The UFC is “incredibly” disappointed with lightweight fighter Conor McGregor said Lawrence Epstein, COO of the sporting body. “We’ve come so far in legitimizing the sport and growing our business,” the exec told Cheddar in an in interview Friday. “[His behavior] is just not representative of who we are.” McGregor was arrested Thursday for an altercation in Brooklyn where he attacked a bus full of fellow UFC fighters, injuring two of them. “The first thing that’s got to happen is a criminal investigation,” Epstein said. Once that is over, the UFC will decide what to do internally and the option of kicking the fighter out of the UFC is not off the table, he said. McGregor is known for his flamboyant and provocative antics. For example, he swiped Floyd Mayweather Jr. with racist and demeaning slurs ahead of their highly anticipated UFC-boxing crossover match last year. The league, which celebrated its 25th anniversary Friday, hosts UFC 223 Saturday at the Barclays Center in Brooklyn. Since its inception, it’s [evolved](https://cheddar.com/videos/how-the-ufc-has-changed-over-its-25-year-history) from being a “very spectacle-oriented, niche, U.S.-centric sport to...a truly global brand,” said Epstein. He added that the body has worked very hard at making it a safe and regulated space with no tolerance for fighters like McGregor.
