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. 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. “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.”
