Dennis Schroder scored 27 points, Dwight Howard added 16 points and 22 rebounds, and the Atlanta Hawks took advantage of Carmelo Anthony's second-quarter ejection to beat the Knicks 102-98 in overtime on Wednesday night.
Derrick Rose finished with 26 points for New York, but the star point guard fell as he was dribbling near the Knicks' basket and lost his footing with 6 seconds left in overtime and Atlanta leading by one.
Schroder followed with a pair of free throws to make it 100-97. Kristaps Porzingis, who scored 24 points, was fouled as he shot a 3-pointer on the ensuing possession, but he made just one of three free throws to end the suspense.
The Hawks had lost three straight and six of seven at home. They are just 7-14 since beginning the season 9-2.
Atlanta didn't trail again in overtime after Thabo Sefolosha hit a 3 to make it 89-88 with 3:54 left.
In the closing seconds of regulation, Rose and Schroder both missed a potential game-winning jumper.
It was a chippy, emotional night by both teams, but the most dramatic moment came with 3:08 remaining in the second.
Anthony and Sefolosha were tied up near the basket, positioned for a rebound, when the Knicks star seemed to lose his cool with a forearm jab.
The two players exchanged heated words and were separated. Players and assistant coaches on both benches stood up, and security personnel for each team came onto the floor.
Anthony, a nine-time All-Star, followed Sefolosha to the Hawks' end of the floor, but the situation calmed down. Anthony left with 10 points in 15 minutes and Atlanta leading 43-38.
In the third, Rose was driving for a layup and was fouled by Howard, who was cited for a flagrant 1. Replays showed that Kent Bazemore, not Howard, likely should've been whistled.
Midway through the fourth, Schroder drove for a fast-break layup and was fouled hard to the floor by Porzingis, but there was no video review.
Knicks coach Jeff Hornacek was called for a technical in overtime when Paul Millsap wasn't whistled for an offensive foul against Porzingis.
Knicks G Courtney Lee, the team's fourth-leading scorer with 10 points per game, did not dress because of a sore right wrist.
An MRI showed nothing broken, but Lee said he felt his fingers and knuckles crack when he was injured early in a home loss Sunday to Boston.
Lee had hoped not to miss a game after playing 34 minutes and scoring 11 points against the Celtics, but three days later, he felt too much discomfort in the morning shootaround.
Sasha Vujacic started in Lee's spot and scored two points on 1-for-7 shooting.
