Jai Opetaia KO8 Huseyin Cinkara... One of the most avoided boxers in the sport, Australia's Jai Opetaia, defended his IBF cruiserweight title with a frightening eighth-round knockout of Germany's Huseyin Cinkara. The ending is a strong contender for knockout of the year, but it wasn't all sunshine for Opetaia. The 40 year-old Cinkara (23-1) was very lightly qualified for a world title shot and not expected to give Opetaia any problem, but Cinkara rocked Opetaia in the second round. There were also post-fight reports that Opetaia suffered a broken orbital and the knockout broke a bone in Cinkara's neck. The two men shook hands after the fight.
