UFC star Conor McGregor caused a scene at Bellator 187 on Friday (Nov. 11) in Dublin, when he stormed the cage.

He attended the event in support of SBG Ireland teammate Charlie Ward, who defeated John Redmond on the Bellator prelims. Immediately after the win, McGregor leaped over the Bellator cage and tackled Ward in celebration. However, as referee Marc Goddard told McGregor to get out of the way, he lost it.

The referee turned around to evaluate Redmond, who was still down on the mat, but McGregor followed him across the cage and gave him a slight shove him in the back just as other officials intervened.

McGregor continued to advance toward him, pointing and yelling before eventually exiting.

Its unclear what exactly happened, but you can see it in the video above.
