A player-coach (also playing coach, captain-coach, or player-manager) is a member of a sports team who simultaneously holds both playing and coaching duties. The term can be used to refer to both players who serve as head coaches and as assistant coaches. He or she makes changes to the squad and plays as well.Very few current major professional sports teams have head coaches who are also players, though it is extremely common for senior players to take a role in managing more junior athletes.
