Cleveland Cavaliers secured top spot in the Eastern Conference with a 135-113 victory over Chicago Bulls.
Victory means Kenny Atkinson's side will have home advantage in next week's play-offs following the completion of the regular season on Sunday.
Darius Garland top-scored with 38 points as the Cavaliers improved to 63-16 with three regular-season games remaining.
Elsewhere, Luka Doncic was ejected in the fourth quarter as Los Angeles Lakers lost 136-120 to Oklahoma City Thunder.
Doncic was dismissed for a second technical foul after an official said he was verbally abused by the Slovenian.
The 26-year-old insisted that he was responding to a courtside fan, but the decision stood.
Shai Gilgeous-Alexander top-scored with 42 points for Thunder, who have already secured top spot in the Western Conference.
Lakers need two wins from their remaining three regular-season games to guarantee third place.
Just behind the Lakers in fourth are LA Clippers, who earned a fifth successive win by beating San Antonio Spurs 122-117.
Clippers have the same 47-32 record as Denver Nuggets, Golden State Warriors and Memphis Grizzlies, but are ahead courtesy of NBA tiebreaker rules.
Warriors occupy the final play-off position in sixth after beating Phoenix Suns 133-95. Grizzlies are seventh after winning 124-100 at Charlotte Hornets.
