NBA Scores: Pistons Stun Celtics 121-113 in Season Opener
The first entry in the 2026-27 NBA scores books belongs to the Detroit Pistons, who erased a 22-point deficit and stunned the Boston Celtics 121-113 on Tuesday afternoon at Little Caesars Arena. The season opener — a rare weekday matinee tipping at 3:00 p.m. ET — delivered one of the most dramatic opening-day comebacks in recent memory, spoiling a historic Boston debut from Paul George and a new era of Celtics basketball.
For anyone checking who won the game last night, the answer is Detroit, and the way it happened was remarkable. The Celtics controlled the first two and a half quarters, built a lead as large as 22 points, and watched George set a franchise record for points in a Boston debut. Then the Pistons ripped off an 18-0 run that flipped a double-digit deficit into an eight-point lead in a matter of minutes, followed by a devastating 23-0 surge that left the Celtics reeling on their way to an 0-1 start.
The game was carried nationally on NBC and Peacock as part of the league’s opening-night showcase, giving the entire NBA news cycle a full day of material: a statement comeback, a record-setting debut, an injury scare to a new acquisition, and a reminder that last season’s surprise Eastern Conference leaders from Detroit are not going away quietly.
Who Won the Game Last Night: Pistons 121, Celtics 113
The final box score tells a story of two games in one. The first three quarters belonged to Boston; the fourth belonged entirely to Detroit.
Boston opened with the energy of a team eager to define a new identity, jumping out to a 28-27 lead after the first quarter behind Jayson Tatum’s all-around work — seven points, four assists and three rebounds in the opening 12 minutes, capped by a leaning jumper at the buzzer. The Celtics then put together their best stretch of the afternoon in the second quarter, outscoring the Pistons 30-18 to take a 58-45 lead into halftime. A Kevin Huerter three-pointer at the halftime horn was waved off for leaving his hands after the buzzer, a small mercy for Boston that still left the margin at 13.
The third quarter brought more of the same: George pouring in points, the Celtics stretching the lead. Baylor Scheierman’s three-pointer off a Tatum pass just before the third-quarter buzzer kept Boston ahead 88-82 entering the final frame. The Celtics then opened the fourth quarter with a quick burst to go up 96-84, a 12-point cushion with the home crowd quiet.
That is when everything flipped. Duncan Robinson drilled back-to-back three-pointers to cut the lead to four with 7:34 remaining, forcing Boston coach Joe Mazzulla to call timeout. It did not help. The Pistons poured in points on consecutive possessions while the Celtics suddenly could not buy a basket, completing an 18-0 run that put Detroit ahead 107-99 with 5:10 left. The avalanche continued — a 23-0 run in total — before a Derrick White layup finally stopped the bleeding. Detroit closed out a 121-113 final, outscoring Boston 39-25 in the fourth quarter alone.
Paul George Makes Celtics History in a Losing Debut
The cruelest irony of opening night for Boston is that its newest star was brilliant. Paul George, acquired from the Philadelphia 76ers in the offseason blockbuster that sent Jaylen Brown the other way, authored one of the great debuts in Celtics history — and it came in a loss.
George scored 31 points through three quarters, shooting 10-of-14 from the field including 6-of-8 from three-point range and a perfect 5-of-5 from the free-throw line, adding three rebounds, an assist, and a flurry of steals and blocks that had the NBA’s official accounts buzzing. According to the league’s official PR page on X, George set the Celtics’ franchise record for most points in a debut performance.
“Paul George has set the record for most points in a Celtics debut, surpassing Kristaps Porziņģis’ 30 points in 2023. George has 31 points with the third quarter still in progress,” the league’s account posted.
