Opetaia was introduced as the Ring champion and Zuffa Boxing champion, with both titles highlighted throughout the official announcement. Mikaelian, meanwhile, was described only as a “two-time world champion,” with no mention of the WBC cruiserweight title he currently holds. “When I step into the ring on September 12 against Jai Opetaia in Las Vegas, I intend to defend my world championship,” Mikaelian said. “He’s proud to defend the Zuffa Boxing and Ring titles on the biggest stage.” About the AuthorPhil Jay is the Editor-in-Chief of World Boxing News (WBN), a BWAA-acknowledged boxing news website founded in 2010.
