DENVER -- Raymond Felton's driving layup with 1.5 seconds left gave the Dallas Mavericks a 144-143 double-overtime victory on Friday night over the Denver Nuggets.

Denver's Kenneth Faried missed a hook shot in the lane over Felton as time expired.

Dallas, which is locked into the seventh seed in the Western Conference, pulled its starters at the start of the second overtime. Dallas also rested guard Rajon Rondo for the whole game.

Denver's Danilo Gallinari scored a career-high 47 points, including 17 in the two overtimes. It was the most by a Nugget since Carmelo Anthony had 50 on Feb. 7, 2011.

Six Nuggets scored in double figures, as did seven Mavericks. The previous high for points in an NBA game this year was Dallas, which had 140 against the Lakers in November.

Dirk Nowitzki scored 25 points and Richard Jefferson added a season-high 24 as Dallas withstood Denver's furious second-half rally.

The Nuggets played sloppy and lethargically in the first half, allowing Dallas to score 73 points and shoot 63 percent from the field. The Mavericks led by 21, 73-52 at the break.

Dallas led by as many as 23 points late in the second quarter before Denver awakened in the third quarter. The Nuggets used a 22-5 run in the quarter and pulled to within 93-89 by its end.

It was the first double-overtime game in Denver since December 20, 2007, when the Nuggets beat Houston.

NOTES: Former Nuggets coach George Karl returns Sunday to Denver when Sacramento comes to town. The Kings hired Karl in February, and this will be his first trip to Denver with a new team since being fired as Nuggets coach in 2013. From 2004 to 2013, Karl coached the Nuggets to nine playoffs and a 423-257 record. Denver fired Karl in the spring of 2013 shortly after he was named NBA coach of the year. "I can't wait to be able to sit down and chat with him prior to the game," said Nuggets interim coach Melvin Hunt, who was an assistant in Denver under Karl. "I know he'll have some insightful thing -- some insightful nugget -- to throw out there for us." ... Nuggets G Jameer Nelson (right flexor strain) did not play. F Darrell Arthur (right calf strain) dressed in uniform, but Hunt did not play to play him. ... Dallas will be the seventh seed in the upcoming Western Conference playoffs, but the second spot is up for grabs among Memphis, Houston, San Antonio and the Los Angeles Clippers. Mavericks coach Rick Carlisle is eager to see whom they'll face. “This is something that could come down to the last minute." ... Dallas forward Chandler Parson (right knee) did not play.