The milestone moments kept coming. His 2,451st career three-pointer moved him past Kyle Korver into eighth place on the NBA’s all-time list for three-point makes, leaving only seven players in league history ahead of him. By halftime he already had 17 points, and his 11 points in the first four minutes of the third quarter were, to that point, the most any player had ever scored in a Celtics debut. Social media lit up with the highlights: an and-one, a pull-up jumper followed by a feed to Derrick White for an open three, and a celebratory reaction after a deep make that the league’s own account shared with a laughing emoji.
For Boston, the performance offered exactly what the franchise hoped the trade would deliver. The Celtics are playing without Jaylen Brown on the roster for the first time since the 2015-16 campaign, and the organization’s bet is that George — at 36 years old and, by his own timeline, in the back end of his career — can shoulder the two-way wing load alongside Tatum. For one afternoon, that bet looked inspired. The problem was everything around him in the fourth quarter.
NBA Trade Rumors Era: Boston’s Bold Offseason Gamble
To understand why this opener mattered so much to Boston, rewind to the summer. The Celtics’ front office made the defining move of the NBA trade rumors season: Jaylen Brown to Philadelphia, Paul George to Boston. It was the kind of franchise-altering swap that only comes along every few years, and it instantly reframed the Celtics’ championship window.
Brown had been a Celtic for a decade, a Finals MVP-level cornerstone who grew up in Boston’s system. Moving him was a declaration that the organization believed a different kind of star — a veteran two-way wing with a historically quick trigger from deep — gave this group its best chance. George arrived with a Hall of Fame résumé and a reputation for starting seasons hot; as one analyst noted during the game, when he is healthy and right, few players in the league can bend a defense the way he can.
The supporting moves mattered too. Boston signed Mitchell Robinson away from the New York Knicks, adding a rim-running, shot-blocking center to a rotation that needed exactly that. The double-big lineups — Robinson alongside Neemias Queta — were a feature of the first half, and Robinson threw down an alley-oop slam from Derrick White for his first basket in green.
The backdrop made the night even more layered: while Robinson was making his Celtics debut in Detroit, his former Knicks teammates were across the league collecting their championship rings and raising the banner at Madison Square Garden. The defending champions opened their title defense the same night their former center opened a new chapter. Robinson’s stint in Boston, it turns out, got off to a rocky start.
Player Injury Update: Mitchell Robinson’s Ankle Scare
One of the few genuine concerns to emerge from Boston’s opener was the health of its new center. Early in the second quarter, shortly after his alley-oop slam, Mitchell Robinson appeared to roll his ankle awkwardly on a play. He came up limping as the game went to a media timeout, and though he stayed on the court when play resumed — even appearing determined to keep going — the sight of a 7-footer favoring an ankle in his first game for a new team is never what a coaching staff wants to see.
Robinson’s final line reflected a disrupted night: 18 minutes, four points, three rebounds, one assist, one steal and two blocks, shooting 2-of-2 from the field but 0-of-2 from the free-throw line. The numbers were, as one analyst put it, underwhelming for a debut — but the ankle clearly limited him after the second quarter.
The Celtics will be watching this one closely. Robinson was signed to anchor the paint and protect the rim, and Boston’s depth at center would be tested quickly if he misses time. No official update on the severity of the ankle issue had been released by the end of the night, making this the player injury update to watch in the coming days. For a team that just reshaped its identity, losing a key offseason addition in game one would be a brutal twist.
How to Watch the Game Live: NBC and Peacock Carried the Matinee
For fans who missed the afternoon action, the opener was part of the NBA’s new-look national broadcast package, airing on NBC and streaming on Peacock as “NBA Tip-Off.” The 3:00 p.m. ET start — a deliberate matinee slot for opening day — gave the league a standalone afternoon window before the evening’s championship banner ceremony at Madison Square Garden.
The broadcast delivered plenty of viral moments. White’s alley-oop to Robinson, George’s heat-check threes, Tatum’s buzzer-beating leaner to end the first quarter, and Scheierman’s corner three at the end of the third all made the rounds on social media within minutes. The league’s accounts leaned into the history: George passing Korver, George’s debut record, and the comeback itself all got the full highlight treatment.
