The clip of Irving stomping his left foot on the Celtic's Lucky the Leprechaun logo made its rounds on social media and came about after a Celtics fan had been arrested for allegedly throwing a plastic water bottle at Irving during the game.

Following the Nets' Game 4 playoffs win, a water bottle was thrown as the Brooklyn-based team exited the arena via the tunnel for the locker room, barely missing Irving's head.

Reacting immediately, teammate Tyler Johnson began yelling at the crowd in the direction the bottle was thrown from. The incident was caught on camera and shared to social media.

A spokesperson for TD Garden said the suspect may now be banned from the venue for life. "We have zero tolerance for violations of our guest code of conduct, and the guest is subject to a lifetime ban from TD Garden," the official said, per NBC Boston.

After the game, Irving told the press that "underlying racism" was to blame for the incident.

"It's unfortunate that sports has come to a lot of this kind of crossroad where you're seeing a lot of old ways come up," the point guard said. "It's been that way in history in terms of entertainment and performers and sports for a long period of time. It's just underlying racism and treating people like they're in a human zoo – throwing stuff at people, saying things. There's a certain point where it gets to be too much."
