The incident occurred during a timeout with 7 minutes 12 seconds left in the second quarter. In a video posted on Instagram by a fan who was sitting behind Boston’s bench, Morris is seen shoving Brown with two hands. Brown did not react, and teammates quickly got between them before the situation escalated further.

MIAMI — Celtics president of basketball operations Danny Ainge said he is not concerned about the minor altercation involving Marcus Morris and Jaylen Brown in the second quarter of Boston’s loss to the Heat Thursday.


“It’s two good kids that are competitive,” Ainge said by phone from Boston Friday. “They both want the same thing. Emotions happen in games, and I’m not worried about it.”

It appeared Morris had become frustrated by Brown’s lack of effort during a play that preceded the timeout. Brown missed a pair of shots inside, and then slowly jogged back as the Heat quickly attacked for an easy basket. Morris looked at Brown and clapped his hands at him in frustration.

Both players had left the locker room Thursday before the video began to circulate.

“I have not talked with them about it and haven’t really heard anything from anyone about it,” Ainge said, “so I don’t really feel a need to intervene.”
