The Professional Fighters League event Friday apparently had an unsanctioned bout outside the cage.
Prominent MMA managers Abe Kawa and Ali Abdelaziz were involved in a "brief physical altercation where a battery was committed," the Las Vegas Metro Police Department told ESPN's Marc Raimondi.
Kawa, vice president of First Round Management, told Raimondi that Abdelaziz, the CEO of Dominance MMA, approached him in the crowd and slapped him on the right side of his face. The two were then quickly separated, according to Raimondi's sources.
Former UFC lightweight champion Anthony Pettis, who's represented by Kawa, said Abdelaziz slapped his manager "like a b----" and "was gone in 15 seconds."
On Saturday, Kawa expanded on his beef with Abdelaziz on Twitter:
The PFL said it intends to look into the incident.
"LVMPD officers were on scene and temporarily detained one of the subjects during the investigation," a police spokesperson said in a statement. "That subject was cooperative. He was issued a citation and released. No enforcement action was taken regarding the second subject, who was also cooperative. There were no significant injuries."
Abdelaziz's company boasts the likes of current UFC lightweight king Khabib Nurmagomedov, while Kawa's roster of fighters includes UFC light heavyweight champion Jon Jones.
