The NBA says Major Gen. Ronald Johnson will resign as senior vice president of referee operations at the end of July.
Johnson joined the league in 2008 to head a newly formed department following the betting scandal involving former referee Tim Donaghy. Johnson had spent 32 years as an Army combat engineer, and says Thursday in a statement that he feels he has accomplished his mission of improving the management of the league's officials.
Commissioner David Stern says Johnson fostered ''a culture of compliance and discipline that is at the core of any officiating program's success,'' and wished him well in future endeavors.
The league says it will begin the process of finding Johnson's replacement.
