Boston Celtics have officially released the 2026 NBA Summer League schedule, kicking off on July 12 and running through July 22. The Celtics will host three games at the TD Garden before traveling to Las Vegas for two more matchups. The league gives rookie guard Payton Pritchard a chance to log minutes alongside veteran Jayson Tatum in a low‑pressure setting.
What does the schedule look like?
The first contest arrives on July 12, when Boston faces the New York Knicks in a 40‑minute opener. Two days later, the Celtics meet the Chicago Bulls, followed by a July 16 showdown with the Los Angeles Lakers. After a brief travel break, the team flies to the Vegas Summer League for a July 19 game against the Golden State Warriors and wraps up on July 22 versus the Miami Heat. All games will be streamed live on NBA.com and the official NBA app.
Why is the Summer League important now?
The Celtics entered the summer league after a 100-109 loss to the Philadelphia 76ers on May 2, 2026 and a five‑game losing streak (0‑0‑5). Coach Joe Mazzulla sees the tournament as a chance to test new rotations and evaluate the progress of second‑year players like Jabari Walker. With the Eastern Conference tightening, early chemistry could translate into a stronger start when the regular season opens in October.
Which players could break out?
Rookie Mason Plumlee is expected to showcase his rebounding instincts, while Derrick White will likely run the pick‑and‑roll alongside Tatum. The league also offers a platform for undrafted free agents to earn a two‑way contract. Scouts will be watching the perimeter shooting percentages closely, especially from the three‑point line where the Celtics aim to improve beyond the 35% mark recorded last season.
What comes after the Summer League?
After July 22, Boston returns to Boston for training camp on August 5. The schedule gives the front office a week to decide on any last‑minute roster moves before the preseason begins on September 30. Fans can expect a press conference on August 10 where Mazzulla will outline the final roster and discuss how the summer league performances shaped his decisions.
The 2026 Summer League provides a low‑stakes environment, but for a team fresh off a five‑game skid, every rebound, assist and defensive stop matters. Celtics supporters should tune in each night, because the lessons learned in Vegas could be the difference between a playoff berth and a rebuilding year.
