A Masshole Celtics fan has been banned from TD Garden for two years after he racially abused Golden State Warriors center DeMarcus Cousins during a game earlier this year, according to reports.

The fan called Cousins the N-word during the Warriors’ only trip to Boston this season, on Jan. 26, Yahoo Sports’ Chris Haynes reported Thursday night.

“I was told DeMarcus informed one of the team security guys and they got a hold of the security team there at TD Garden. They took care of the fan, but I was told that ultimately that fan was banned for the rest of this season and next year,” Haynes said.

A TD Garden rep told the Boston Globe that the ban was issued by the NBA.

It was unclear whether the ban applies to only Celtics games or all Garden events. The NBA and Celtics did not immediately respond to requests by the Globe for comment.

Neither Cousins nor the Warriors offered a statement about the matter.

But Cousins appeared to allude to the incident during a recent episode of Haynes’ “Posted Up” podcast in which the two discussed the fallout from a similar incident involving Oklahoma City Thunder guard Russell Westbrook and Utah Jazz fans.

The Jazz suspended the fans for heckling Westbrook with “degrading and offensive” language.

“Bro, I’ve been called n—-r,” Cousins told Haynes. “It’s happened to me on a few occasions. I reported to the league. I may have said whatever I said back, and I’m still punished for it.”
