Knicks coach Derek Fisher was involved in an altercation with Memphis Grizzlies forward and former teammate Matt Barnes in California on Saturday, a person with knowledge of the details said.
The New York Post, citing an anonymous source, reported Wednesday that the altercation was because Fisher is dating Barnes' estranged wife. Fisher filed for divorce from his wife, Candace, in March.
Barnes played basketball for Del Campo High School in Fair Oaks and UCLA.

The person said Fisher traveled to Los Angeles after practice Saturday to see his children and the altercation happened that night while Fisher was attending a gathering at the home of Gloria Govan, Barnes' estranged wife. The person spoke to The Associated Press on condition of anonymity because no comments were authorized.
Fisher missed practice Monday — the team announced at the time it was for personal reasons — and led the Knicks in their exhibition opener Wednesday night against a Brazilian club team.
"My state of mind is that we have a game tonight and nothing that I've experienced has anything to do with how we perform tonight," Fisher said before the game, adding that he was "completely focused and committed to the team."
"I'm not distracted in any way," he said.
Fisher and Barnes were teammates with the Los Angeles Lakers from 2010-12. The Grizzlies held training camp last week in Santa Barbara, California, and the Post reported that Barnes drove to Govan's home when he learned that Fisher was there.
"We are aware and currently gathering information regarding today's report involving Matt Barnes," the Grizzlies said in a statement. "We have no further comment at this time."
An NBA spokesman said it would be premature to comment. Asked if he thought there could be legal ramifications, Fisher said: "I guess we'll see."
Fisher said he told his players about the situation when he gathered them before the game because he wanted them to hear about it from him directly.
"I'm here, I'm focused," he said. "It's not something that's going to take me away from who we are or what we're trying to do and I assured them of that."
Knicks All-Star Carmelo Anthony said the Knicks were caught off guard by the news.
"Nobody really knew kind of what was going on — still nobody knows the details of what's happening," Anthony said. "So as a team it was just amongst us to kind of just let him deal with his own personal issues and us, when we come in here and it's time to play basketball, we deal with that."
Fisher is in his second season with the Knicks after spending most of his playing career in Los Angeles, where his children remain. He said his family decision should show his commitment to his job in New York.
"So as far as that goes, the guys are the ones that ultimately know who I am and what I'm about. They see me every day," Fisher said.
"If guys feel like I'm not here or not focused, they'll find that out. But at this point I don't think that's an issue."
