NEW YORK (AP) -- The NBA says executive vice president of basketball operations Stu Jackson is leaving his position on Aug. 1, and Rod Thorn will return to the league office as president of basketball operations.

Jackson spent more than 13 years at the league. In his current position, he is in charge of all rules, conduct and discipline on the court. He informed Commissioner David Stern and other league officials that he planned to step down. He has been involved in college or pro basketball for more than three decades.

"Stu has made enormous contributions to the NBA over the past 13 years,'' Stern says Wednesday in a statement.

Thorn previously spent 14 seasons at the NBA office and has been a successful team executive with Chicago, New Jersey and Philadelphia.
