FIBA Rules 2017 – Art. 46 Crew chief: Duties and Powers

The crew chief is authorized to approve before the game and use, if available, an Instant Replay System (IRS) to decide, before he signs the scoresheet, when the game clock shows 2:00 minutes or less in the fourth period and in each extra period, to identify the player who has caused the ball to go out-of-bounds.

Don’t forget this:

•  If the call and the decision of the officials is subject to the IRS review, that initial decision must be shown by the officials on the playing court.
•  Following the IRS review, the initial decision of the official(s) can be corrected only if the IRS review provides the officials with clear and conclusive visual evidence for the correction.
•   After the IRS review has ended, the final decision shall be clearly reported by the crew chief in the front of the scorer’s table and if necessary, communicated to the coaches of both teams.

Art. 46 Crew chief: Duties and powers

46-11 Example: With 5:53 to play in the 1st period, the ball rolls on the playing court next to the sideline when both A1 and B1 try to get the control of the ball. The ball goes out-of-bounds and the ball is awarded to team A for the throw-in. The officials become uncertain of the player who caused the ball to go out-of-bounds.
Interpretation: The officials cannot use the IRS review at this time. To identify the player who caused the ball to go out-of-bounds the IRS review can only be used when the game clock shows 2:00 minutes or less in the 4th period and in each extra period.

Consider this:

• Makes accurate calls at the end of a close game. 

• Concentration – Positioning – Creates correct angles and  keep your eyes on your coverage area.
