WATCH: Conor McGregor causes chaos at Dublin MMA event after jumping into cage and sparking massive row with referee
Two-weight UFC world champion Conor McGregor has landed himself in further controversy by appearing to attack MMA referee Marc Goddard at a Dublin MMA event.
McGregor was at the Bellator 187 event at the 3Arena to watch his friend Charlie Ward take on John Redmond.
Ward had just knocked out Redmond in the final seconds of the first round when McGregor jumped into the cage to celebrate with his friend, in a clear breach of rules.
Goddard immediately ran to McGregor in an attempt to get him to leave the cage when the pair became involved in an altercation.