For the rest of the season, the how-to-watch picture for these two teams follows the usual national and local splits, with NBC and Peacock carrying a heavy slate of marquee games. If opening night is any indication of the drama in store, the rematch — whenever the schedule brings these two back together — will be appointment viewing.
Fourth-Quarter Collapse: Anatomy of the 23-0 Run
The defining stretch of the game deserves a closer look, because collapses this complete are rare. Boston led by 12 early in the fourth. Then, in the span of roughly seven minutes of game time, the Celtics were outscored 23-0.
It started with Duncan Robinson, the veteran sharpshooter, hitting consecutive threes to make it a four-point game. Mazzulla’s timeout was supposed to steady the ship. Instead, the Pistons kept coming: former Celtic Javonte Green drilled a momentum three during the surge, the defense tightened, and Boston’s offense ground to a halt. Tatum missed a layup on one possession and threw a pass into the second row on the next — the kind of sequence that tells you a team has lost its composure.
By the time White’s layup ended the run, Detroit had gone from down four to up 13. The Celtics never seriously threatened again. For a team that spent the first three quarters looking like a well-oiled machine, the fourth quarter was a systems failure on both ends: no stops, no buckets, no answers.
Give Detroit its due. This was not Boston handing the game away so much as the Pistons taking it. The defensive intensity ramped up quarter by quarter — NESN’s live updates noted Detroit “ramped up the defensive intensity” as early as the third — and by the fourth, the Pistons were the aggressors in every phase. That is the mark of a team that believes it belongs at the top of the conference.
NBA Standings: What Opening Night Means for the East
One game does not define a season, but the early NBA standings carry a symbolic weight on opening night, and Detroit sitting at 1-0 atop the Eastern Conference picture while Boston starts 0-1 is exactly the kind of statement the Pistons wanted to make.
Remember the context: last season, Detroit authored one of the league’s best stories, an impressive run to the top of the Eastern Conference standings that few saw coming. The Celtics and Pistons finished as the East’s top two seeds. The preseason narrative in Detroit was simple — prove it wasn’t a fluke. Beating Boston, on opening night, after trailing by 22, is about as emphatic a proof of concept as October basketball allows.
For the Celtics, the 0-1 start comes with a longer view. New roster, new pecking order, a superstar still learning his teammates’ tendencies — growing pains were always likely. The concerning part was not the loss itself but the manner of it: a 22-point lead evaporating into a 23-0 run suggests a team that has not yet learned how to close games together. Mazzulla will have film to study, and plenty of it.
Around the league, opening night also belonged to the defending champions in New York, where the Knicks raised their banner. The East’s hierarchy — the Knicks at the top, the Pistons and Celtics jockeying behind them — will be one of the season’s defining storylines, and Tuesday’s result scrambled the early order.
What’s Next: A Long Season Starts With Questions
The Celtics will look to regroup quickly, with the Robinson ankle situation looming over everything. If the center is sidelined, Boston’s frontcourt rotation gets thin in a hurry, and the double-big looks that worked in the first half disappear. Tatum’s continued climb back — he returned from a torn Achilles toward the end of last season and showed flashes Tuesday of a player rounding into form a full year removed from the injury — remains the season’s most important variable. His 10-assist night, even in a loss, was a reminder of how complete his game has become.
George, meanwhile, gave Boston everything it could have asked for in game one and then some. The debut record, the all-time three-point climb, the two-way flashes — if he sustains anything close to that level, the Brown trade will look visionary. The challenge is the other 81 games, and a 36-year-old body holding up through them.
Detroit, for its part, gets to savor this one. Opening-night comebacks from 22 down do not happen by accident; they happen when a team refuses to fold. The Pistons believed they were the East’s best team last season, and on Tuesday afternoon in front of their home crowd, they played like it when it mattered most. The rest of the conference has been put on notice.
