The Cleveland Cavaliers and their topsy-turvy season continued after going down to the Atlanta Hawks, while Russell Westbrook's record bid was put on hold for another game.
Reigning NBA champions the Cavaliers suffered a 114-100 defeat to the Hawks in Cleveland on Friday.
Westbrook failed to break Oscar Robertson's single-season record for most triple-doubles after the Oklahoma City Thunder lost 120-99 to the Phoenix Suns.
The San Antonio Spurs defeated the Dallas Mavericks 102-89, while the Houston Rockets were beaten by the Detroit Pistons.
CAVS STUMBLING INTO PLAYOFFS
The Cavaliers had the chance to move closer to securing the top seed in the Eastern Conference but they blew it.
After topping the Boston Celtics on Thursday, the Cavs came crashing back down to earth as Tim Hardaway Jr. scored 15 of his 22 points in the fourth quarter.
LeBron James posted 27 points for the Cavs, who came unstuck against a Hawks team missing Dwight Howard, Paul Millsap, Kent Bazemore and Dennis Schroder.
WESTBROOK HAS TO WAIT FOR RECORD
The Thunder guard finished with 23 points and 12 rebounds, but eight assists as his teammates missed several shots after getting a dish from their MVP candidate.
While Westbrook failed to break a tie with Hall of Fame guard Oscar Robertson for most triple-doubles in a season, he did join him as the only players in NBA history to average a triple-double for an entire season.
Westbrook entered Friday's game needing six assists to ensure he would have at least a 10-assist average.
SPURS RESERVES STAR
Tony Parker did not come off the bench as Manu Ginobili and Kawhi Leonard stayed home in San Antonio.
Bryn Forbes starred with a career-high 27 points for the Spurs, who have consecutive 60-win seasons for the first time in franchise history.
