On Monday night, Fox Sports 640 South Florida radio host Andy Slater took to his Twitter account to report that former friends Masvidal, 37, and Covington, 34, “got into a fight” outside local eatery Papi Steak, before police were called to the scene.

Soon afterward, Masvidal shared a video of himself on Twitter in a post, tagging Covington, who just over two weeks ago had defeated him in a UFC grudge match.

“Calling this the show-your-face challenge,” Masvidal said in the seconds-long clip, which can be viewed at the top of this article. “What’s up? I’m from Dade County. You talk that s***, you’ve got to back it up. That’s how my city rolls, man.”

In a further post shared on his Instagram Story, Masvidal also tagged Covington’s account as Kodak Black’s track “Super Gremlin” served as the soundtrack. A portion of the lyrics include: “Cause now it’s not safe for you / You switched like a p**** lil’ b****.”

Masvidal’s manager, Malki Kawa of First Round Management, chimed in on the situation, tweeting: “I’m hearing that a someone not from Miami who says he’s the king of it is missing a tooth. Can someone confirm this? I need the video asap.”

Covington has referred to himself as the “King of Miami” on Instagram. He has also taunted Masvidal in a series of posts after defeating him in the octagon.

TMZ shared video footage of the aftermath of the altercation, Covington appeared to be recounting the events of the night as he said: “He’s over here swinging, trying to come at me, and I ran out the back of the room.”

“How would he know I’m here?” Covington could be heard asking social media star Bob Menery, who responded: “I don’t know. You’re all over the internet.”

Newsweek has contacted representatives of Masvidal, Covington, the Miami Police Department and Papi Steak for comment.

Earlier in the night, Menery and YouTube stars the Nelk Boys posted video footage of Covington inside Papi Steak. In one clip shared by Menery, California native Covington was referred to as the “king” of Miami.

Reacting to the fallout from the incident, podcaster Menery tagged Masvidal in a Twitter post as he said he was “extremely disappointed” in the way that things had played out.

“Never had a problem with @GamebredFighter,” Menery wrote. “Extremely disappointed in the way he decided to handle his ongoing ‘beef’ that has already been decided in a regulated platform.”

The regulated platform in question was the octagon at Las Vegas’ T-Mobile Arena, where on March 5 Covington dominated Masvidal in an uneven fight that was the culmination of two former best friends becoming bitter foes.

“I was offbeat with the wrestling. I needed to wrestle harder,” Masvidal told Joe Rogan after the fight, per MMA Junkie. “My wrestling wasn’t there today. I was flat.”

Speaking in the octagon in the moments after he was named the victor, Covington spoke disparagingly of Masvidal as he took aim at Dustin Poirier.

“I just took care of Miami street trash. Now it’s time to take care of Louisiana swamp trash,” Covington said of his two former American Top Team teammates.

According to ESPN, Masvidal and Covington became close friends more than a decade ago as they bonded over training and their love of poker. The outlet reports that the fighters also once shared an apartment.

A host of incidents and a disagreement reportedly led to the pair’s falling out, with the pair publicly expressing their distaste for one another in recent years.
