The USFL returns in 2022, with all games likely to be held in Birmingham Alabama for the first season.  Unfortunately, no Washington Federals.  Fox Sports owns the league and will broadcast the games.

The teams:

North Division
Michigan Panthers
New Jersey Generals
Philadelphia Stars
Pittsburgh Maulers

South Division
Birmingham Stallions
Houston Gamblers
New Orleans Breakers
Tampa Bay Bandits

Teams will play a ten game schedule, playing in their division twice against each team, and once against teams in the other division.  Games start in April

With the XFL also relaunching, I wonder if there's enough interest to support two spring leagues.

 Good question. Makes sense there’s no DC team if there can be a return of the XFL one
