Houston Rockets guard Kevin Porter Jr.’s girlfriend was left with a broken bone in her neck after the NBA player allegedly relentlessly beat and choked her at their Big Apple hotel, prosecutors said Wednesday — as he was released on $75,000 bail.

Porter, 23, is accused of repeatedly punching his 26-year-old girlfriend, Kysre Gondrezick, in the face and choking her until she couldn’t breathe inside their room at the four-star Millennium Hilton New York Hotel in Midtown early Monday, according to a criminal complaint.

The savage beatdown allegedly only stopped when Gondrezick — a former WNBA player — fled the room and was found bloodied and bruised by hotel employees in the hall, prosecutors said during Porter’s arraignment in Manhattan Criminal Court.

The pro baller, whose full name is Bryan Kevin Porter Jr., was arrested at about 6.30 a.m. Monday and charged with assault and strangulation after cops received a 911 call about the alleged attack.

His girlfriend told officers that Porter had struck her with a closed fist multiple times — leaving her with an inches-long gash above her right eye, prosecutors said.

The hoopster then allegedly “forcefully” squeezed Gondrezick’s neck with his hands, “causing her to experience difficulty breathing, redness and bruising to her neck, and substantial pain,” the complaint charges.

After being taken to NYU Langone Medical Center, doctors confirmed that Gondrezick — who previously played for the Indiana Fever and Chicago Sky — had suffered a fractured vertebra in her neck, the filing said.

Prosecutors with the Manhattan District Attorney’s Office had requested Porter’s bail be set at $100,000 during his arraignment, citing a history of alleged abuse against his girlfriend — including an incident when he rammed his car into hers.

Assistant District Attorney Mirah Curzer had also told the court that Porter, who lives in Houston, Texas, is known to have access to multiple firearms, and was arrested out of state in 2020 on gun charges, which were later dropped.

Judge Michael Ryan, however, instead set the NBA star’s bail at $75,000 and granted a full temporary restraining order against him.

Porter — who signed a $63.4 million contract with the Rockets in 2022 — was silent as he left the courthouse and ushered into a waiting car following his arraignment.

He is due back in court on Oct. 16.

His defence lawyer, Stephanie Kelemen of Quinn Emanuel Urquhart & Sullivan, LLP, didn’t return a request for comment.

Police sources have said the alleged assault on Gondrezick took place after the couple had gone out Sunday night and later returned to the hotel.

Gondrezick was asleep when her pro baller beau allegedly started beating her, the sources added.

“We are aware of the reports regarding Kevin Porter Jr.,” an NBA spokesperson told The Post in the wake of his arrest.

“The league office is in contact with the Houston Rockets and in the process of gathering more information.”

Meanwhile, Gondrezick’s sister reportedly took to her Instagram Stories to warn Porter to “count [his] days” after he was slapped with the charges, according to Clutch Points.

“@kevinporterjr if you think you gone touch my sister & not get touched,” Kalabrya Haskins wrote in a since-expired post. “Count ya f—ing days. Better hope and pray you’ll be able to ever walk again let alone dribble.

“You may have gotten away with this s–t in the past cause yo mama ain’t beat ya a–, but we spank lil punk a– painting nail sissy b—-es like you every day. Don’t show up to that crib. We gone do it to you. Lil b—h.”

Porter has a history of outbursts and was shipped from Cleveland to Houston in January 2021 after getting into a screaming match and tossing food when his locker was moved to a wall with younger players, The Athletic reported at the time.

He was also charged with improperly handling a firearm in a vehicle in Cleveland in November 2020 — though the case was dropped a month later.

In January 2022, he had to be separated from then-Houston assistant coach John Lucas during a halftime exchange that saw Porter lose his temper and throw an object, The Athletic reported.
