Maine Red Claws D-League head coach Scott Morrision has been promoted to Boston Celtics assistant coach by C's coach Brad Stevens.

Morrision has coached the Celtics NBA Development League team for three seasons and his teams went 95-55.

The Red Claws won three straight division titles under Morrison and won a first ever playoff series this past season before bowing out in the D-League conference finals.

He is originally from Prince Edward Island and coached college hoops in Canada before joining the Red Claws.

NOTE: The NBA D-League is now the G-League (Gatorade) as of today. The NBA entered into a partnership to rebrand its developmental league.
