In a shocking announcement that has sent waves through the basketball world, Boston Celtics head coach Joe Mazzulla confirmed earlier today that All-Star forward Jaylen Brown** has suffered an injury during a private off-season training session just weeks before the team’s pre-season training camp was set to begin.
Speaking at a hastily arranged press conference at TD Garden, Mazzulla appeared visibly concerned as he shared the unexpected update.
Jaylen sustained a lower-body injury while working out independently this week,” Mazzulla said. “While the full extent is still being evaluated, we can confirm he will miss at least part of the team’s pre-season preparation.”
Fans in Disbelief: “Not Again…”
The news has rocked Celtics Nation, with many fans expressing their frustration and disbelief online. Jaylen Brown, fresh off a stellar playoff run and a newly inked max contract extension, was expected to be a major force heading into the 2025–26 NBA season alongside Jayson Tatum.
This is déjà vu. We just got healthy, and now this?” posted one fan on X (formerly Twitter). Jaylen is our future. This better not be serious,” another user wrote, adding a series of anxious emojis.
Outside TD Garden, stunned fans gathered and shared their thoughts with reporters. It’s like a punch to the gut,” said Marcus D., a season ticket holder. “We were so hyped for this season — and now this cloud is hanging over everything.”
What Happened?
According to sources close to the team, Brown was participating in a closed-door training session with a personal trainer when he reportedly “landed awkwardly” after a high-intensity workout drill. While the team has not confirmed the specifics, insider reports suggest it could involve a **hamstring or knee issue**.
> “He felt discomfort right after the drill and stopped immediately. We’re being cautious, as we should,” Mazzulla added.
Medical evaluations are ongoing, and an MRI has been scheduled. The Celtics have promised to release a formal update once results are confirmed.
Celtics’ Season at a Crossroads?
Jaylen Brown’s health will be a major storyline heading into the new season. After reaching the NBA Finals just a year ago and narrowly losing to the Denver Nuggets, the Celtics were widely considered title favorites in 2025–26.
Brown averaged **24.8 points, 6.2 rebounds, and 3.7 assists** last season, forming one of the league’s most lethal duos with Tatum. Any extended absence would be a major blow to Boston’s championship hopes.
### What’s Next?
The Celtics are expected to make adjustments during summer training camp, potentially giving more minutes to younger players such as Jordan Walsh or newly acquired rookie DaRon Holmes II, depending on Brown’s timeline for return.
Mazzulla ended the press conference with cautious optimism:
> “Jaylen is a warrior. He’s doing everything right — resting, following protocol, staying focused. We’re not panicking, but we’re not downplaying it either.
