Knicks coach in altercation over ex-player’s wife

NEW YORK—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.

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.
