The Philadelphia 76ers lost Ben Simmons to injury in another NBA road defeat on Saturday, while the Miami Heat paid tribute to Dwyane Wade.
Simmons left a 119-98 loss to the Milwaukee Bucks in the first quarter after aggravating an existing back problem and will reportedly undergo an MRI on Sunday.
Giannis Antetokounmpo relished his fellow All-Star's absence, putting up 31 points and 17 rebounds in a double-double that condemned Philadelphia to a sixth successive away loss.
The 76ers (35-22) sit fifth in the Eastern Conference, one place behind the Heat (36-20) following their 124-105 victory over the Cleveland Cavaliers.
The win added to a memorable occasion as Miami welcomed former favourite Wade back to AmericanAirlines Arena, officially retiring the number three jersey he wore during the team's NBA championships in 2006, 2012 and 2013.
Wade, 38, retired at the end of last season after returning to the Heat for his career swansong.
Harden hot in valuable Houston victory
James Harden hit a game-high 38 points while Russell Westbrook went 14-of-26 for 34 points as the Houston Rockets topped the Utah Jazz 120-110.
The Jazz struggled to handle Houston's small-ball approach and are now level with the Rockets at 36-20.
Kawhi Leonard tallied 31 points and eight rebounds but the Los Angeles Clippers lost for the third time in as many games, going down to the Sacramento Kings 112-103.
Meanwhile, the Atlanta Hawks overcame a nine-point deficit at the start of the fourth quarter to beat the Dallas Mavericks 111-107.
Trae Young and John Collins each recorded double-doubles to inspire the Hawks to their 17th win of a lean campaign.
Kawhi a lone performer for cold Clippers
Leonard did his part against the Kings at Staples Center but the reigning MVP had little help from his fellow Clippers starters, all of whom failed to reach double figures for points.
Reggie Jackson and Landry Shamet were particularly culpable, the pair making just three of their combined 12 three-point attempts.
Bam drops the hammer
