The alterations take effect starting with Friday's preseason games.
Replay was expanded to include situations where officials are not sure a team had an improper number of players on the court during game action.
Current rules also were modified to allow instant replay review during the final two minutes of overtime rather than the entire overtime period. Replay will continue to be permissible during the final two minutes of the fourth quarter.
Replay now will be used when officials are not certain which team should get possession after the ball goes out of bounds. In the past, officials could only use replay to determine which player caused to ball to go out of bounds. - Reuters
