Dennis Lindsey, Utah's new general manager, declined comment.
Oddly, Layden will be replacing Lindsey in San Antonio's front office.
On Aug. 7, O'Connor announced he was giving up his duties as general manager. Lindsey was hired as his successor.
Less than a month later, Layden has decided to leave Utah after spending 25 years with the franchise.
He started as an administrative assistant and scout in 1981. He was named an assistant coach in 1984 and became the director of player personnel in 1989.
Layden was named the vice president of basketball operations three years later and, after the 1994-95 season, he was honored as the NBA's Executive of the Year when the Jazz won 60 games.
Layden left Utah to become president and general manager of the New York Knicks in 1999.
He was fired on Dec. 22, 2003 and eventually returned to the Jazz as an assistant for then-head coach Jerry Sloan, who resigned midway through the 2010-11 season.
Corbin replaced Sloan.
With Layden's departure, Corbin has only two assistant coaches on his staff Sidney Lowe and Jeff Hornacek.
