If a substitute enters the court without reporting to the scorer; and without being beckoned by an official, except between periods, then a technical foul shall be charged to the substitute. Each illegal substitute gets one technical foul per instance, whether they didn’t report, or entered the court without being beckoned, or both. However, two technical fouls are not charged if the illegal substitute doesn’t report and enters without being beckoned. A substitute technical foul is charged if recognized by an official before the ball becomes live following the first dead ball. Once the ball becomes live, the substitute is a legal player at that point, the foul is not penalized. Remember, the ball becomes live when: on a jump ball, the tossed ball leaves the referee’s hand; on a throw-in, it is at the disposal of the thrower; and on a free throw, it is at the disposal of the free thrower.
