The NBA fined Boston Celtics star Paul George $2,000 for flopping during the Celtics’ 121-113 season-opening loss to the Detroit Pistons on Tuesday night, the league announced Wednesday.

“BOS’s Paul George was assessed a postgame Flopping fine of $2,000 upon league office review,” the NBA said in its announcement. The play under review came with about three minutes remaining in regulation, when George bumped Pistons guard Duncan Robinson in transition and went down hard despite light contact.

The penalty adds an unusual footnote to an otherwise historic debut. George scored 38 points in his first regular-season game with Boston, setting a franchise record for points scored in a Celtics debut. He shot 12-of-21 from the field and 7-of-12 from three-point range, adding five rebounds, three assists and five steals. He became just the sixth player in NBA history to record at least 38 points, five rebounds, five steals and seven made three-pointers in a single game.

George’s big night was spoiled by Boston’s collapse. The Celtics led Detroit by as many as 22 points before the Pistons stormed back with a 28-3 fourth-quarter surge to win 121-113. Cade Cunningham and Jalen Duren scored 22 points apiece for Detroit, while Duncan Robinson scored 21, including 15 in the fourth quarter.

George joined the Celtics this offseason in a trade with the Philadelphia 76ers. Under the NBA’s flopping rules, the league office can assess penalties after reviewing game footage even when officials do not call a violation during the game, with fines escalating for repeat offenders. The $2,000 fine does not include a suspension and does not affect George’s availability for Boston’s next game.
