Beckoned ???
 

Penalized if discovered before the ball becomes live: A substitute shall not enter the court without reporting to the scorer; and without being beckoned by an official, except between periods. Substitute technical foul. A maximum of one foul for either, or both, requirements, reporting, and/or 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.
