The Boston Celtics are finalizing a three-team deal that'll send forward Grant Williams to the Dallas Mavericks, sources told The Athletic's Shams Charania.
Williams, a restricted free agent, will pen a four-year, $53-million contract as part of a sign-and-trade agreement to join the Mavericks, sources told ESPN's Adrian Wojnarowski.
The San Antonio Spurs will reportedly receive Mavericks wing Reggie Bullock and the right to swap picks with Dallas in 2030 as a part of the deal. Meanwhile, both the Celtics and Mavericks will each acquire two second-round selections, according to Wojnarowski.
Williams emerged as a key piece of the Celtics' rotation over the past two campaigns, during which he averaged eight points, 4.1 rebounds, and 1.3 assists while shooting over 40% from deep. The 24-year-old was also occasionally thrust into the starting lineup in that span, making 44 starts in 156 contests.
Bullock spent the past two years in Dallas following a pair of seasons with the New York Knicks. In 78 appearances with the Mavericks in 2022-23, the 32-year-old started 55 games and registered 7.2 points, 3.6 rebounds, and 1.4 assists per game while shooting 38% on 5.1 attempts from distance.
The reported acquisition of Williams is Dallas' second significant transaction Wednesday. The team also reportedly signed Portland Trail Blazers restricted free agent Matisse Thybulle to an undisclosed offer sheet. However, the Blazers have two days to match Dallas' terms.
