The Jaylen Brown-for-Paul George blockbuster became official Monday afternoon.

After the NBA’s moratorium on trades was lifted, the Celtics confirmed they had dealt Brown to the Philadelphia 76ers in exchange for George, two first-round draft picks and two second-round picks.

The trade ends Brown’s 10-year run with the Celtics, during which he appeared in 816 games, scored the 10th-most points in franchise history and helped lead Boston to an NBA championship in 2024.

In his final season on Causeway Street, the 29-year-old finished as the NBA’s fourth-leading scorer (28.7 points per game), made second-team All-NBA and received the sixth-most NBA MVP votes. He spearheaded an underdog Celtics squad that won 56 games before losing to his new team, the rival Sixers, in the first round of the playoffs.

“Jaylen Brown will rightfully go down as one of the defining players of this era,” Celtics president of basketball operations Brad Stevens said in a statement. “Like the best Celtics before him, he is a terrific player and has also had a huge impact off the court. On a personal level, I am thankful to have had a front-row seat to the first 10 years of his illustrious career. I could go on and on, but a few sentences, paragraphs, or even chapters wouldn’t do it justice. His legacy as a Celtic is forever etched in stone.”

Stevens also spoke highly of George, a nine-time All-Star who battled injuries throughout his stints with the 76ers and Los Angeles Clippers. His statement suggested the Celtics do not plan to flip the 36-year-old in a subsequent deal.

“Paul George has been one of the best two-way wings of the last decade in the NBA and can easily fit into any group,” Stevens said. “He’s looking forward to joining the Celtics, and we’re excited to welcome him and his family.”

In their trade announcement, the Celtics detailed the complicated conditions of the draft picks they received from Philly. Those are as follows:

— A 2028 first-round pick (the LA Clippers’ own) that, if it is top 16, instead becomes the unprotected right for Boston to swap its currently held 2028 first-round pick (the worst of Boston’s and San Antonio’s) with the better of the LA Clippers’ or (if Philadelphia’s is top 8) Philadelphia’s 2028 first-round pick

— Philadelphia’s 2031 unprotected first-round pick

— The most favorable 2028 second-round pick among Golden State’s, Milwaukee’s or Oklahoma City’s

— The most favorable 2030 second-round pick among Phoenix’s, Portland’s or Washington’s

Stevens and Celtics majority owner Bill Chisholm are scheduled to hold a news conference at 4 p.m. on Monday.
