Marcus Smart lost his cool a bit Tuesday night during the Celtics’ game against the Wizards.
Smart was seen on the bench with under a minute left as the team trailed by 13 having a heated argument with two assistant coaches.
The argument never became physical, but Smart was slamming his towel screaming at the assistants, who were also animated.
One assistant then stood in front of Smart, as if to make sure things did not escalate.
Smart apologized for the incident after the game.
“To my coaching staff and my teammates and the Celtics organization- I apologize for my actions tonight,” he wrote in a tweet. “In hating to lose, my actions were childish and unprofessional and never under any circumstances do I have the right to act that way and for that I sincerely apologize. I’m a role model to kids and a player for Coach. I’m sorry.”
Smart finished the game with 13 points on 4 of 13 shooting in the 123-108 loss.
