Joel Embiid Drops 34 as 76ers Stun Celtics in Game 7 Upset, Advance to Face Knicks
Joel Embiid delivered 34 points in a commanding performance as the seventh-seeded Philadelphia 76ers eliminated the second-seeded Boston Celtics 109-100 in Game 7 on Saturday, May 2, completing one of the most significant first-round upsets in recent NBA playoff history. The Celtics, hampered by the absence of star forward Jayson Tatum — sidelined with left knee stiffness — could not overcome Embiid's dominance, and Philadelphia now advances to the Eastern Conference Semifinals to face the New York Knicks beginning Monday, May 4.
Background
The 76ers entered the series as heavy underdogs. Philadelphia finished the regular season as the seventh seed in the Eastern Conference, while Boston — the defending conference finalist — held the second seed with one of the league's most balanced rosters. The Celtics had depth, shooting, and home-court advantage. Philadelphia had Embiid, a healthy and motivated version of the franchise center who had battled injuries throughout the regular season.
The series was tightly contested from the start. Boston won Games 1 and 2 at home, but Philadelphia responded with back-to-back wins in Games 3 and 4 to level the series. The Celtics reclaimed the lead with a Game 5 victory before the 76ers forced a decisive game with a 106-93 win in Game 6. Throughout the series, Embiid averaged over 30 points per game, repeatedly willing his team back from the brink.
Key Developments
Tatum's absence proved decisive. The Celtics' leading scorer and primary offensive engine was ruled out hours before tip-off with left knee stiffness, removing Boston's most reliable shot creator and forcing the team to redistribute offensive responsibilities. Jaylen Brown led Boston with 28 points, but without Tatum's gravity and playmaking, the Celtics' offense became predictable and easier to defend.
Embiid was relentless. He attacked the paint repeatedly in the first half, drawing fouls and converting at the free-throw line with unusual efficiency. By the third quarter, Philadelphia had built a double-digit lead that Boston's depleted offense could not overcome. The 76ers' supporting cast — including Tyrese Maxey, who added 22 points — provided enough secondary scoring to prevent any Celtics comeback.
The broader first-round picture in the East was equally dramatic. The Detroit Pistons forced a Game 7 against the Orlando Magic after rallying from a 24-point deficit in Game 6 to win 93-79. The Cleveland Cavaliers were denied a series-clinching win at home when RJ Barrett hit a game-winning three-pointer in overtime to give the Toronto Raptors a 112-110 victory in Game 6, extending that series as well. In the West, the Los Angeles Lakers eliminated the Houston Rockets 4-2, and the Minnesota Timberwolves advanced past the Denver Nuggets.
Why Americans Should Care
The Celtics-76ers rivalry is one of the NBA's most storied, rooted in the fierce battles of the 1980s between Larry Bird and Julius Erving. This upset rekindles that rivalry's intensity and sets up a Philadelphia-New York second-round matchup that will dominate sports conversation on the East Coast. For fans in Pennsylvania, the 76ers' run represents a genuine championship contender emerging from a franchise that has spent years rebuilding. In New York, the Knicks — who swept the Atlanta Hawks in the first round — now face a motivated Embiid who has never advanced past the second round. The series begins Monday at Madison Square Garden, and ticket prices on the secondary market have already surged past $400 for lower-level seats.
Why It Matters
This upset underscores a defining trend of the 2026 NBA playoffs: the collapse of seeding as a reliable predictor of outcomes. Through the first round, teams scored under 100 points in 29% of games — up sharply from 11% during the regular season — as defensive intensity and physical play have neutralized high-powered offenses. The league's offensive rating dropped 4.3 points per 100 possessions from the regular season to the playoffs, the largest such decline on record. This mirrors the defensive-first playoff basketball that defined the 1990s and early 2000s, when teams like the Detroit Pistons and San Antonio Spurs won championships through suffocating defense rather than offensive firepower. The injury factor also looms large: Tatum's absence recalls the 2019 Finals, when Kevin Durant's injury reshaped the entire championship picture. The NBA's grueling 82-game regular season continues to generate questions about player load management and whether the league's best players arrive at the playoffs physically compromised.
What's Next
The 76ers face the Knicks in Game 1 of the Eastern Conference Semifinals on Monday, May 4, at Madison Square Garden. Philadelphia will need Embiid to sustain his playoff form against a Knicks defense that held Atlanta to under 100 points in multiple games. Boston's offseason will center on Tatum's knee health and whether the team's core can remain competitive heading into 2026-27. The Western Conference Semifinals feature Oklahoma City Thunder against the Lakers and the San Antonio Spurs against the Timberwolves — matchups that will determine whether the West produces a new champion or a familiar face.
