Boston Celtics' Jaylen Brown Undergoes Knee Surgery, Expected to Return for Training Camp.

Boston Celtics star Jaylen Brown underwent arthroscopic surgery on his right knee, but is expected to be ready for training camp without limitation. Brown, 28, finished the playoffs with a partially torn meniscus and averaged 22.1 points and 7.1 rebounds per game. The four-time All-Star and 2025 NBA Finals MVP averaged 22.2 points, 5.8 rebounds, and 4.5 assists in 63 games this season.

Boston Celtics star Jaylen Brown underwent arthroscopic surgery on his right knee, the team announced. The procedure was an arthroscopic debridement, which involved removing pieces of loose bone and cartilage. Brown, who turned 28 earlier this year, is expected to participate in training camp without limitation, according to the Celtics [1].

Brown's injury was initially reported as a bone bruise and posterior impingement, but it later emerged that he was also playing through a partially torn meniscus [3]. The injury was suffered before the NBA All-Star break in February and persisted through the playoffs. Despite managing the injury, his performance suffered, with March 2025 being his lowest-scoring month since 2019 [3].

In the playoffs, Brown averaged 22.1 points and 7.1 rebounds per game, despite the injury. His performance was notable as the Celtics co-star Jayson Tatum was sidelined with a wrist injury and later ruptured his Achilles against the New York Knicks [3]. Brown's season-long field-goal and 3-point field-goal percentages ranked among the worst of his career, but he set a personal best in assists per game (4.5) [3].

The Celtics have not announced a timeline for Tatum's recovery, but his father offered an expected rehab timeline of "eight to nine months" [3]. Tatum's absence could influence the team's roster decisions this offseason, potentially leading to a more drastic overhaul of the championship-winning core [3].

Brown's recovery is expected to be smooth, with the Celtics expressing optimism about his prognosis. The team's president of basketball operations, Brad Stevens, said, "The reality is we have a ton of good players and everyone leans on. That said, Jaylen and Jayson have gotten the majority of attention because of how good they are. And I have full faith that any game that you have those guys on the court, or one of those guys on the court, you have a great shot. And so I have full faith in Jaylen" [3].
