XFL The XFL was a professional American football league which played one season in 2001. It was operated as a joint venture between the World Wrestling Federation (WWF, now known as WWE) and NBC. The XFL was conceived as an outdoor football league that would take place during the NFL off-season, and promoted as having fewer rules and encouraging rougher play than other major leagues. The league had eight teams in two divisions, including major markets and those not directly served by the NFL, including Birmingham, Las Vegas, Los Angeles, Memphis, and Orlando. The XFL operated as a single entity, with all teams centrally owned by the league.

The Orange Tornadoes relocated to Newark and the Buffalo Bisons and the Boston Bulldogs dropped out. The Portsmouth Spartans entered as a new team.
