Grizzlies acquire Marcus Smart from Celtics in 3-team deal involving Kristaps Porzingis and Tyus Jones, sources say - ESPN

The Boston Celtics, Washington Wizards and Memphis Grizzlies agreed to a three-team trade late Wednesday night that sent center Kristaps Porzingis to the Celtics, guard Marcus Smart to the Grizzlies and guard Tyus Jones to the Wizards, sources told ESPN's Adrian Wojnarowski.

As part of the deal, Memphis is sending Boston its first-round pick in Thursday's draft — the 25th overall selection — as well as the Golden State Warriors' top-four-protected first-round pick in 2024, sources said, while the Celtics are sending the 35th pick in Thursday's draft to Washington. The Celtics are also sending forward Danilo Gallinari and center Mike Muscala to Washington as part of the deal, sources said.

The three-team deal came together in the minutes leading up to a midnight ET deadline for Porzingis to opt in to his $36 million player option for the 2023-24 season. With the deal completed, Porzingis did opt in, sources said.

The trade capped a long day of negotiations involving the Celtics and Wizards over a possible Porzingis deal, after the two teams first attempted to hammer out a three-team agreement with the LA Clippers that would've sent Malcolm Brogdon to Los Angeles, the 30th pick in the draft to the Wizards and Porzingis to the Celtics.

But when that deal fell apart, Boston pivoted to talks with Memphis, allowing this deal to come together just before the deadline.

For the Celtics, the deal presents a radical shift in what their team will look like.

Porzingis, who will turn 28 on Aug. 2, had arguably the best season of his NBA career this past year in Washington, averaging a career-high 23.2 points to go along with 8.4 rebounds, 2.7 assists and 1.5 blocks in 65 games for the Wizards. The fourth overall pick in the 2016 NBA
