Joe Mazzulla honors Jaylen Brown during Celtics Media Day

Joe Mazzulla paid tribute to Jaylen Brown during the Boston Celtics' Media Day on September 28, 2026, acknowledging Brown's ten-year contribution to the team before he was traded to the Philadelphia 76ers. Mazzulla humorously remarked on losing the ability to foul newly acquired center Mitchell Robinson due to his free-throw issues. Mazzulla enters his fifth season as head coach after leading the Celtics to the championship in 2024 but faced a disappointing first-round exit last season. The team, having made significant offseason additions including Paul George and Robinson, is preparing for training camp, with preseason games set to begin on October 8 against the Cleveland Cavaliers.
