Marcus Smart and Jaylen Brown went at it in the Boston Celtics' locker room after the Celtics blew a 17-point lead against the Miami Heat in Game 2 of the Eastern Conference Finals, according to Shams Charania of The Athletic.

Soon after the Celtics' loss, loud noises could be heard coming from the locker room, with Smart's voice coming through loud and clear to the media outside. Charania paints the picture of what happened and how Brown got involved with Smart:

Sources told The Athletic that Smart stormed into the Celtics postgame locker room saying that other players needed to be held accountable and not simply point the finger toward him when things are going wrong. As Smart continued and his voice grew louder, sources said Brown snapped back and shouted that Celtics players must stay together and that their actions must come as a team, not individually, and that Smart needed to cool off. Those sources added Smart had verbal exchanges with a couple of the assistant coaches during the game.

Smart and Brown had a tense interaction inside the locker room, with objects thrown around. Teammates diffused the situation before any physical altercation could take place, sources told The Athletic.

Smart and Brown have reportedly smoothed over the tensions, and the Celtics are prepared to learn from what happened as they get ready for Game 3 on Saturday. Brown spoke to the media afterward on Thursday night and downplayed what happened in the locker room, even praising Smart's fire and passion.

The Celtics may be down 2-0 in the series, but this series is far from over. Boston has looked like the better team for good chunks of the series so far, only for Miami to never quit and make more big plays in crunch time. The Celtics might be getting Gordon Hayward back from an ankle injury in Game 3, which would provide a nice boost.

Furthermore, the last two Eastern Conference champions have come back from 2-0 deficits, so don't count Boston out just yet.
