Leonard, 29, said the slur while playing “Call Of Duty: Warzone” on his Twitch channel: “Fing cowards, don’t fing snipe me, you fing k b****.”

Leonard has about 70,000 Twitch followers. This comes two months after he tweeted to his 177,000 Twitter followers that he stands against “bigotry, racism, and hate.”

Leonard issued a statement Tuesday night saying he didn’t understand the meaning of the word, and he made his apology.

“I am deeply sorry for using an anti-Semitic slur during a livestream yesterday,” Leonard wrote on Instagram. “While I didn’t know what the word meant at the time, my ignorance about its history and how offensive it is to the Jewish community is absolutely not an excuse and I was just wrong. I am now more aware of its meaning and I am committed to properly seeking out people who can help educate me about this type of hate and how we can fight it.

“I acknowledge and own my mistake and there’s no running from something like this that is so hurtful to someone else. This is not a proper representation of who I am and I want to apologize to the Arisons, my teammates, coaches, front office, and everyone associated with the Miami Heat organization, to my family, to our loyal fans and to others in the Jewish community who I have hurt. I promise to do better and know that my future actions will be more powerful than my use of this word.”

Regardless of apology, the Miami Heat issued a statement Tuesday night that said the organization condemns Leonard’s remarks, and they said the player will be away from al team activities “indefinitely.”

Tuesday afternoon, the NBA released a statement that said it was aware of Leonard’s remarks, and that they were “in the process of gathering more information,” saying, “The NBA unequivocally condemns all forms of hate speech.”

Leonard, in his ninth NBA season, has only appeared in three games this season. The 7-foot center from Illinois had a season-ending shoulder injury in January, and he will be a free agent at the end of this season. Leonard has averaged just nine minutes and three points in his short stint this season.

The Miami Heat are currently on break and will resume play Thursday against the Orlando Magic.

Leonard was a first-round pick in 2012 by the Portland Trailblazers. He has been known to enjoy banter with fans while playing video games online.
