NEW YORK -- Instant replay of out-of-bounds violations in the final two minutes of regulation or overtime of NBA games this season will be initiated by a coach's challenge rather than by referees.

The NBA's Board of Governors approved the change Wednesday on a one-year trial basis.

Under the previous rule, coaches could not challenge an out-of-bounds ruling within the final two minutes. The change allows coaches to challenge an out-of-bounds ruling at any point in the game.
