of overhaul. Miami's Hard Rock Stadium is the only U.S. professional sports venue with its own sod farm, so the Dolphins are essentially supplying their own Bermuda grass. San Francisco's Levi's Stadium already plays on Bermuda and put $200 million into broader renovations over the past two years — drainage, irrigation, and ventilation improvements built into that spend. Philadelphia's Lincoln Financial Field already had natural grass and kept renovation costs minimal, though rows of corner seats still had to go.

- Boston Stadium (Gillette Stadium): Turf removed, 10 inches of gravel excavated, legacy irrigation systems uncovered and reactivated, ryegrass-Kentucky bluegrass installed over six weeks. Hosts a quarterfinal.
- Dallas Stadium (AT&T Stadium): Field raised four feet using 15,000 tons of material, lower-level seats removed, Colorado grass installed under 18 pink grow lights. ~$300 million total renovation. Hosts a semifinal and Argentina group stage matches.
- Houston Stadium (NRG Stadium): Colorado ryegrass-Kentucky bluegrass on refrigerated trucks, polypropylene fiber stitching, eight dedicated grounds staff through the tournament. $15 million estimated cost. Corner seats removed.
- Kansas City Stadium (Arrowhead Stadium): Resodded with Bermuda grass, underground air system installed, 3,500 modular seats removed. Renovations underway since 2024. Hosts a quarterfinal.
- Los Angeles Stadium (SoFi Stadium): Washington-sourced ryegrass-Kentucky bluegrass, multi-layer water management system two feet above NFL surface, grow lights, up to 30 grounds staff needed. 400 corner seats removed. Hosts USMNT opener and a quarterfinal.
- Miami Stadium (Hard Rock Stadium): Own Bermuda sod farm used, three-day planting process, artificial fiber stitching. No significant lower bowl construction needed. Must transition from F1's Miami Grand Prix in May. Hosts the third-place match.
- New York New Jersey Stadium (MetLife Stadium): Bermuda grass (heat-suited for summer), 600 rolls laid over sand and ventilation layers. 1,740 corner seats removed. Hosts the July 19 final.
- Philadelphia Stadium (Lincoln Financial Field): Natural grass already in place, mowed to exactly 22mm. Corner seat rows removed. Minimal renovation costs. Hosts a round of 16.
- San Francisco Bay Area Stadium (Levi's Stadium): Bermuda grass with $200 million renovation covering drainage, irrigation, and ventilation. Modular corner seats removed. Also hosting Super Bowl 2026.
- Seattle Stadium (Lumen Field): $19.4 million investment covering field, infrastructure, security, and transport. Near a foot of sand deployed over artificial turf, ryegrass-Kentucky bluegrass installed in March. Northern bleacher benches replaced with backed seating per FIFA rules — those seats stay after the tournament. Hosts USMNT group stage match.
What the final host gets right
MetLife Stadium in New Jersey draws the July 19 final, and the prep reflects that. Bermuda grass — the right call for a summer outdoor venue — laid across 600 rolls with full sand and ventilation infrastructure underneath. 1,740 seats removed from the corners to fit the wider FIFA-regulation pitch. The stadium that hosts Brazil, France, Norway, and England in the group stage will look nothing like the home of the Giants and Jets by the time Messi, Mbappé, or Ronaldo walks out for the biggest game of the tournament.
The size difference alone tells you how significant the conversion is. An NFL field runs 120 yards by 53.3 yards. A FIFA-regulation pitch is 114.8 yards by 74.4 yards — nearly 40% wider. Every stadium with a lower bowl tight to the sidelines has had to remove seats, raise surfaces, or both just to fit the playing area. That's before the grass, the lighting, the irrigation, and the 2,000 covered-up sponsor logos.
For the venues hosting deep knockout rounds — Dallas, Atlanta, New Jersey — this is a nine-figure commitment for a tournament that lasts roughly six weeks. Whether the pitches hold up under the summer heat and the weight of a World Cup will be the real test. The groundskeeping crews won't get much sleep finding out.
