In the waning moments of Game 5 against the Miami Heat, Indiana Pacers guard Lance Stephenson received an elbow to the throat from Dexter Pittman, sending him to the floor. Stephenson was evaluated after the game for a concussion and received X-rays, according to Alex Kennedy of Hoops World:
Doctors are evaluating Lance Stephenson. He's getting x-rays and a concussion test. He may have a broken collarbone, says Danny Granger.— Alex Kennedy (@AlexKennedyNBA) May 23, 2012
Stephenson landed awkwardly after the elbow sent him up into the air. As he came back down, he was able to extend his left arm out for support, but the force of that impact certainly could have led to a broken collarbone.
Pittman, who winked in reaction to the event, is likely to receive a significant suspension as a result of his actions.
