The NFL and TMRW Sports released the first renderings of the venue for their flag football league. Bret McCormick of Sports Business Journal reported the images on July 9, 2026.
A Venue That Moves Between Cities
The renderings show a modular stadium. Crews can assemble the structure, take it apart, and move it to a new city. The design lets the league play in one market for the first season and add cities later.
The images show a three-level stadium with an open roof. A second flag field sits next to the main field for public use. The plans also include a building for merchandise or a bar and restaurant, plus a stage that faces the seats.
The NFL is using the renderings in pitches and requests for proposals. The league is sending them to host cities and architecture firms. The NFL has not released the seating capacity or the construction cost.
Two Leagues Ahead of the 2028 Olympics
The plan covers a men's league and a women's league. The NFL is timing the launch to the run-up to the 2028 Los Angeles Olympics, where flag football joins the Games for the first time.
TMRW Sports runs the league operation. Mike McCarley, Rory McIlroy, and Tiger Woods co-founded the company, which also runs the TGL golf league.
The Money and the Backers
The NFL has committed about $160 million to its flag football push. The investor group includes all 32 NFL teams through 32 Equity. Backers include Tom Brady, Peyton Manning, Joe Montana, Larry Fitzgerald, Russell Wilson, Billie Jean King, Serena Williams, and Alex Morgan.
Larry Fitzgerald told ESPN the league had been in the works for two years.
Where the UFL Fits
The flag football league gives the NFL a second property outside its fall season. The UFL, the spring pro league, already fills that window. The UFL runs as the NFL's developmental league.
The UFL feeds players to the NFL. After the 2026 season, 22 UFL players signed with NFL teams. That group included Antwane Wells to the Falcons, Denzel Mims to the Cowboys, and Hakeem Butler to the Broncos.
The UFL drew 10,632 fans per home game across eight teams in 2026. St. Louis led at 23,238 per game. Regular-season ratings rose 8% on Disney networks and 5% on Fox from 2025. A Louisville-Columbus game reached 1.59 million viewers on Fox.
The NFL committed about $160 million to flag football. The UFL runs as a separate operation under co-owner Mike Repole and its ownership group. Both leagues compete for football fans in the months between NFL seasons. Repole said the UFL has an 80% chance of keeping all eight current markets and plans to add Oklahoma City in 2028.
Flag Football Growth
Youth flag football reached about 4.1 million players in the United States by 2026. That count is up more than 50% since 2020. High schools offer the sport in 39 states.
Brady played in the Fanatics Flag Football Classic in March 2026 with Joe Burrow, Jayden Daniels, and Jalen Hurts. Brady suggested a change to the format: "I think maybe about different ways to marry a 7-on-7 version of the game versus a flag version where it resembles a little bit more football."
