Media Day for UFC 223 took an unexpected and ugly turn, as a fighter bus was vandalized and several fighters assaulted. While backstage at the Barclays Center in Brooklyn, New York, UFC star Conor McGregor, his teammate Artem Lobov, and several of their crew stormed in and started throwing objects at the bus carrying several fighters that were set to compete on Saturday's card. Video courtesy of TMZ shows Conor McGregor picking up a dolly and throwing it at the bus, smashing the windows.

McGregor turns himself into Police

Hours after the incident, NBC New York and Newsday reported that McGregor was in custody after turning himself in.

A spokesperson commented that no charges were filed at that time. However, expect charges to be filed shortly. Two fighters, Michael Chiesa and Ray Borg, are off the card Saturday due to injuries suffered by the incident. Chiesa suffered facial cuts and was deemed medically unfit to compete Saturday.

Borg, was also transported to the hospital with injuries from shards of glass. Another fighter, Rose Namajunas, was shaken up after the incident but told the UFC she will continue to compete on Saturday's card. All of these fighters were currently participating in media day activities, as well as cutting weight ahead of their fights.

McGregor allegedly was able to get backstage after credentialed media, The Mac Life, let him and over 20 of his team through the back doors.

This was in retaliation to an event that took place earlier in the week, when McGregor's teammate, Lobov, was cornered and confronted by PPV headliner Khabib Nurmagomedov.

What's next for McGregor?

Dana White called Saturday's incident, 'most disgusting thing that has ever happened' in UFC history. Expect harsh ramifications coming down, with anything and everything on the table.

I don't expect just a fine to be delivered here, and wouldn't be shocked if the UFC releases McGregor from his contract.

Also, lawsuits should be coming from the company and its' fighters. Michael Chiesa and Ray Borg have had to pull out from their fights, which is monetary damages, to go along with assault. Disturbing the peace, vandalism will more than likely also be included when charges are pressed against McGregor. It's disturbing and continues the downward spiral McGregor has been on as of late. Just recently, he was allegedly involved in a bar fight in Ireland that included members of the Irish Mafia.
