Practice squad

In gridiron football, the practice squad, also called the taxi squad or practice roster, is a group of players signed by a team but not part of their main roster. They serve as extra players during the team's practices, often as part of the scout team by emulating an upcoming opponent's play style. Because the players on the practice squad are familiar with the team's plays and formations, the practice squad serves as a way to develop inexperienced players for promotion to the main roster.
