Substitution
The replacement of one active player with a teammate from the bench during a match, carried out under each sport's specific procedures and limits.
Definition
A substitution is the sanctioned exchange of an on-field or on-court player for a teammate who has been waiting to play, governed by rules covering when it may happen, how it is reported to officials, and how many are allowed. Coaches use substitutions to rest tired players, change tactics, respond to injuries, or protect a player who is carrying a disciplinary caution.
The rules vary widely between sports. Football (soccer) traditionally allows a small fixed number of permanent substitutions, so a replaced player cannot return, whereas basketball, volleyball, and ice hockey permit frequent changes, some of them 'rolling' so a player may re-enter. Many competitions also restrict the moment of change to a dead-ball stoppage, while others allow it 'on the fly' during live play.
