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. Player-coaches may be head coaches or assistant coaches, and they may make changes to the squad and also play on the team.
Very few current major professional sports teams have head coaches who are also players, though it is common for senior players to take a role in managing more junior athletes. Historically, when professional sports had less money to pay players and coaches or managers, player-coaches were more common. Likewise, where player-coaches exist today, they are more common at, but not exclusive to, the lower levels where money is less available.
