The Boston Celtics have hired Darren Erman as Director of NBA Scouting, according to sources.

Erman had been a coaching assistant with the Celtics for four years before joining the Golden State Warriors as an assistant coach.

Erman was fired by the Warriors for "a violation of company policy", which sources say stemmed from a single taped conversation of coaches who had been working to undermine his game preparation and relationships with players.

Erman had other job opportunities before rejoining the Celtics, including reuniting with Doc Rivers.
