Boston Celtics suffered a third consecutive loss (120-117 after overtime) against the New York Knicks, while Dallas won in Phoenix (99-95) without its superstar Luka Doncic, injured.
Among the Knicks, Julius Randle (37 points, 9 rebounds) and Jalen Brunson (29 points, 4 rebounds, 7 assists) were the stars of this win against the C's.
But it is above all the Massachusetts franchise that all eyes are on, after this third consecutive setback, a series that puts a strain on Boston, at the top of the Eastern Conference with 35 wins and 15 losses.
However, they did not disfigure Jayson Tatum (35 points, 14 rebounds) and Jaylen Brown (22 points, 9 rebounds).
The other surprise of the evening, in the East, came from Brooklyn, where the Nets were beaten by the Detroit Pistons (130-122), the team with the worst record in the conference (13 v., 37 s.).
The New York franchise is still without Kevin Durant, Ben Simmons went off the field early with a sore knee and Kyrie Irving's 40 points weren't enough.
In the Western Conference, Dallas (6th, 26th, 24th) could smile after the victory (99-95) against a direct rival, the Phoenix Suns (7th).
But the Mavericks had to do without their star, Luka Doncic, who sprained his ankle early in the game and never returned to the field.
In his absence, Spencer Dinwiddie had 36 points and 9 assists.
In Los Angeles, the Clippers, fifth in the standings, prevailed over the San Antonio Spurs (138-100), led by Paul George (35 points) and Kawhi Leonard (27).
