He stood before a judge in jeans, saying nothing except "yes your honor".
McGregor, no stranger to WWE-type promotion skills, was fined in Nevada for throwing filled energy drink cans at 2016 opponent Nate Diaz at a news conference, and his sharp wit and crass talk helped make his novelty boxing loss to Floyd Mayweather Jr. past year the second-most lucrative combat sporting event of all time.
McGregor was released on a $50,000 bond and is expected back in court on June 14.
"Immediately, Lobov has been removed from this weekend's card and individuals involved in the incident are not welcome at tomorrow's ceremonial weigh-in or Saturday's event at Barclays Centre", the UFC said in the statement. McGregor tried to stick up for Lobov, a close friend, and apparently loaded a private jet with his best buds and flew to NY to rumble.

"We had a text session yesterday that was not very good", UFC president DAna White said during an appearance on ESPN's "Get Up!" on Friday. I don't think too serious. It was justified to him. Michael Chiesa, who was said to have suffered a cut face after police said a "hand truck" was thrown at a bus taking fighters away from the venue, tweeted to say the New York Athletic Commission had chose to pull him from his bout against Anthony Pettis. He was taken into custody in Brooklyn after turning himself in to the police.
McGregor and others were seen attacking the buses, that held other fighters, with objects such as dollies and guardrails.
White said during Wednesday's pre-fight press conference that "one of these guys will be the (lightweight) champion, period" in reference to Holloway and Nurmagomedov. White said credentialed journalists from McGregor's website, The Mac Life, let McGregor and a large entourage into Barclays Center.
"We were actually working on a new deal and a new plans for him. But when you bring in 20 hoodlums that flew in from Ireland to basically do this at our event, there's nothing like this that has ever happened".More news: Arvind Kejriwal supports TDP's demand on Andhra status
Lobov was yanked from the card and banned from the building.
Also charged with criminal mischief in the attack was Cian Cowley, who was alleged to have thrown a metal chair at one of the buses' windows. McGregor hasn't fought for UFC since November 2016 and was stripped this week of the 155-pound championship he had never defended. "You's'll strip me of nothing", he tweeted, invoking an expletive.
The New York Police Department had put out a warrant for McGregor's arrest.
