2.13 Fall
Any part of both shoulders or part of both scapulae (For pinning area, see Illustration No� 2�) of either wrestler held in contact with the mat for one second constitutes a fall� The one-second count (one-thousand-one) shall be a silent count by the referee and shall start only after the referee is in position to observe that a fall is imminent, after which the shoulders or scapulae area must be held in continuous contact with the mat for one second before a fall is awarded�
2�13�1 Awarding a Fall at Edge of Wrestling Area. When awarding a fall at the edge of the wrestling area, a fall may be awarded when any part of either wrestler is in bounds� (See Rule 2�4 and Illustration Nos� 59 and 60�)
2�13�2 No Fall. If any portion of the body of one of the wrestlers is out of bounds so that either wrestler is disadvantaged, no fall shall be awarded and out of bounds shall be declared�
2�13�3 Out of Bounds� When the match is stopped for out of bounds in a fall situation, the match shall be resumed in the starting position on the mat with the offensive wrestler in the advantage position� (For exception, see Rule 2�1�5�)
2�13�4 Indicating the Fall. As soon as the criteria listed in the first part of this section are met, the referee shall indicate the fall by striking the mat with the palm of the hand and blowing the whistle�
2�13�5 Fall—End of Period� When the referee is able to determine that a fall has occurred and the period ends before the referee strikes the mat, the fall shall be awarded� (See Rule 7�5�10�)
2�13�6 Determining Fall. If the referee cannot determine that a fall has occurred before the period ends because of crowd noise or other circumstances, the assistant referee, if available, shall be consulted� If there is no assistant or if the assistant referee is in doubt, the referee shall ask the match timekeeper if the signal hand hit the mat before the period ended� (See Rule 7�5�10�)
