After a summer of dramatic roster change, the Miami Heat are reassigning two prominent assistant coaches, league sources told Yahoo Sports.

Ron Rothstein and Bob McAdoo will no longer play significant roles on head coach Erik Spoelstra's staff – and are completely off the bench, according to league sources.

Those changes will clear the way for Juwan Howard to be promoted from his role in player development, league sources said.

It is immediately unclear what role Rothstein and McAdoo will have in the organization, but both are expected to continue to have jobs with the Heat, league sources said. Heat president Pat Riley and Spoelstra have long professional and personal ties with both men.

Heat assistant coach David Fizdale has ascended to the top assistant role under Spoelstra in recent years and will continue working closely with the head coach. Fizdale is considered a future head coach in the NBA.

Rothstein, 71 was the franchise's first head coach, serving three years beginning in 1988 and returned to the franchise in 2000 to coach Miami's WNBA entry. For the past decade, he's worked as an assistant coach under head coaches Stan Van Gundy, Riley and Spoelstra.

McAdoo, a Hall of Fame player, has spent 18 years as a Miami Heat assistant, a relationship bonded with Riley back to their years together as coach and player with the Los Angeles Lakers in the 1980s.

Miami has advanced to the NBA Finals in four straight years and won two titles during that time. The Heat lost 4-1 in a best-of-seven series to the San Antonio Spurs in 2014 NBA Finals, a prelude to star LeBron James leaving Miami to rejoin the Cleveland Cavaliers in free agency.
