NEW YORK – NBA G League referees John Butler, Nate Green and Evan Scott have been promoted to full-time NBA staff officials, it was announced today by Monty McCutchen, NBA Vice President, Head of Referee Development and Training.

“John, Nate and Evan have achieved their promotions through the quality of their officiating being at the standard for working NBA games on a regular basis,” said McCutchen.  “Our NBA G League is a great tool for officials to earn the right to rise to the NBA ranks and then continue to grow at their craft.”

In addition to their NBA assignments this season, the three new staff officials will continue to officiate NBA G League games.  All NBA referees with fewer than four years of service in the NBA work NBA G League games to gain additional experience as crew chiefs and develop as leaders.
