Jon Jones and Daniel Cormier brawl at UFC 178 media day

Monday August 4th, 2014

Jon Jones and Daniel Cormier are scheduled to fight each other at UFC 178 in Las Vegas at the end of September. On Monday, they met at a press conference promoting the event and came to blows. 

It started when Jones rested his forehead against Cormier's. Cormier pushed Jones away and Jones lunged back at him and the pair tumbled off the small stage. A brief scrum followed before they were separated. 

Another video shows Jones landing a few big shots with his left while Cormier is on his back.

Afterwards, Cormier and Jones took their dispute to social media. 

Jones was originally scheduled to fight Alexander Gustaffson in a rematch of their UFC 165 Light Heavyweight championship match, but Gustaffson was forced to pull out with a knee injury. Cormier was announced as his replacement on July 23.
