Kyrie Irving had 11 of his 16 points in the fourth quarter, including two free throws that put Boston ahead in the closing seconds, and the Celtics beat the Golden State Warriors 92-88 on Thursday night for their 14th straight victory.
Jaylen Brown had 22 points and seven rebounds, and Al Horford added 18 points and 11 rebounds.
Kevin Durant has 24 points for Golden State. The defending champion Warriors had won seven in a row.
Playing his second game since suffering a facial fracture, Irving shed his protective mask in the second quarter. Then, with the game tied at 88, he was fouled on his layup attempt and calmly made a pair of free throws. Durant then came up empty on his jumper on the other end.
Golden State led by as many as 17, but had to lean heavily on its reserves as its trio of Stephen Curry, Klay Thompson and Durant struggled offensively.
Curry, who returned to action after missing a game with a bruised right thigh, was the most ineffective. He was 3 of 14 from the field — 2 of 9 from the 3-point line — and had nine points.
