NEW YORK — The NBA G League will use four referees for preseason and regular-season games through November and expand its playoffs from eight to 12 teams.
The NBA's minor league experimented with four- and five-person referee crews rather than the traditional three-person crews for nine regular-season games last season.
Nearly half the 26-team league will qualify for the four-round post-season under the changes announced Wednesday.
The new format will give berths to each of the six division winners, with the remaining six spots filled by three wild-card teams in each conference with the best regular-season records.
The top two seeds in each conference will earn byes into the second round. The playoffs will begin with three single-elimination rounds before culminating with a best-of-three NBA G League Finals.
The 50-game regular season tips off on Nov. 3.
— Overtime periods will be reduced from three to two minutes.
— Clear path reviews were scrapped, leaving five instant replay triggers.
— The coach's challenge has been revised to one per game. It can be used any time to challenge fouls, goaltending/basket interference and out-of-bounds calls.
