The NBA’s board of governors has approved two rule changes that will go into effect next season — a second coach’s challenge if the first one is successful and an in-game flopping penalty. The new rule on flopping means that when a referee now calls a flop, there will be a non-unsportsmanlike technical foul called on the offending players’ team, and the opposing team will get a free throw. Referees also won’t have to stop play to call a flop, as they can wait until the next stop in live action, if needed, to make the call. The flopping rule change will be utilized on a one-year trial basis.
