A healthy scratch is a term used in sports, particularly in hockey and football, to refer to a player who is physically healthy but is not dressed in uniform for a game. The coach or team manager decides not to use the player for various reasons, such as lack of self-discipline, poor performance, or tactical reasons. It is not an official term with rules, but rather a decision made by the team. A healthy scratch can also refer to a player who is not on the teams roster, is inactive for disciplinary reasons, or is injured.
