The Celtics are trading Williams to the Mavericks in a three-team sign-and-trade deal that routes Reggie Bullock and draft capital to the Spurs, while Boston will net two second-round picks, according to multiple reports.

Williams, a restricted free agent, agreed to a four-year, $53 million deal to help make the trade to Dallas happen, per ESPN.

Dallas is also securing two second-round picks in the move, and the Spurs are acquiring an unprotected Mavericks pick-swap in 2030.

ESPN reported that the Celtics will also get a $6.2 million trade exception.
