Conor McGregor flipped off Dennis Siver before the first round of their “UFC Fight Night” match on Sunday night in Boston.
Referee Herb Dean brought the two together in the middle of the octagon and told them to shake hands just before the opening bell rang. McGregor reached out his hand to bump fists, but Siver snubbed him. McGregor responded by flipping off his opponent instead.
FOX Sports 1, which was airing the fight card, went dark to avoid the gesture making it out over the airwaves, but it was aired on international feeds.
