BOSTON >> LeBron James scored 27 points and the Cleveland Cavaliers overcame a shoulder injury to Kevin Love to complete a first-round sweep of the Boston Celtics with a 101-93 victory Sunday.

Love left the court in the first quarter after hurting his left shoulder, and J.R. Smith was ejected for swinging his arm at Jae Crowder, but the Cavaliers held on to win a series for the first time since 2010, before James left for Miami.

Now Cleveland gets extra time before facing the winner of the Chicago-Milwaukee series. The Bulls lead 3-1.

The Cavaliers led 99-89 with 44 seconds left, but the Celtics didn’t give up. Isaiah Thomas hit a layup and Avery Bradley sank two free throws to cut the lead to six before the ball went out of bounds off Kyrie Irving. But Gigi Datome missed a 3-pointer before Irving was fouled and made two shots.
