NBA approves coach's challenge on one-year trial

The NBA approved a coach's challenge for the upcoming season on a one-year
trial basis. Teams get just one challenge per game, even if it is a successful
challenge, although plays still will be reviewed without the need for a
challenge in the final two minutes of regulation or overtime.

A coach's challenge has been used in the G-League the past two seasons and
currently is being used in the NBA Summer League in Las Vegas. A team must
have a timeout in order to challenge a play with the coach requesting the
challenge by putting a finger in the air and rotating it in a circle.

If a team requests a challenge without a timeout, a technical foul will be
called, and the play will not be reviewed.

Plays that can be reviewed include personal fouls called on a team, basket
interference, goaltending and a ball out of bounds.

The NBA has also upgraded its procedures to verify a 2- or 3-point basket in a
timely fashion, as well as for a shot-clock violation. A courtside
administrator will be on hand at every game to speed up communication with
replay officials at NBA offices in Secaucus, N.J.
