an unfortunate consequence of any sport
The punishment for a defensive player who commits a major foul. The offender is required to swim to the ejection area and remain there for 20 seconds, or until a goal is scored, or upon the signal of the defensive referee following a clear change of possession - whichever comes first. The ejected player also is awarded a personal fault. See major fouls and personal faults.
In sports, an ejection (or sending-off) is a disqualifying action assessed to a player or coach by a game official (such as a referee or umpire), usually for unsportsmanlike conduct.
