Knicks center Mitchell Robinson opened up about his mental health after he and Hawks guard Dyson Daniels were both ejected for fighting in Game 6 of their first-round playoff series Thursday night.

“Knew something was gone happen,” Robinson wrote in a Facebook post after the Knicks’ 140-89 series-clinching win — and the largest win in a playoff game in franchise history.

“My mental just not the same I’m just lost in the world at the moment.”

Robinson also reshared his pregame post that said, “Trying so hard to be calm.”

That comes as new video footage, appearing to be from a fan emerged on social media.

Taking to his Instagram Story, Robinson posted a video that showed a cartoon animal singing the message: “Hey, I gotta question cus I really need to know, do you ever get tired of being bitch ass n—a, .p—- ass n—a.”

Warning: Graphic Language

Things got chippy when OG Anunoby made a pair of free throws to extend the Knicks’ lead to 50 points with 4:39 remaining in the first half.

During the second attempt Robinson boxed out Daniels, who hit him with an elbow, before they came face-to-face and exchanged words.

They got tangled up and things escalated from there, with players and coaches from both teams holding the players back.

Atlanta center Onyeka Okongwu and the Knicks’ Jalen Brunson held Robinson back as the melee nearly spilled into the fans sitting courtside.

Hawks guard Nickeil Alexander-Walker and several coaches pulled Daniels away.

At one point, Knicks head coach Mike Brown ended up on the ground underneath the scuffle.

Robinson and Daniels both received technical fouls and were ejected.

The NBA hasn’t handed out any suspensions, as of Friday morning.

Robinson and Daniels’ beef had been building after they had a dust-up in Game 1 and Robinson got a technical, as noted by The Athletic’s Fred Katz.

The pair exchanged words throughout the series and things reached a tipping point Thursday night.

Meanwhile, on the court, it was a brutal beatdown by the KNicks.

Atlanta’s 83-36 deficit was the largest at halftime in NBA playoff history, according to ESPN.
