Conor McGregor slaps commissioner after confrontation with referee

Conor McGregor put on quite the show at Bellator 187 in Dublin.

UFC lightweight king Conor McGregor showed up to the 3Arena on Friday night to support his training partner Charlie Ward. Ward walked away with a first-round knockout win over Team Ryano's John Redmond, but the focus was all on McGregor after the fight. 'The Notorious' appeared cageside during the fight alongside Artem Lobov. While 'The Russian Hammer' remained typically reserved, McGregor was animated in shouting encouragement and instructions to Ward. Once the knockout blow landed, McGregor sped towards the fence, leapt into the cage and had a confrontation with referee Marc Goddard, the same official who warned him at UFC Gdansk. https://twitter.com/SportsJOEdotie/status/929066809315209227 McGregor eventually left the cage as the chaos simmered down, but immediately after leaving through the cage door, he went for a run around the cage and pumped up the crowd. He then climbed up another side of the cage and tried to embrace Ward. When a commissioner inside the cage tried to stop him from entering again, McGregor slapped him in the face. The commissioner then backed away as Ward charged towards the fence. McGregor helped him climb over and the two celebrated the win in front of the cheering crowd. https://www.instagram.com/p/BbU9TTUhuNO/ This is not a good look for McGregor.
