Hours after a crushing defeat to the Knicks, Sacramento Kings forward Matt Barnes choked a woman at a Manhattan night spot early Monday, law-enforcement sources said.

Police were called to the club Avenue in Chelsea at around 3:20 a.m. following Barnes’ alleged 3:20 a.m. attack on the 26-year-old victim, the sources said.

The woman, who was not identified, may be Barnes’ girlfriend — but his rep later suggested she was a stranger.

The NBA player — who has not been arrested — also allegedly “physically assaulted” another woman, 27, and a man, 35, from a table next to Barnes’ crew as they attempted to intervene.

They were both hit with a bottle, but it was not chucked by Barnes, the sources said.

Barnes’ initial beef was with people within his own crew of five to 10 pals at a club table before the fight escalated, the sources said.

“So they get into a fight amongst each other and it spills over to another group in close proximity,” a source said, adding that it’s unclear what sparked the dispute.

“Don’t know what sparked the dispute. This was a wild melee. This was a real good old fashioned barroom brawl.”

By the time officers arrived at the 10th Avenue club, Barnes and his buddies, including teammate DeMarcus Cousins, had left, sources said.

Barnes defend himself on Instagram Monday, posting, “There’s always two sides to a story.”

“The side the media consistently tries to paint of me . . . And what actually happened! Don’t believe everything you read,” Barnes posted to his more than 430,000 followers.

A rep for Barnes told TMZ that a woman, who was not identified as his girlfriend, had slapped him in the face after Barnes accidentally “butt bumped” her in the VIP section of the club and acted in self-defense when several men intervened.

Barnes was knocked to the ground and choked by one of the men, the rep said, according to TMZ. Cousins even jumped in to defend Barnes, the rep said.

Barnes’ lawyer, Alex Spiro, told The Post, “We believe no crime was committed and will continue to cooperate with the authorities.”

A video obtained by TMZ appears to show Barnes and Cousins outside of the club talking about the brawl. Cousins can be heard saying that Barnes “hit the sh-t out of this n—a.”

The fight came hours after Barnes stunk up Madison Square Garden, in the Kings’ 106-98 loss to the Knicks.

Barnes made just one of his 11 shots, and Sacramento was outscored by a whopping 21 points in the mere 17 minutes he was on the floor.

The 6-foot-7 Barnes is best known for a weird feud he had with former Knicks coach Derek Fisher – who once dated the player’s estranged wife, Gloria Govan, back in 2015. Barnes reportedly drove 95 miles to confront Fisher in Los Angeles for romancing Govan.

“We have clear standards of conduct and behavior expected of the entire Kings organization – on and off the court. We are working with all parties involved to gather information in order to take any appropriate next steps,” the Kings said in a statement.

The Kings are off until Wednesday, when they play at the Dallas Mavericks.
