farm team

In sports, a farm team is generally a team or club whose role is to provide experience and training for young players, with an agreement that any successful players can move on to a higher level at a given point, usually in an association with a major-level parent team. This system can be implemented in many ways, both formally and informally. It is not to be confused with a practice squad, which fulfills a similar developmental purpose but the players on the practice squad are members of the parent team.
