Jaylen Brown Full-Go at Celtics Practice Ahead 2025–26 Season Opener

Jaylen Brown is recovering well from a left hamstring injury sustained during the Boston Celtics' preseason finale and participated fully in practice ahead of the 2025-26 regular season opener against the Philadelphia 76ers. Despite exiting the preseason game early, Brown described the injury as a minor tweak and is optimistic about playing, though he remains cautiously taking it day by day. With superstar Jayson Tatum sidelined due to a ruptured Achilles, Brown is expected to be the team's primary scoring option and take on a significantly larger role this season. Celtics head coach Joe Mazzulla has noted Brown's full participation in practice and praised the team's new fast-paced, high-energy style designed to compensate for offseason roster losses. Brown's health is crucial for the Celtics, who have a reshaped roster featuring younger, less proven players. Former Knicks coach Tom Thibodeau also visited practice to provide insights from a previous playoff series against Boston, aiding the team's preparation.
