Miami star Dwyane Wade went down with a knee injury in the first half, and the Heat's playoff chances took another major blow with a 114-88 loss to the Cavaliers on Thursday night in Cleveland.
Wade suffered a bruised left knee in the first half and Miami didn't have the firepower to stop the Cavs, who got 23 points apiece from LeBron James and Kyrie Irving and won their 17th straight at home. James added eight rebounds and seven assists against his former team.
Tristan Thompson added 15 rebounds for Cleveland, a league-best 30-7 since Jan. 15.
The Heat dropped into a tie for eighth place with idle Boston in the Eastern Conference standings.
Earlier in the game, James moved into 20th place on the NBA's career scoring list, passing Hall of Famer Patrick Ewing.
James scored on a hook shot in the lane with 7 minutes, 22 seconds left in the first quarter, giving him 24,816 points. The 30-year-old has passed several prominent players this season, including Robert Parrish, Charles Barkley, Allen Iverson, and former teammate Ray Allen.
Next on the list is Jerry West with 25,192 points.
Los Angeles Lakers guard Wayne Ellington will miss the rest of the season with a separated right shoulder.
The Lakers made the announcement Thursday.
Ellington, an Episcopal Academy graduate, is the fifth player lost for the season by the Lakers, who have the NBA's fourth-worst record at 20-54. Los Angeles also is without Kobe Bryant, Steve Nash, Xavier Henry, and first-round pick Julius Randle.
Ellington was hurt in the fourth quarter of the Lakers' loss to New Orleans on Wednesday. He started 36 of his 65 games for Los Angeles this season, averaging 10.0 points, 3.2 rebounds, and 1.6 assists.
