In basketball, disqualification is a penalty for certain offenses during the game. If a player is disqualified during a game, the player must leave the court. If a player is disqualified before the game, he or she is also restricted from attending the game and sitting on the sideline. A player may be disqualified as a result of reaching the foul limit, committing a dangerous foul on another player, or some other league offense. If a player is ineligible to play for any reason, he or she may be disqualified for play for one or more games. A disqualification is not viewed in a favorable light and is avoided when possible.
A disqualification is similar to an ejection in that both result in a player being removed from the court. However, they are different in that an ejection is made as a result of a specific action during the game, while a disqualification is usually the result of multiple actions. The example above of acquiring fouls is a good example of disqualification after repeated actions. An ejection may occur, for example, after a player attempts to fight another player. A disqualification, while still negative, is less so than an ejection. At the professional level, an ejection will often be matched with a fine, whereas a disqualification will not be.
