Russell Westbrook returned to his former home but the Houston Rockets fell to the Oklahoma City Thunder 113-92 in the NBA on Thursday.
Westbrook was dealt by the Thunder to the Rockets in the offseason after 11 years, an MVP and eight All-Star appearances with Oklahoma City.
The Rockets star was given a standing ovation as he returned to Oklahoma City for the first time since the trade, but the Thunder emerged victorious.
Westbrook had a game-high 34 points to lead the Rockets away from home, while Danilo Gallinari's 23 points and 11 rebounds fuelled the Thunder.
The Philadelphia 76ers overcame the absence of All-Star Joel Embiid to trump Eastern Conference rivals the Boston Celtics 109-98.
Embiid is set to undergo surgery on a torn ligament in a finger in his left hand, but the 76ers still managed to rally past the Celtics at Wells Fargo Center.
Josh Richardson posted 29 points as the 76ers overturned a double-digit deficit against the Celtics, who dropped their third straight.
Career night for Thompson as slumping Cavs snap streak
Tristan Thompson had a career-high 35 points and 14 rebounds as the lowly Cleveland Cavaliers rallied to snap a five-game losing streak by topping the Detroit Pistons 115-112 in overtime.
Harden fails to fire
James Harden scored 17 points but he was not at his usual best. The Rockets star was just five of 17 from the field and two of nine from three-point range.
Carmelo Anthony was limited to eight points as the Portland Trail Blazers lost 116-102 at the Minnesota Timberwolves. The veteran was three of 10 from the field, while he missed all three of his attempts from beyond the arc.
Westbrook returned to OKC as an opposition player but he was showered in love by the Thunder fans before and after the game.
