Joe Mazzulla did not like it when Immanuel Quickley celebrated in front of their bench after converting a three-point shot in the second quarter, and the NBA fans saw the Boston Celtics head coach sending an NSFW message to the Toronto Raptors guard.

“Shut the f**k up,” Mazzulla told Quickley, who was taunting the Boston Celtics when a timeout was called.
In the past few years, Mazzulla has endeared himself to NBA fans with his no-nonsense and borderline-psycho approach to coaching. The Boston Celtics are preparing for their third full season under the 37-year-old tactician.

In the end, Boston got the last laugh, as they won 110-108 last night. Xavier Tillman hit the game-winning floater with 0.8 left on the clock to make it 2-1 in the preseason for the 18-time NBA champions.
Boston Celtics News: Jaylen Brown has fans worried with latest leg injury
NBA fans collectively held their breath when Jaylen Brown limped out of last night’s game due to a hamstring injury. However, according to head coach Joe Mazzulla, the former Finals MVP’s knock is not that serious.

“He’ll be okay. I talked to him after, he said he’ll be fine,” Mazzulla said via Noa Dalzell of SB Nation.
The Boston Celtics are handling Brown with kid gloves, as he’s expected to be the team’s No. 1 option this season sans Jayson Tatum. Against the Toronto Raptors, the 28-year-old guard had seven points, two rebounds, and one steal on 2-for-4 shooting from the field in seven minutes.
