Boston rolled out a starting five of Curtis Jones, John Tonje, Tucker DeVries, Dillon Mitchell, and Chris Cenac Jr. shortly before tip-off. Gonzalez and center Amari Williams were unavailable, per team updates.
No official injury report or explicit reason was given for either absence. The scheduling context, however, was notable: Boston had defeated the Charlotte Hornets the day prior and was in the middle of a three-games-in-four-days stretch.
With Gonzalez’s absence, the storyline carried extra weight because the 20-year-old had been central to Boston’s 2-0 start in Las Vegas. The Celtics entered the Atlanta game undefeated, matching the Hawks.
Gonzalez had already made his Summer League impact. He opened the slate with an all-around performance against the Toronto Raptors, contributing 17 points, 10 rebounds and eight assists in an 83-80 overtime win. He followed that with a strong showing in Boston’s 87-75 victory over Charlotte, contributing on the glass, facilitating ball movement and applying pressure on defense, even if his shooting wasn’t always falling.
Through the first two games, Gonzalez was averaging about 15.5 points and seven rebounds. Beyond the raw numbers, he had begun shouldering more offense after spending his rookie season in a limited role. The 6-foot-6 wing, selected with the No. 28 pick in the 2025 NBA draft, entered Summer League with an opportunity to handle the ball more, initiate possessions, and demonstrate that his game extends beyond defense and transition play.
With Gonzalez and Williams out, Boston shifted two prominent young core members into the starting lineup. Cenac, the No. 27 pick in the 2026 draft, started at center against Atlanta. He had already shown flashes as a rim protector and connecter, including a game-tying three against Toronto that forced overtime. Mitchell followed up a standout performance against Charlotte, where he posted 24 points, eight rebounds and six steals, using his athleticism to create extra possessions and score in transition.
Gonzalez’s absence also meant increased ballhandling duties for Jones and more scoring opportunities for Tonje and DeVries. This is part of the value of Summer League beyond wins and losses: sitting Gonzalez and Williams allowed Boston to evaluate how the rest of the roster functioned without their more experienced performers.
For Gonzalez, missing one July game should not obscure what he displayed during the opening weekend. He showed improved ball-handling, improved rebounding from the wing, and the defensive activity that helped him earn NBA minutes. Boston will decide whether Gonzalez returns later in the Summer League schedule or if the team feels it has seen enough from its second-year wing.
The overarching takeaway is that Summer League continues to be a proving ground for younger players to demonstrate versatility and readiness for expanded roles, while teams assess how complementary pieces fit around their established prospects.
