The sale of the Boston Celtics has been finalized. An investor group led by private equity mogul William Chisholm took control of the NBA’s most-decorated franchise from a group led by Wyc Grousbeck that had owned the team since 2002.

Further details of the Celtics sale, including more co-owners, were released by the team following approval from the NBA's Board of Governors.

The Celtics have made it official with the leadership structure between new governor Bill Chisholm and longtime owner Wyc Grousbeck.

There were concerns that he might not return after his contract was up, and his status in terms of health was unclear after a knee injury.

The Boston Celtics are officially under new leadership today, and it’s not just about a record‑setting price tag. The NBA Board of Governors has unanimously approved the $6.1 billion sale of the franchise to private equity executive and lifelong fan Bill Chisholm.
