Cavs' Kevin Love injures shoulder

— -- BOSTON -- Cavaliers forward Kevin Love injured his left shoulder in the first quarter of Game 4 against the Celtics on Sunday and was ruled out for the rest of the game, which Cleveland won, 101-93, to sweep the first-round series.

Love was tangled up with Boston's Kelly Olynyk when the play occurred. Olynyk was called for a loose-ball foul with 5:22 remaining in the first quarter for clamping down on Love's left arm and pulling down, causing the injury. The seventh-year forward sprinted immediately to the Cavs' locker room while holding his shoulder after the contact.

The Cavs said Love will undergo icing and further evaluation on his shoulder.

Love had been averaging 18.3 points, 9.0 rebounds and 3.0 assists while shooting 47.1 percent from 3-point range during the Cavs' 3-0 start to the series.

Later in the first half, Cavs reserve big man Kendrick Perkins pushed Boston's Jae Crowder to the floor when setting a pick for LeBron James with 1:44 remaining in the second quarter.

On the ensuing fracas, Perkins appeared to jab Crowder in the face with his left fist. He and Crowder both received technical fouls.

After a referee's review, Perkins was assessed a flagrant 1 foul for the play.

Crowder was later injured on a flagrant foul by the Cavaliers' J.R. Smith, spraining his left knee after falling to the court on the play, in which Smith struck the Celtics forward in the face. Smith was ejected from the game.
