NEW YORK -- Kristaps Porzingis' dunk wasn't spectacular, certainly nothing like Giannis Antetokounmpo jumping over Tim Hardaway Jr. for a slam.
But the moment he landed, punching the court in pain , the Knicks' playoff hopes had likely crumpled right along with him.
Porzingis tore the ACL in his left knee Tuesday night in the Knicks' 103-89 loss to the Milwaukee Bucks.
Complete coverage of the Philadelphia 76ers and their rivals in the NBA from NBC Sports Philadelphia.
Antetokounmpo scored 23 points, jumping over Hardaway for one high-flying slam after Porzingis had dunked over him earlier in the game.
Porzingis crashed to the ground after his dunk with 8:46 left in the second quarter and was taken for an MRI exam that revealed his injury.
"More than a basketball player, he's my brother," Knicks center Enes Kanter said. "I don't want to see anyone going down like that hurting his knee. He's about to be an All-Star. I'm just going to pray for him tonight. He is the most important part of our family."
Eric Bledsoe also had 23 points and Khris Middleton added 20 for the Bucks, who are a season-high seven games over .500 (see full recap).

Reserve forward Marcus Morris also returned for Boston after sitting out two games because of a bruised left hip but the Celtics suffered their second-worst defeat of the season. Boston's only bigger loss was a 23-point defeat at Chicago on Dec. 11.

Magic overcome 21-point deficit vs. reeling Cavs
ORLANDO, Fla. -- Jonathon Simmons scored 22 of his career-high 34 points in the third quarter and the Orlando Magic overcame a 21-point deficit Tuesday night to beat the reeling Cleveland Cavaliers, 116-98.
The Cavaliers scored 43 points in the first quarter, but then went almost 6 1/2 minutes without scoring in the fourth and lost for the 14th time in 21 games. They played the second half without coach Tyronn Lue, who went to the locker room in the second quarter with what the team said was an illness.
The Magic made their first 10 shots of the second half and won consecutive games for the first time since Nov. 8-10.
LeBron James had 25 points, 10 rebounds and five assists for the Cavaliers, but did not have a rebound or an assist in a foul-plagued second half.
Evan Fournier scored 19 points for the Magic, who broke a nine-game home losing streak against Cleveland (see full recap).
