Detroit beat Boston 121-113 at Little Caesars Arena on Tuesday, Oct. 20, 2026, in the first game of the 2026-27 NBA season.
The sharpest detail is the size of the hole: Detroit trailed by 22 points, with Boston leading 72-50 early in the third quarter, before a 23-0 fourth quarter run flipped the opener.
George Makes Celtics Debut History In A Loss
Paul George scored 38 points in his Celtics debut, the most by a player in a Celtics debut, on 12 of 21 shooting and 7 of 12 from three, with five steals. Boston acquired him from Philadelphia in the trade that sent Jaylen Brown to the 76ers, and for two and a half quarters the debut looked like a statement game. Boston built its biggest lead at 72-50 early in the third quarter, with George scoring from every level and the Celtics defence turning Detroit over into transition chances.
George was candid afterward about still finding his conditioning early in the season:
“Getting back into the swing of things. Playing again. I thought, really, the camp, legs were just heavy. I was winded a lot of times, so it was taking away the ability to kind of do things when I just felt a little heavy and sluggish. But I’m getting my wind back.” Paul George, Boston Celtics, postgame, published by Bleacher Report
That honesty frames the fourth quarter fairly. George’s debut scoring record stands, and Boston will build on his shot making. But a heavy legged star, a bench unit that lost its rhythm, and a home crowd that woke up all arrived at the same time, and Detroit was ready to take advantage of every one of those factors in the final period.
Green Sparks A 23-0 Fourth Quarter Run
Javonte Green did not play in the first half. He scored 19 points off the bench with five three pointers, sparking the comeback that decided the game. Around him, Cade Cunningham and Jalen Duren each scored 22 points, Cunningham with eight assists and Duren with nine rebounds, while Duncan Robinson added 21. Detroit’s 23-0 run in the fourth quarter did not just erase a lead, it changed who controlled every possession, with Boston rushing shots and Detroit playing through Cunningham with a lead to protect in the closing minutes.
Jayson Tatum scored 13 points on 6 of 23 shooting, going 0 for 7 from three, with 11 assists for Boston, in his first full season since tearing his Achilles tendon in May 2025. His playmaking was there, his shot was not, and on a matinee tipoff across the river from Windsor, the Canadian audience watching the league’s first game of the season saw a reminder that opening day rewards the team that finds its legs last, not first. Detroit found Cunningham, Duren and an unlikely bench hero. Boston found a debut record and a lesson.

An Opener That Sets Up Both Teams Honestly

The regular season version, played just across the border in Detroit, offered a sharper story. It also connects to Toronto’s own reshaped roster, covered in Leonard Returns In Raptors Rout Of Knicks, because the Eastern Conference these Pistons and Celtics are chasing now runs through several rebuilt contenders at once.
For Detroit, the win is a proof of depth: a starter level night from Cunningham and Duren, 21 from Robinson, and a comeback lit by a player who did not touch the floor before halftime. For Boston, George’s 38 point debut says the ceiling is real, while a 23-0 fourth quarter run against says the rotation still has work to do. One game proves little over 82, but as season openers go, this one gave both teams a clear picture of themselves.
