The league's Board of Governors gave approval to the larger roster on Thursday. Previously, teams were allowed to have 15 players on the roster, but only 13 could be designated as active for a game.
In a separate decision, the Board of Governors backed the league's Competition Committee recommendation to make the coach's challenge a regular part of league rules. Saying coaches were "receptive to the pilot version," NBA President of League Operations Byron Spruell added that they became more comfortable "with the concept and strategic aspects as the season progressed."
