In Game 2 of the Eastern Conference Finals between the Boston Celtics and Cleveland Cavaliers, J.R. Smith shoved Al Horford.

It was the fourth quarter, with the Celtics leading and Horford attempting to put in a an alley-oop attempt, then it happened — J.R. Smith shoved the (then) vulnerable big in the back.

Here is the beautiful bean footage:

Depending on your fan allegiance, if you have any, that was either the dirtiest play in the history of the sport, a ghost call by the referees, or just part of the game.

As you can tell with the video, at that juncture of the game, the Celtics were starting to pull away from a Cavaliers squad that faltered mightily after the half. Some of this could be caused by how LeBron James went out with an injury, then quickly returning but never being the same, but that's purely conjecture at this point.

Oddly enough, after Smith shoved Al Horford, Marcus Smart lost his marbles and began to jaw at the Cavs rotational guard — with the officials having to slow his roll and escort him off the hardwood.

After reviewing the monitor, the refs decided that only a Flagrant 1 happened, not resulting in anything too crazy other than a few shots from the charity stripe and the ball.

Boston would win Game 2, taking a rather large 2-0 lead in the Western Conference Finals.
