L2M report says CC:
During his attempt to tie up the ball, Stephenson (IND) wraps his arms around Green's (CLE) head/neck and commits a foul. Since the foul precedes a potential jump ball, the foul takes precedence and is correctly called. Referees use replay to confirm that no hostile act occurred during the dead ball situation.
