2. When clarification is needed, delay and extend the other hand, palm down toward the fouling player's hips (bird dog signal)
3. While holding the foul signal, move toward the play and near the fouling player, stop and verbally inform the player that he/she fouled by stating the jersey color and number.
4. Lower the foul signal and indicate the nature of the foul by giving a preliminary signal.
5. If a team control foul, signal in the direction of the non-fouling team's basket. If a shooting foul, verbally give free-throw shooter's number to the shooter and the other officials. Visually give the number of free throws to the non-calling official.
6. Indicate the throw-in spot if a throw-in will follow.
7. If a basket has been scored, signal to count as soon as it is legally scored. If a try attempt is not to be awarded (whether or not the attempt is good), immediately wipe off the attempt with the appropriate signal.
8. Do not be in a rush to leave the play area if players are in close proximity or on the ground. Attend to the dead-ball situation at the point of the play before leaving to report to the table.

And now for dessert, who follows the prescribed procedures, particularly as it applies to step 4?
