Conor McGregor hasn't fought in the UFC since 2016, but on Thursday he made his presence felt at media day for UFC 223 by crashing the event and reportedly getting into an altercation with some fighters on the card.

Here's video of McGregor attempting to throw a guard rail at one of the busses.  The video is from Felice Herrig's Instagram story and it contains some NSFW language.

This "invasion" of the Barclays Center comes a day after Dana White said he would strip Conor of his lightweight title after the Khabib Nurmagomedov and Max Holloway fight on Saturday night.

McGregor responded to what Dana said on Twitter and it's NSFW.
