Substitutions are generally made to replace a player who has become tired or injured, or who is performing poorly, or for tactical reasons (such as bringing a striker on in place of a defender). Unlike some sports (such as American football or ice hockey), a player who has been substituted during a match may take no further part in it . </P> <P> Most competitions only allow each team to make a maximum of three substitutions during a game, although more substitutions are often permitted in non-competitive fixtures such as friendlies . Allowing a fourth substitution in extra time is currently being trialed at several tournaments, including the 2016 Summer Olympic Games, the 2017 FIFA Confederations Cup and the 2017 CONCACAF Gold Cup final . Each team nominates a number of players (typically between five and seven, depending on the competition) who may be used as substitutes; these players typically sit in the technical area with the coaches, and are said to be "on the bench". When the substitute enters the field of play it is said they have come on or have been brought on, while the player they are substituting is coming off or being brought off . </P>
