11:07 AM PT -- 6/2 -- Cole Buckley -- the 21-year-old fan who allegedly threw a water bottle at Kyrie Irving -- appeared at Boston Municipal Court on Wednesday for his arraignment ... and was ordered to stay away from the TD Garden.
Buckley entered a not guilty plea for assault and battery with a dangerous weapon ... and was silent as he left the courthouse.
Suffolk County DA Rachael Rollins spoke with reporters about the case ... saying, "It is not lost on me that he chose to do this in a sport that is overwhelmingly Black men," according to reporter Juliana Mazza.
"We are not going to allow this trend to continue. Period. End of story. We have not charged him with a race-based hate crime or civil rights violation, but you don’t get to behave this way."
Buckley is due back in court in August.
Kyrie Irving was the target of another idiot fan Sunday night who almost beaned the b-baller in the head with a water bottle ... and this time the culprit was arrested.

Irving said after the incident ... "You're seeing a lot of old ways come up... just underlying racism and treating people like they're in a human zoo. Throwing stuff at people, saying things. There is a certain point where it gets to be too much."
Kevin Durant also chimed in ... “Have some respect for the human beings and have some respect for yourself. Your mother wouldn’t be proud of you throwing water bottles at basketball players or spitting on players or tossing popcorn,” Durant said. “So grow the f**k up and enjoy the game. It's bigger than you."
