EUGENE, Ore. — Mike Bellotti is stepping down as Oregon's football coach to become the school's athletic director, and offensive coordinator Chip Kelly will be promoted to head coach.

Bellotti will become athletic director on July 1, taking over for athletic director Pat Kilkenny. Kelly will assume his role as head coach on March 30, the opening day of spring practice.

The move was previously announced in December, but no timetable was set for the transition.

Bellotti will serve in the interim as senior counselor to Kilkenny, who will step down on June 30.
