DALLAS – UFC President Dana White isn’t sure what’s going to happen with Kevin Lee and his upcoming opponent, Michael Chiesa.

Still, he could manage a laugh following Friday’s wild “UFC Summer Kickoff” press conference, which previewed the organization’s upcoming schedule and top matchups.

The participants in one of those fights got an early start to the action. It took place on the press-conference dais at American Airlines Center in Dallas, where Chiesa (14-2 MMA, 7-2 UFC) charged after his opponent when Lee (15-2 MMA, 8-2 UFC) talked about his mom.

“He’s going to headline because of me,” said Lee, who meets Chiesa in UFC Fight Night 112’s main event on June 25. “After that, he’s going back to the prelims. I just hope he shows up, because I know his momma’s got tickets.”

Chiesa quickly became irate – “Don’t you ever talk about my (expletive) mom, or I’m going to smack the (expletive) out of you right now,” he warned – and ultimately charged after Lee, who seemed to land a clean punch during the melee (watch it above). While some type of punishment could be on the horizon, White did manage a laugh while discussing the heated scene.

“I heard that Chiesa said, ‘If that’s as hard as he hits, he’s in big trouble when we meet,'” White joked during a subsequent media scrum with reporters.

Here are Chiesa’s thoughts of the incident (via Twitter):

Still, during a media and fan event that had no shortage of heated moments, White said Lee and Chiesa went a bit far.

“The worst one was Lee hitting Chiesa,” White said. “That was a big one, when you actually land a solid punch.

” … I don’t know. I’ll go back and look at everything and talk to my team. We’ll figure it out.”

Chiesa, who’s No. 9 in the USA TODAY Sports/MMAjunkie MMA lightweight rankings, carries a three-fight winning streak into his bout with honorable mention Lee, who’s won four straight. Their UFC Fight Night 112 fight, which marks the first UFC-headlining opportunity for both fighters, airs on FS1 Chesapeake Arena in Oklahoma City, Okla.
