The Sixers will face the Celtics twice in the 2026 preseason, with games scheduled for Oct. 10 in Boston and Oct. 16 at home. These matchups are particularly significant following the Sixers’ playoff victory over the Celtics and their recent trade involving Jaylen Brown. The complete preseason schedule is still pending, and the Sixers are set to compete in East Group B for the 2026 NBA Cup, alongside the Knicks, Cavaliers, Heat, and Pacers.
