The UFC Summer Kickoff press conference was certainly a wild one! Prior to the press conference starting, UFC light heavyweight champion Daniel Cormier and former UFC light heavyweight champion Jon Jones were engaged in a heated war of words backstage which saw the champ toss a water bottle at Jon Jones a-la Conor McGregor.

The second incident came during the press conference, and saw UFC lightweights Kevin Lee and Michael Chiesa both end up leaving the event after Chiesa stormed Lee for mentioning his mother. Lee quickly leapt into action and threw a punch at Chiesa before security guards broke the situation up and separated the two men.

Both matchups were announced today, with Cormier vs. Jones being announced for UFC 214 on July 29th, and Michael Chiesa vs. Kevin Lee being announced as the main event of UFC Fight Night: Oklahoma City.
