Team 9

Team 9 was a specialized team that acted as a hybrid farm team and practice squad for the league, and was inspired by a similar scheme employed by NFL Europe. It held a maximum of 40 players at a time and was meant to prepare players for call up to one of the XFL's 8 teams to fill roster vacancies due to injuries of other players or if the teams see a player as a "hidden gem". The team shares practice facilities and support staff with the Dallas Renegades but maintained its own coaching staff; its head coach was Bart Andrus and was assisted by Pete Kuharchek and Peter Vaas.

During the first two weeks of the season, teams were encouraged to use players from Team 9 to fill roster spots, but are not required to do so, as they would prefer to sign a player unaffiliated with the XFL or re-sign a player who participated in their preseason camps but was cut. After Week 2, exclusively using Team 9 players to fill rosters became a requirement, with Team 9 constantly replenishing itself by adding new players from outside the XFL.

After Week 5, all 40 players on Team 9 were dispersed to the XFL's 8 teams and each team's maximum roster size increased from 52 to 57 players but the season ended abruptly. After the Week 5 roster spot increase, it reloaded to approximately 36 players. Team 9 didn't not include the specialist positions of kicker, punter, or long snapper.
