Best of NBA: Cavaliers win thriller after Celtics' Hayward goes down with injury

CLEVELAND -- Boston's Gordon Hayward broke his left ankle just five minutes into the season, a grisly injury that overshadowed Kyrie Irving's return to Cleveland and the Cavaliers' 102-99 win over the shocked Celtics on Tuesday night.

LeBron James scored 29 points -- 13 in the fourth quarter -- in his most extensive action in three weeks because of a sprained left ankle. He also fed Kevin Love for a critical 3-pointer with 46.3 second left to put the Cavs up 102-98.

Irving, who asked to be traded this summer after six seasons in Cleveland, had a chance to tie it with a 3-pointer at the horn but missed. Irving then shared a warm embrace with James, his teammate for three seasons.

Irving finished with 22 points for the Celtics, who overcame an 18-point deficit in the third and led with 2:04 left.

Love had 15 and Derrick Rose 14 in his debut for the Cavs (see full recap).

Rockets rally to spoil ring night for Warriors
OAKLAND, California -- Kevin Durant's baseline jumper swished through the net just barely too late, and the Houston Rockets rallied in the fourth to beat Golden State 122-121 Tuesday on the night the Warriors received their championship rings.

The Warriors had one last chance with 10.6 seconds left and Durant came up with the ball after Stephen Curry had missed. Durant and the Warriors thought they'd won and confetti began to fall when the two remaining officials -- the third got hurt in the fourth quarter -- reviewed the play and said Durant's shot was after the buzzer.

Trevor Ariza's 3-pointer with 2:09 remaining pulled Houston within 119-118 then Patrick McCaw hit a baseline jumper immediately after Golden State's timeout. James Harden made a layup and PJ Tucker hit two free throws with 44.1 to make it 122-121.

Nick Young came off the bench to hit six 3-pointers and score 23 points in a brilliant Warriors debut, Curry scored 22 points and Durant had 20 after a slow start. Klay Thompson added 16 points.

Chris Paul had four points on 2-for-9 shooting in his Rockets debut, while Harden scored 27 points and Eric Gordon 24 for the Rockets. Houston opened the fourth with a 9-0 run to get back in it (see full recap).
