NBA roundup: Nikola Jokic bags triple-double as Nuggets down Celtics in thrilling showdown
The eagerly anticipated clash between the reigning NBA champions and Eastern Conference-leading Celtics lived up to the billing in a hard-fought duel in Denver.
Denver talisman Jokic finished with 32 points, 12 rebounds and 11 assists while Jamal Murray finished with 19 points and Aaron Gordon 16.
The win gave Denver a clean sweep over Boston in their meetings this season.
The Celtics, beaten by Cleveland on Tuesday, suffered back-to-back losses for the first time since early November.
Jokic meanwhile played down the significance of the result, brushing off suggestions that Thursday's showdown could be a preview of the NBA Finals.
"We're a long way from the finals my friend," the Serbian said in an on-court interview after the win.
"We had a really good energy tonight...our offence was really clicking today."
Boston meanwhile were left to reflect on a loss that came despite a 41-point performance from Jaylen Brown, who shot 16-of-29 from the field.
Kristaps Porzingis added 24 points but Jayson Tatum was restricted to 15 points.
Celtics coach Joe Mazzulla said his team's 12 turnovers had been the difference.
"When you play against another great team, those 10-12 possessions are super, super critical," Mazzulla said. "I think Denver did a better job of taking advantage of those than we did."
Boston remain on top of the Eastern Conference with a 48-14 record. Denver meanwhile are third in the West at 43-20, one game back from leaders Minnesota.
In other games on Thursday, Luka Doncic completed a triple-double to help the Dallas Mavericks edge past the Miami Heat 114-108.

The Mavs trailed 101-100 with just over four minutes remaining but pulled clear to clinch victory after a flurry of late three-pointers.

Dallas improved to 35-28 with the win to remain in playoff contention in the Western Conference.
In Indianapolis meanwhile, the Minnesota Timberwolves snatched a 113-111 win over the Indiana Pacers thanks to a 44-point performance from Anthony Edwards in a see-saw battle that saw the lead change hands 17 times.
