"Violence is never the answer, but sometimes it is," Barnes said. "And unfortunately, it happened. I don't regret it."
The Grizzlies' 103-95 victory over the Knicks on Saturday night at FedExForum was the first time Barnes and Fisher had met since an altercation at the California home of Barnes' estranged wife, Gloria Govan, in October. Barnes and Fisher are former friends and ex-Los Angeles Lakers teammates.
Barnes was reprimanded on Dec. 28 by the NBA, which imposed a two-game suspension on Barnes for attacking and threatening Fisher. The NBA Players Association filed a grievance to try to recoup lost salary during the two-game ban.
"Matt Barnes' comments condoning violence do not reflect who we are as a league or the character of our players," Kiki VanDeWeghe, the NBA's executive vice president of basketball operations said Sunday in a statement. "His words are unacceptable and entirely inconsistent with the core principles of this game and the NBA."
Barnes told the New York Daily News on Thursday that he would not talk to Fisher when he saw him because "I don't talk to snakes." He also referred to Fisher as a "snitch."
"I just don't like him, plain and simple," said Barnes, who had five assists, nine rebounds and two points against the Knicks. "He knows I don't like him. Don't say nothing to me, I don't plan on saying nothing to him. Don't try to shake my hand. There's none of that. There's nothing there. There never will be. Just stay away from me basically."
When asked Saturday to comment on Barnes, Fisher declined.
"Look, man, we are here to play basketball," Fisher said. "This is about a basketball game, not about me and what happened. So if you have some basketball questions, that's what I'm here for. There is nothing to talk about. Decisions have been made. I say we move on."
