After seven years as National Basketball Association Development League president, Dan Reed has resigned to take a new job, league sources told Yahoo Sports.

Reed will take a job running sports partnerships at Facebook, sources told Yahoo Sports.

Under Reed, the D-League, the NBA's minor league system, has expanded significantly in scope. There are 18 teams, including 15 with direct one-on-one hybrid partnerships with franchises.
