In case you haven't heard the news or seen the videos, Conor McGregor crashed the UFC 223 media day and got into an altercation with some of the fighters while they were attempting to leave the Barclays Center.
McGregor and his entourage threw things at the busses and this video gives you a better view of something smashing the window of the bus.
(WARNING: Video NSFW due to explicit language)
We're not sure if Conor was the person that threw something at the window, but we do know one fighter was injured during the altercation.
McGregor, meanwhile, fled the scene with the people he invaded the arena with.
