The 2026 NBA Playoffs are here, and one of the most storied rivalries in the East is set to ignite once again. After a well-earned rest following the regular season, the Boston Celtics are ready to host the Philadelphia 76ers in a highly anticipated Game 1 this Sunday afternoon.

Entering as the No. 2 seed, the Celtics have their sights set on another deep postseason run, just two years removed from capturing their historic 18th championship. The late-season return of superstar Jayson Tatum provided a massive boost, but as every fan knows, the intensity of the playoffs is a different beast entirely.

Standing in their way are the battle-tested 76ers, who punched their ticket with a gritty Play-In Tournament victory over the Orlando Magic. Philadelphia will look to Tyrese Maxey, who dropped a team-high 31 points in that win, to lead the charge against their Atlantic Division foes.

Ready to catch every moment of this epic showdown? Here’s everything you need to know to tune in for Celtics vs. 76ers, Game 1.

The action will be broadcast nationally on ABC. For cord-cutters, you can stream the game live through the ESPN app, ensuring you won't miss a single fast break or clutch three-pointer.

Mark your calendars and set your alarms! The first tip-off of this first-round series is scheduled for 1 p.m. ET on Sunday, April 19. The atmosphere will be electric at TD Garden in Boston, where the Celtics will look to defend their home court and set the tone for the series.
