After the Boston Celtics blew a second straight second-half lead and lost 106-101 to the Miami Heat on Thursday night, Celtics guard Marcus Smart was yelling at his teammates in the locker room before leaving the room swearing, according to ESPN’s Malika Andrews.

Smart left the locker room yelling, “Y’all on some bulls—,” according to Andrews, and there were several loud clanks — like someone throwing things — coming from inside it, while several players, beyond just Smart, were yelling.

Though Smart left without speaking to reporters after being requested following Game 2 of the NBA Eastern Conference finals, those who did speak — Celtics coach Brad Stevens, guards Kemba Walker and Jaylen Brown, and forward Jayson Tatum — all tried to downplay the situation.

“It was nothing,” Walker said. “It was nothing.”

“Guys were emotional after a hard game,” Stevens said. “Hard loss.”

“It really just, a lot of emotions just flying around,” Brown said. “Obviously we feel like we could have won, we should have won, but we didn’t. So just a lot of emotions flying around. That’s it.”

“I don’t know who said that,” Tatum said. “I mean, we’re 0-2. I mean, we’re frustrated, but this is team sports.

“We’re not supposed to be happy we’re down 0-2, but nothing out of the ordinary, just talking about the game. It’s cool. Got to get ready for the next one.”

To do that, the Celtics will have to figure out what happened to them in the fourth quarter of Game 1 and the third quarter of Game 2 — both of which saw Boston cough up double-digit leads (14 points in Game 1, and 15 in Game 2). Boston was outscored 37-17 in the third quarter Thursday night, disintegrating in a hail of missed shots and ugly turnovers.
