BOSTON (CBS) — Before the Celtics open their head coaching search to outside candidates, the franchise is first interviewing a few in-house options. On Monday, that meant new president of basketball ops. Brad Stevens interviewed Celtics assistant coach Scott Morrison for the position.

Morrison officially interviewed for Stevens’ old job on Monday, according to Brian Robb of Mass Live. Morrison has been on Stevens’ staff in Boston since 2017, and was the G-League Coach of the Year in 2015 for his work with the Maine Red Claws. He also has experience as an assistant coach with Canada’s National Team.
