Cleveland Cavaliers forward Kevin Love has claimed that Kelly Olynyk injured his arm on purpose in his side's clash against the Boston Celtics in the NBA playoffs.

The 26-year-old sustained a dislocated shoulder in the incident in the first quarter as Olynyk clamped down on his arm and appeared to tug.

The Cavaliers have revealed that Love will undergo further tests in the next 24 hours to reveal the severity of the problem, but the forward has pointed the blame firmly at the Celtics man.

"I thought it was a bush-league play," Love told reporters. "I have no doubt in my mind that he did it on purpose."

Cleveland won the game 101-93 to take their series against the Celtics 4-0 and advance to the Eastern Conference semi-finals.
