Garbrandt stormed off from a television interview with him and Cruz on Wednesday, threatening to come to the room where Cruz was sitting. The exchange aired on The Fight Network in Canada.
When talk between the two turned to Garbrandt's girlfriend and Cruz commenting on her Instagram, it got heated.
"She shouldn't be hollering at me on social media," Cruz said. "Keep her to yourself. As far as I'm concerned, I did you and her a favor. She obviously wears the pants in the relationship or else she wouldn't be having to defend you."
Garbrandt then said he'd go to Cruz at that very moment.
"I'll come across there right now," Garbrandt said. "You're a room away."
Cruz egged him on, saying, "C'mon, turd. Let's go."
At that point, Garbrandt got up from his chair and asked manager Ali Abdel-Aziz to help him take off his microphone. Garbrandt left the room with UFC public-relations officials, apparently in search of Cruz. Cruz stayed on camera the whole time, saying he could hear Garbrandt throwing things outside.
"He has to do this, because this is what an alpha, a savage does," Cruz said mockingly.
